     o    Full year net income before accounting change down 12 percent --
          adjusted full year net income up 184 percent

Lake Forest, Illinois, January 27, 2004 -- Tenneco Automotive (NYSE: TEN)
announced today that the company reported a fourth quarter net loss of $2
million, or 4-cents per diluted share, compared with fourth quarter 2002 net
income of $9 million, or 21-cents per diluted share. The company reported full
year 2003 net income of $27 million, or 65-cents per diluted share, compared
with net income before an accounting change in 2002 of $31 million, or 74-cents
per diluted share.

"When you consider our quarter-over-quarter results on an operational basis,
excluding certain items, our strong cash and earnings performance in the quarter
helped us deliver our best operational year since becoming a stand-alone
company," said Mark P. Frissora, chairman and CEO, Tenneco Automotive.

Adjusted for the items described below, fourth quarter 2003 net income was $2
million, or 6-cents per diluted share, versus a loss of $7 million, or 17-cents
per diluted share, in the fourth quarter of 2002. Adjusted for the items
described below, full year 2003 net income was $23 million, or 55-cents per
diluted share, a 162 percent increase in earnings per share compared with 2002
adjusted net income of $8 million, or 21-cents per diluted share. See the tables
that reconcile GAAP results to non-GAAP results, which are in attachment 2 to
the press release.

ADJUSTMENTS TO REPORTED FOURTH QUARTER 2003 RESULTS ARE:

     o    expenses of $9 million pre-tax, $6 million after-tax, or 13-cents per
          share, associated with refinancing of the company's senior debt;

     o    restructuring expenses of $1 million pre-tax, $1 million after-tax, or
          2-cents per share;

     o    a benefit of $3 million, or 5-cents per share, related to a foreign
          tax adjustment.

ADJUSTMENTS TO REPORTED FOURTH QUARTER 2002 RESULTS ARE:

     o    net benefits of $16 million after-tax, or 38-cents per share, for
          adjustments to restructuring costs and taxes.

ADJUSTMENTS TO REPORTED FULL YEAR 2003 RESULTS ARE:

     o    restructuring and related expenses of $8 million pre-tax, $5 million
          after-tax, or 13-cents per share;

     o    a benefit of $17 million, or 41-cents per share, related to several
          tax adjustments.


                                       1


ADJUSTMENTS TO REPORTED FULL YEAR 2002 RESULTS ARE:

     o    a net benefit of $23 million after-tax, or 53-cents per share, due to
          restructuring and related activities; costs associated with the
          amendment of the senior debt agreement; a gain on the sale of a
          facility; and a benefit related to several tax adjustments.

"We improved in every region and I am especially pleased with the turnaround in
our European original equipment operations," said Frissora. "Europe also took
the lead in winning significant new ride and emissions control business. We were
awarded more than $900 million in new business in 2003 for OE platforms expected
to begin production in 2004 through 2007. We are also encouraged by some
strengthening in the North America aftermarket where revenue grew
quarter-over-quarter for the first time since the second quarter of 2002."

FOURTH QUARTER PERFORMANCE

The company's fourth quarter 2003 results benefited from higher volumes,
improved manufacturing efficiencies and favorable currency exchange rates.
However, results were negatively impacted by $4 million in higher interest
expense on the company's debt refinancing.

Fourth quarter revenue was $933 million, compared with $846 million in fourth
quarter 2002, a 10 percent increase. Adjusted for $86 million in favorable
currency, revenue was slightly up quarter-over-quarter.

The company's reported EBIT (earnings before interest, taxes, and minority
interest) increased 27 percent to $40 million in the fourth quarter, compared
with $31 million in fourth quarter 2002. Adjusted for certain items described
above (see attachment 2), EBIT was $41 million, a 51 percent increase compared
with fourth quarter 2002 adjusted EBIT of $27 million. The company generated $76
million in cash flow before financing activities during the quarter, largely
driven by $68 million in cash from working capital improvements.

Reported EBIT before depreciation and amortization expense (EBITDA) was $83
million for the quarter, an 18 percent increase compared with $71 million in
fourth quarter 2002. Adjusted for certain items described above (see attachment
2), fourth quarter EBITDA was $84 million, a 28 percent increase versus adjusted
fourth quarter 2002 EBITDA of $67 million.

The Company decreased its SGA&E (selling, general, administrative and
engineering) expense to 11.3 percent of sales in the quarter compared with 11.6
percent in fourth quarter 2002. The higher margin aftermarket continues to
represent a smaller percentage of revenues and gross margin. Gross margin was
20.2 percent in the quarter, compared with 20.0 percent reported in fourth
quarter 2002. Without the benefits of an income adjustment related to
restructuring costs, fourth quarter 2002 gross margin would have been 19.7
percent.

The company operated well within the requirements of its bank debt covenants in
the quarter. At December 31, the leverage ratio was 4.17, below the maximum
limit of 5.00;


                                       2



the fixed charge coverage ratio was 1.87, exceeding the minimum required ratio
of 1.00; and the interest coverage ratio was 3.04, exceeding the minimum
required ratio of 1.95.


FULL YEAR PERFORMANCE

The company reported 2003 revenue of $3.8 billion, a 9 percent increase over
2002. Adjusted for the impact of favorable currency, revenue increased 1
percent.

Full year reported EBIT was $176 million, a 4 percent increase compared with
2002 EBIT of $169 million. Adjusted for certain items, 2003 EBIT was $184
million, compared with adjusted 2002 EBIT of $162 million. For the full year,
Tenneco Automotive reported net cash before financing activities of $154
million, up 90 percent from a year ago. The company strengthened its financial
position in 2003, ending the year with cash balances of $145 million and total
debt at $1.430 billion, or debt net of cash balances of $1.285 billion, the
lowest level since becoming a stand-alone company.

Tenneco Automotive reported EBITDA for the full year of $339 million, an
increase from $313 million reported in 2002. EBITDA was $347 million adjusted
for certain items described above (see attachment 2), compared with 2002
adjusted EBITDA of $306 million.

The company reported SGA&E for the year of 11.4 percent of sales, meeting its
2003 goal of maintaining SGA&E expense at less than 12 percent of sales. Gross
margin for 2003 was 20.5 percent versus 20.9 percent in 2002. The decline was
driven by a lower percentage of sales generated by the higher margin aftermarket
business. The company also achieved its Project Genesis restructuring goals for
the year, generating $29 million in savings. Manufacturing improvements driven
by the company's Six Sigma initiative generated an additional $27 million in
savings in 2003.

FOURTH QUARTER - NORTH AMERICA

     o    North American original equipment revenue was $347 million for the
          quarter versus $338 million in fourth quarter 2002. Excluding the
          impact of lower pass-through catalytic converter sales, revenue was
          $270 million, up 2 percent versus a market decline of almost one
          percent. Higher ride control volumes drove the increase.

     o    North American aftermarket revenue was $99 million, up 12 percent
          versus fourth quarter 2002 revenue of $88 million. The increase was
          driven by an 11 percent increase in ride control sales and a 14
          percent increase in emissions control sales.

     o    Reported EBIT for North American operations was $22 million compared
          with $21 million reported in the fourth quarter of 2002. Adjusted for
          $1 million in restructuring related expenses, EBIT in fourth quarter
          2003 was $23 million, versus EBIT of $21 million in the same period
          one year ago. The EBIT improvement was driven by higher volumes,
          improved manufacturing efficiency and cost control measures.




                                       3



FOURTH QUARTER - EUROPE

     o    European original equipment revenue increased to $290 million from
          $253 million in fourth quarter 2002. Before the impact of favorable
          currency and pass-through catalytic converter sales, revenue was $193
          million, down less than one percent and even with the market decline.
          A 33 percent increase in OE ride control volumes offset a 12 percent
          decline in emissions control volumes, adjusted for currency and
          pass-through sales.

     o    European aftermarket revenue was $76 million compared with $70 million
          in fourth quarter 2002. Excluding the impact of favorable currency,
          revenue was $62 million. The revenue decline was the result of
          continued market softness in both ride and emissions control.

     o    Reported European EBIT was $7 million compared with reported fourth
          quarter 2002 EBIT of $3 million, or zero adjusted for a net benefit of
          $3 million for a favorable adjustment in the estimate to complete
          Project Genesis restructuring, net of restructuring related expenses.
          Favorable currency, higher OE ride control volumes, improved
          manufacturing efficiencies and tight cost controls drove the EBIT
          improvement.

FOURTH QUARTER - REST OF WORLD

     o    The company's Australian operations increased revenue to $45 million
          from $33 million in the fourth quarter 2002. Revenue increased
          2 percent to $34 million, excluding the impact of favorable currency.
          The revenue gain was driven by higher OE volumes.

     o    Revenue from Asian operations increased to $43 million from $39
          million in fourth quarter 2002, primarily driven by growing OE
          revenues in China.

     o    The company reported revenue from South American operations of $33
          million, a 33 percent increase over fourth quarter 2002 revenue of $25
          million. Revenue was impacted by $5 million in favorable currency and
          higher OE volumes, primarily in Brazil.

     o    Reported combined EBIT for Asia, South America and Australia was $11
          million in the fourth quarter versus $7 million in the fourth quarter
          of 2002. The improvement in reported EBIT was due to manufacturing
          efficiencies, increased volumes and favorable currency exchange rates.
          Fourth quarter 2002 results include a net benefit of $1 million for an
          adjustment in the estimate to complete Project Genesis.

2004 OUTLOOK

In 2004, the company will maintain its emphasis on aggressive cost management,
top-line growth and cash generation to further reduce its debt. The company's
long-term goals include reducing SGA&E expense to 10 percent of sales; improving
gross margin to 22 percent of sales; and generating at least $100 million in new
business annually. For 2004, the company also anticipates generating an
additional $30 million in cash from working capital improvements.

"Our strategy is to capitalize on growth opportunities with advanced
technologies and in new markets, such as China and Eastern Europe, while
continuing our intense focus on cost management and manufacturing improvement
initiatives," said Frissora. "In the aftermarket, we expect to grow with new
products and in categories beyond our


                                       4



traditional product lines, while continuing to size our European aftermarket
business to the market."

The company anticipates that its original equipment book of business in 2004 and
2005 will be about $75 million and $315 million higher, respectively, than the
2003 book of business. Before pass-through catalytic converter sales, the book
of business is expected to be about $45 million and $270 million higher than
2003 in 2004 and 2005, respectively. These revenue estimates are based on
original equipment manufacturers' programs that have been formally awarded to
the company as well as programs where the company is highly confident that it
will be awarded business based on informal customer indications, Tenneco
Automotive's status as a supplier on the existing program, and the relationship
with the customer.

Automotive's fourth quarter and full year 2003 results.

pricing for the applicable program over its life, and is subject to increases or
decreases due to changes in customer requirements, customer and consumer
preferences, and the number of vehicles actually produced by customers; (v) the
cyclical nature of the global vehicular industry, including the performance of

including longer product lives of automobile parts and the cyclicality of
automotive production and sales of automobiles which include the company's
products, and the potential negative impact on the company's revenues and
margins from such products; (vi) the cost and outcome of existing and any future
legal proceedings, and compliance with changes in regulations, including
environmental regulations; (vii) workforce factors such as strikes or labor
interruptions; (viii) material substitutions and increases in the costs of raw
materials; (ix) the company's continued success in cost reduction and cash
management programs and its ability to execute restructuring and other cost

policies; (xiii) acts of war, riots or terrorism, including, but not limited to
the events taking place in the Middle East, the current military action in Iraq
and the continuing war on terrorism, as well as actions taken or to be taken by
the United States or other governments as a result of further acts or threats of
terrorism, and the impact of these acts on economic, financial and social
conditions in the countries where we operate and (xiv) the timing and occurrence
(or non-occurrence) of transactions and events which may be subject to
circumstances beyond the control of the company and its subsidiaries. The
company undertakes no obligation to update any forward-looking statement to

(1) Generally Accepted Accounting Principles

(2) EBITDA represents income before cumulative effect of change in accounting
principle, interest expense, income taxes, minority interest and depreciation
and amortization. EBITDA is not a calculation based upon generally accepted
accounting principles. The amounts included in the EBITDA calculation, however,
are derived from amounts included in the historical statements of income data.
In addition, EBITDA should not be considered as an alternative to net income or
operating income as an indicator of the company's operating performance, or as
an alternative to operating cash flows as a measure of liquidity. Tenneco
Automotive has presented EBITDA because it regularly reviews EBITDA as a measure
of the company's ability to incur and service debt. In addition, Tenneco
Automotive believes its debt holders utilize and analyze our EBITDA for similar
purposes. Tenneco Automotive also believes EBITDA assists investors in comparing
a company's performance on a consistent basis without regard to depreciation and
amortization, which can vary significantly depending upon many factors. However,
the EBITDA measure presented may not always be comparable to similarly titled
measures reported by other companies due to differences in the components of the
calculation.

(1) Generally Accepted Accounting Principles

(2) Tenneco Automotive presents the above reconciliation of GAAP to non-GAAP
earnings measures in order to reflect the results for the fourth quarters of
2003 and 2002 in a manner that allows a better understanding of the results of
operational activities separate from the financial impact of decisions made for
the long-term benefit of the company. Adjustments similar to the ones reflected
above have been recorded in earlier periods, and similar types of adjustments
can reasonably be expected to be recorded in future periods. Using only the
non-GAAP earnings measures to analyze earnings would have material limitations
because its calculation is based on the subjective determinations of management
regarding the nature and classification of events and circumstances that
investors may find material. Management compensates for these limitations by
utilizing both GAAP and non-GAAP earnings measures reflected above to understand
and analyze the results of the business. The company believes investors find the
non-GAAP information helpful in understanding the ongoing performance of
operations separate from items that may have a disproportionate positive or
negative impact on the company's financial results in any particular period.

(3) See Reconciliation of GAAP Net Income to EBITDA on previous page. EBITDA
represents income before cumulative effect of change in accounting principle,
interest expense, income taxes, minority interest and depreciation and
amortization. EBITDA is not a calculation based upon generally accepted
accounting principles. The amounts included in the EBITDA calculation, however,
are derived from amounts included in the historical statements of income data.
In addition, EBITDA should not be considered as an alternative to net income or
operating income as an indicator of the company's operating performance, or as
an alternative to operating cash flows as a measure of liquidity. Tenneco
Automotive has presented EBITDA because it regularly reviews EBITDA as a measure

the EBITDA measure presented may not always be comparable to similarly titled

calculation.

(1) Generally Accepted Accounting Principles

(2) EBITDA represents income before cumulative effect of change in accounting
principle, interest expense, income taxes, minority interest and depreciation
and amortization. EBITDA is not a calculation based upon generally accepted
accounting principles. The amounts included in the EBITDA calculation, however,
are derived from amounts included in the historical statements of income data.
In addition, EBITDA should not be considered as an alternative to net income or
operating income as an indicator of the company's operating performance, or as
an alternative to operating cash flows as a measure of liquidity. Tenneco
Automotive has presented EBITDA because it regularly reviews EBITDA as a measure
of the company's ability to incur and service debt. In addition, Tenneco
Automotive believes its debt holders utilize and analyze our EBITDA for similar
purposes. Tenneco Automotive also believes EBITDA assists investors in comparing
a company's performance on a consistent basis without regard to depreciation and
amortization, which can vary significantly depending upon many factors. However,
the EBITDA measure presented may not always be comparable to similarly titled
measures reported by other companies due to differences in the components of the
calculation.

(1) Generally Accepted Accounting Principles

(2) Tenneco Automotive presents the above reconciliation of GAAP to non-GAAP
earnings measures in order to reflect the results for the years of 2003 and 2002
in a manner that allows a better understanding of the results of operational
activities separate from the financial impact of decisions made for the
long-term benefit of the company. Adjustments similar to the ones reflected
above have been recorded in earlier periods, and similar types of adjustments
can reasonably be expected to be recorded in future periods. Using only the
non-GAAP earnings measures to analyze earnings would have material limitations
because its calculation is based on the subjective determinations of management
regarding the nature and classification of events and circumstances that
investors may find material. Management compensates for these limitations by
utilizing both GAAP and non-GAAP earnings measures reflected above to understand
and analyze the results of the business. The company believes investors find the
non-GAAP information helpful in understanding the ongoing performance of
operations separate from items that may have a disproportionate positive or
negative impact on the company's financial results in any particular period.

(3) See Reconciliation of GAAP Net Income to EBITDA on previous page. EBITDA
represents income before cumulative effect of change in accounting principle,
interest expense, income taxes, minority interest and depreciation and
amortization. EBITDA is not a calculation based upon generally accepted
accounting principles. The amounts included in the EBITDA calculation, however,
are derived from amounts included in the historical statements of income data.
In addition, EBITDA should not be considered as an alternative to net income or
operating income as an indicator of the company's operating performance, or as
an alternative to operating cash flows as a measure of liquidity. Tenneco
Automotive has presented EBITDA because it regularly reviews EBITDA as a measure

amortization, which can vary significantly depending upon many factors. However,
the EBITDA measure presented may not always be comparable to similarly titled
measures reported by other companies due to differences in the components of the
calculation.

Tenneco Automotive presents the above reconciliation of revenues in order to
reflect the trend in the company's sales, in various product lines and
geographical regions, separately from the effects of doing business in
currencies other than the U.S. dollar. Additionally, pass-through catalytic
converter sales include precious metals pricing, which may be volatile. While
Tenneco Automotive's original equipment customers assume the risk of this
volatility, it impacts reported revenue. Excluding pass-through catalytic
converter sales removes this impact. Tenneco Automotive uses this information to
analyze the trend in revenues before these factors. Tenneco Automotive believes
investors find this information useful in understanding period to period
comparisons in the company's revenues

Tenneco Automotive presents the above reconciliation of revenues in order to
reflect the trend in the company's sales, in various product lines and
geographical regions, separately from the effects of doing business in
currencies other than the U.S. dollar. Additionally, pass-through catalytic
converter sales include precious metals pricing, which may be volatile. While
Tenneco Automotive's original equipment customers assume the risk of this
volatility, it impacts reported revenue. Excluding pass-through catalytic
converter sales removes this impact. Tenneco Automotive uses this information to
analyze the trend in revenues before these factors. Tenneco Automotive believes
investors find this information useful in understanding period to period
comparisons in the company's revenues
