                   TENNECO AUTOMOTIVE REPORTS IMPROVED RESULTS

     -    Company reports EPS of 2-cents per share, reversing prior year net
          loss
     -    EBIT improves 15 percent to $31 million
     -    EBITDA improves 14 percent to $70 million
     -    Revenues increase 14 percent as favorable platform mix helps original
          equipment sales outpace market
     -    Restructuring program realizes $6 million in savings


Lake Forest, Illinois, April 22, 2003 - Tenneco Automotive (NYSE: TEN) announced
today that the company reported net income of $1 million, or 2-cents per share,
in the first quarter of 2003, versus a net loss of $2 million, or 5-cents per
share before the cumulative effect of a change in accounting principle, for the
first quarter of 2002. First Call's analyst consensus estimate for the quarter
was a loss of 4-cents per share. EBIT (income before interest, taxes and
minority interest) improved to $31 million in the quarter, a 15 percent increase
over $27 million the previous year. EBITDA was $70 million for the quarter, a 14
percent improvement over first quarter 2002 EBITDA of $61 million.

The first quarter 2003 results include pre-tax restructuring and restructuring
related costs of $5 million, or 7-cents per share, and a tax benefit from
resolution of outstanding tax issues of $3 million, or 8-cents per share. The
first quarter 2002 results include a pre-tax non-accruable restructuring expense
of $1 million, or one cent per share; pre-tax charges associated with the
company's amendment of its senior debt agreements of $2 million, or 3-cents per
share; and income from a tax benefit of $4 million, or 10-cents per share. (See
the table entitled, "Reconciliation of GAAP Results to non-GAAP Results"
attached to this press release for more information about these adjustments and
other non-GAAP results in this press release.)

                                                                               1


The company reported revenue of $921 million for the quarter, up 14 percent
versus $809 million in the first quarter of 2002. Favorable currency exchange
rates benefited revenue by $54 million in the quarter. Excluding the impact of
currency, revenue was up 7 percent.

"We are pleased with our results, especially given industry and economic
uncertainties at the beginning of the year. We benefited this quarter from our
strong position on top-selling vehicle platforms as North American OE production
volumes remained strong. We also continue to see steady improvement in our
European original equipment exhaust business where revenues are up
year-over-year, and gross margins improved over last quarter and are now even
with first quarter 2002," said Mark P. Frissora, chairman and CEO, Tenneco
Automotive. "We still face challenges in the global aftermarket and are
aggressively taking costs out of the businesses, including flexing our
operations, while continuing to invest strategically in promoting our products
and premium brands."

The company generated $10 million in positive cash flow before financing
activities during the quarter compared with $14 million in the first quarter of
2002. The company used more cash in the quarter, compared with first quarter
2002, primarily to prepare for platform launches and for seasonal inventory
builds. More aggressive receivables and payables management steps were taken in
the quarter to offset this heavier cash use and to help preserve liquidity given
the uncertainties in the market for the second quarter of 2003. Total bank and
bond debt was $1.443 billion at quarter-end compared with $1.445 billion at the
end of 2002.

Tenneco Automotive again significantly outperformed the requirements of its bank
debt covenants. At March 31, the leverage ratio was 4.35, below the maximum
limit of 5.75; the fixed charge coverage ratio was 1.31, exceeding the minimum
required ratio of 0.80; and the interest coverage ratio was 2.31, exceeding the
minimum required ratio of 1.65.

The company continues to improve its operational efficiency and realized $6
million in savings during the quarter from implementation of its Project Genesis
restructuring program and $6 million in savings from Six Sigma initiatives. The
company's SGA&E (selling, general and administrative expense plus engineering,
research and development expense) as a percent of sales was 11.6 percent, within
management's goal for the year of maintaining this ratio at less than 12
percent.

"We made progress this quarter as our original equipment businesses fueled
top-line growth and we continued to successfully execute our restructuring and
cost-cutting initiatives. We were especially encouraged that our North American
aftermarket business equaled last year's profitability on softer sales," said
Frissora. "Going forward, we're cautiously optimistic about OE revenue growth
given our platform mix and we're launching new products and marketing programs
to help counter industry conditions in the aftermarket. We also remain intensely
focused on generating cash and see solid opportunities to reduce inventories and
improve our working capital performance."

NORTH AMERICA

- -        Strong OE production and the company's presence on high volume OE
         vehicle models drove North American original equipment revenue to $373
         million in the quarter, a 9 percent increase over first quarter 2002
         revenue of $341 million. Excluding catalytic converter pass-through
         sales, revenue increased 12 percent.

- -        Original equipment revenue included a 7 percent increase in heavy-duty
         revenues versus last year.

- -        North American aftermarket revenue was $108 million versus $126 million
         one year ago. Sales were negatively impacted by lower consumer
         confidence and the continued universal decline in the exhaust market.
         Despite the decrease in aftermarket revenue, EBIT for that business was
         flat on a year-over-year comparison.

- -        EBIT for North American operations was $28 million compared with $19
         million in the first quarter of 2002. The 46 percent EBIT improvement
         was primarily driven by OE volumes, improved operating efficiency and
         continued tight cost controls. EBITDA was $50 million versus $40
         million in first quarter 2002.

- -        First quarter 2003 EBIT results include $3 million in restructuring and
         restructuring related costs. First quarter 2002 EBIT results include $1
         million in restructuring related costs and $1 million in charges
         associated with the company's amendment of its senior debt agreements.

EUROPE

- -        European original equipment revenue increased 30 percent to $269
         million from $207 million in the first quarter of 2002. Excluding
         catalytic converter pass-through sales and the impact of favorable
         currency exchange rates, revenue would have increased 5 percent.

- -        The company's European aftermarket revenue increased to $76 million,
         versus $65 million one year ago. Excluding the impact of currency,
         revenue would have decreased 4 percent.

- -        European EBIT was a loss of $1 million, compared with positive EBIT of
         $5 million in the first quarter of 2002. EBIT was impacted by a $4
         million increase in depreciation and higher aftermarket promotional
         costs. EBITDA was $13 million compared with $15 million in first
         quarter 2002.

- -        First quarter 2003 EBIT results include $2 million in restructuring and
         restructuring related costs. First quarter 2002 EBIT results include $1
         million in charges associated with the company's amendment of its
         senior debt agreements and no restructuring costs.

REST OF WORLD

- -        The company's Asian operations reported revenue of $36 million, versus
         $18 million one year ago. Revenue growth was primarily driven by strong
         China OE volumes and higher pass-through sales.


                                                                               3



- -        In South America, the company reported revenue of $26 million, flat
         compared with the previous year. Unfavorable currency exchange rates
         negatively impacted revenue by $7 million, which was offset by stronger
         OE and aftermarket volumes.

- -        The company's Australian operations reported revenue of $33 million for
         the quarter, a 27 percent increase over first quarter 2002 revenue of
         $26 million. A favorable currency exchange rate impacted revenue by $4
         million. Strong OE production offset softer sales in both the ride
         control and exhaust segments of the aftermarket.

- -        Combined EBIT for Asia, South America and Australia was $4 million,
         versus $3 million in the first quarter of 2002. Higher OE volumes in
         all the regions were primarily responsible for the increase. Combined
         EBITDA for rest of world was $7 million compared with $6 million in
         first quarter 2002.

quarter 2003 results.

(a) Generally Accepted Accounting Principles

(b) Tenneco Automotive presents the above reconciliation of GAAP to non-GAAP
    results in order to reflect the results for the first 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.
    However, the management of Tenneco Automotive uses both the GAAP and
    non-GAAP measures reflected above to understand and analyze the results of
    its business, and believes investors find this information helpful in
    understanding the ongoing performance of operations separate from items that
    may have a disproportional positive or negative impact on the company's
    financial results in any particular period.

(c)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.


                                                                   ATTACHMENT 2

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.
