Exhibit No. 99.1

TENNECO AUTOMOTIVE PRICES $500,000,000 OF SENIOR SUBORDINATED NOTES


LAKE FOREST, ILLINOIS, NOVEMBER 9, 2004 - Tenneco Automotive (NYSE:TEN)
announced today that it has priced a private placement offering of $500,000,000
of 8-5/8 percent senior subordinated notes due November 15, 2014. The net
proceeds of this transaction, expected to be about $487 million, together with
cash on hand, will be used to redeem $500,000,000 aggregate principle amount of
its outstanding 11-5/8 percent senior subordinated notes due in 2009.

These transactions are expected to reduce the company's annual interest expense
by approximately $15 million annually, or 20-cents per diluted share.

The company expects to record non-recurring pre-tax charges related to the
redemption premium and fees and the write-off of deferred debt issuance costs of
approximately $29 million and $9 million, respectively, in the period in which
the redemption is completed.

The new notes will be senior subordinated obligations of Tenneco Automotive and
will mature on November 15, 2014 with interest payable semi-annually, beginning
on May 15, 2005. The notes will be guaranteed by each of Tenneco Automotive's
material domestic wholly-owned subsidiaries.

The closing of the offering is conditioned on consent of the company's senior
bank lenders to permit the transactions on the terms proposed and other
customary conditions. Although there can be no assurance, the company currently
expects to complete the offering in mid-November and the redemption by
mid-December.
