Lake Forest, Illinois, May 8, 2003 - Tenneco Automotive (NYSE: TEN) announced
today that Neal Yanos has been promoted to senior vice president and general

effective immediately.

Since December 2000, Mr. Yanos has been responsible for the company's North
American original equipment ride control business unit, which serves major light

improved its position in the heavy duty and specialty markets during the past
two years.

"Neal Yanos has done an outstanding job in turning around our North American
original equipment ride control business and I am looking forward to his
disciplined leadership in meeting the many challenges of the North American
aftermarket," said Mark P. Frissora, chairman and CEO, Tenneco Automotive. "We
intend to capitalize



                                     -More-


on engineering and manufacturing synergies between the OE and aftermarket
businesses and continue to leverage our technology advances between the two
groups."

"Bringing these two business units under one general manager will help bring a
more integrated approach to solutions for our ride control customers while at
the same time, strengthening our strategies for growth in the exhaust
aftermarket through a more product-focused structure," said Frissora.

Mr. Yanos joined Tenneco Automotive in 1988 and has held a broad range of
management assignments supporting both the Aftermarket and OE businesses,
including product engineering, manufacturing, marketing, strategic planning and
finance. Prior to being named vice president of the company's North American
original equipment ride control business unit in late 2000, Yanos was director
of the North American original equipment General Motors and VW business.

Mr. Yanos holds a bachelor's degree in engineering from Purdue University and a
master's degree in business from the University of Toledo.

Neal Yanos is on the company's senior management team and will continue to
report to Chairman and CEO Mark Frissora. He will remain located at the
company's North America original equipment headquarters in Monroe, Michigan.
