5 Transmission Fluid Leaking problem

Failure Date: 08/07/2012

I own a 2002 Chevrolet Trailblazer that has a defective transmission. The transmission has been completely replaced twice at approximately 24,000 miles and 45,000 miles. I learned recently on August 7, 2012, at just under 75,000 miles, that the transmission hoses were leaking fluid and that the transmission would need to be completely replaced again. I think general motors released a defective sports utility vehicle if the transmission needs to be replace approximately every 25,000 miles and these automobiles should be recalled as it could cause a safety hazard if the transmission stops working when someone is driving a Chevrolet Trailblazer.

7 Transmission Fluid Leaking problem

Failure Date: 11/21/2009

Transmission fluid began leaking from under my 2002 chevy Trailblazer in large quantities. I took it to a repair shop and was told that my transmission lines were rusted through, thus the reason for the leak. I was told that this is a problem with the Trailblazers and that it would be about $500 to replace the lines. The lines have been redesigned since 2002 and instead of only having to replace the two that are bad, all four will need to be replaced.
