1 Transmission Fluid Leaking problem

Failure Date: 04/15/2010

Transmission cooler line is leaking and needs to be replaced, when the weather turns cold the crimps fail and automatic trans fluid is lost causing the engine compartment to become a fire hazard when driving on the road. This is a very common problem due to the fact that the 4 other people I work with who have the same yr diesel truck or prior have had the exact same problem, not to mention countless other people online that I have talked to stating the same thing. Part number gm 20759971, gm 20759973, gm20759972. This is ridiculous that I as a consumer and everyone else have to pay for a defect that could possibly endanger my life or others in daily commuting. This is way to common to have us pay for the fact that they sent us out on the road with defective parts and are not willing to pay for there mistakes.

When the weather turns cold, the lines/crimps holding the rubber hose to the pipes fail and automatic transmission fluid is lost, sometimes in catastrophic manner, causing the vehicle to loose propulsion. Reports of failure are extremely common, and it is not unusual, that the lines may have been replaced 3 times within the 1st 50,000 miles. Gm has issued 'new, updated' parts, but they are no better than the original parts. The new part numbers are 20759971, 20759972, 20759973. While repair is covered on the 36k bumper to bumper warranty, there is no coverage on the 100k warranty. Gm should replace the lines free of charge for the 1st 100k miles with a hose that will not fail. Consumers can take the original gm line to a hydraulic shop, have the rubber portion of the lines replaced with standard hydraulic hose suitable for atf fluid and there are no further failures. If consumers can fix the lines, perhaps gm can find a solution.
