My transmission cooler lines were leaking and I'm concerned about it due to the transmission fluid being a combustible material. If this material dripped onto a hot exhaust and ignited while parked in the "attached" garage of our home, it could pose a major safety hazard. . . Not to mention it could do to the neighbors home being relatively close. Thank you for your time.

Transmission lines that run from the transmission cooler next to the radiator continue to leak. The lines seem to leak more in colder climates. I am on my third set in 60 days. Transmission fluid was a flammable substance the last I knew.

Transmissions lines are continuing to leak. Have been to the dealer twice this year. Dealer has replaced cooler lines under warranty. Truck only has 32000 miles on it. Dealer needs to come up with a permanent fix, or it is going to cost the consumer a lot of money to keep having the transmission lines replaced.
