2003 GMC Envoy XL transmission problems

Filed Nov 26, 2013 · Electrical, Transmission · MI

This is the second occurrence of an issue with the vehicles manual switch for 2hi,awd,4hi,4low. The dealer I bought the used vehicle from fixed the issue right after purchase and I'm having another problem with the switch. I try to select anything besides 2hi and the selector will just continue to blink on the selection without any action. Sometimes the service 4wd will illuminate on the dash. This seems like a frequent occurrence/complaint of other envoy owners online.

One of the oil cooler line on my 2003 gmc envoy is cracked and leaking transmission fluid on the cataylic converter. This is a serious fire hazard due to the extremely high temperature of the converter during normal operations.

I have an 03 envoy slt. The fan clutch just went out 3 days ago. I had heard the ticking sound before, but never the loud airplane sound until it finally broke completely. The dealer wants $720. After calling gm customer service (manny at 1866-952-4368, ext. 3-2786), he said because I have 119,000 miles on my car, there is not much they can do. I looked into this problem online and found this is a common problem. When I explained this to gm, he still doesn't know a lot about the issue.

Transmission line mounted too close to catalytic converter resulting in rubbing action that resulted in a hole in the transmission line spraying fluid on hot exhaust parts. Had to pay to have hose replaced. Don't know if the eventual failure of the transmission at 73k miles was related, but had to pay $2700 to get a new one installed.
