Hi, My 2003 Envoy jumps constantly from 4th to 5th(overdrive) at speeds mostly between 63-68 MPH (which is how fast I used to drive). My research points to the Transmission Control Module but it's confusing whether or not that unit has to be replaced completely or can be "re-programmed". Other articles point to a servo or even a loose electrical wire. I also notice a manual overdrive shift kit is available for purchase from the dealer and I'll resort to that if I have to. Hopefully I could install that myself. Aamco wants me to bring it in for their free diagnostic but I haven't had good luck with them as usually they take an R&R approach until it's finally fixed. Any suggestions would be appreciated. Thank you very much. -Doug |

| I have been having a problem for about 4 months now, where you put the key in turn it, everything comes on except it won't start, starter not clicking or anything.So they said get a new battery which we did and the problem continue. And then when it did start it would idle real rough and the check engine light would come sometimes, but if you turned it off and back on, if it start it would usually run fine and the check engine light would go out. Took to the dealership again and they said there was carbon build up and it just needed some maintenance, so paid for that like $300. 2 days later it would start again. When it doesn't start the the security light does NOT blink or come one and you cant even take it out of park. So the same problems are there still. Took it in again they said it needed a new throttle body??? I said are you kidding me, keep looking. So they replaced the PCM because there was a TSB on it. The whole time we have had a case file with GM headquarters because the local dealership is horrible. Saturday it started doing it really bad, you could usually get it to start in about 10minutes or so, but now it goes hours. So I called the dealership for them to get a tow truck and come pick it up and they said sure, I stated I wanted a courtesy vehicle and they said enterprise is closed, I said 13 miles away there is one open and they continued to say no. So called GM headquarters and they spoke with the dealership, still nothing. So I paid an online service to look up the owners name, address and telephone number and called him(he owns something like 8 new dealerships in the Charleston area) he seemed he was going to be helpful and stated he could not get me a loaner car till Monday. So my wife got the car started and took it in on Monday, they started accusing her of lieing and all this other stuff and would not give her a loaner car(we have 55k miles on our car warranty only ran out at like 45k when we started having this issue) because we are outside of warranty and they want to keep the vehicle for a week or 2 because they don't know what is wrong. So we called GM headquarters again, and they said the best thing to do now is for us to contact a lawyer. Anybody who has had experiences filling a claim against GM, I would really appreciate some information. | |

I have a 2006 envoy and 2 weeks ago it stalled at a light and now it stalls occasionally on the hoghway and will not start at times like it has a dead battery yet all the lights will come on. My friend ran a diagnostics check and found no fault codes and I know I am gonna get killed in this car. i am in no position to go to the dealer and they also find nothing and then charge me to replace an ignition , computer, or several other things. At this point all I have is a case at GM and I am extremely worried. Anyone else having this issue or problem? Rich L.

Replying to: jillianne (Apr 11, 2008 5:43 am)  I am having the same problems you were having, can you tell me the dealership name and number you took your car to. I have an appointment Monday and would like to have all my ducks in a row. I find it odd and I am sure there are more situations like your vehicle and mine especially since as I read your description of what was happening and it sound like you were talking about my car. I appreciate any and all information you can give me. Please me email me at mbell033  yahoo.com Thank you
