Hello, the date and milage above is not actual date of first incident, but is the first time I took it in for the first oil change and vehicle inspection which also was the first time I complained to the dealership about the issue. My transmission slips between 2nd and 3rd gear at least 4 times a month. The dealer told me that if I cant prove it or if it doesnt do it when they drive it then they cant perform a diagnostic test to fix the problem. The seller who sold me the vehicle called me twice to see how im enjoying my truck and I complained to him both times about the issue and he told me the same thing about my issue. I even left voicemails to him about it and he never returned my calls until I made a year (3/16/14) owning my truck and claims he dont remember me telling him this the first time. Im a strong gm fan but I feel im not being helped with my issue and its annoying that I have to drive my truck cautious guessing will it slip this time or will it slip next time? if its professional grade then why am I having this problem? I use my truck for family vacations and I know anyone with the same problem would not drive this truck far away from home with this issue. It does it when it wants to but its just funny how im trying to figure out when it will do it again. I get all these emails asking me to rate the dealership 5 stars and to rate the truck but I cant even get my truck checked out. Then they tell me they wont give me a rental which I would need another truck as a rental. This is sad I spend 30 grand on a truck I cant get worked on unless I have proof.

We were on vacation in alabama and our 2006 GMC Sierra truck with 62,000 miles on it. When the transmission started to slip we pulled over and check the transmission fluid, it was fine. So we continued on until we got to the next town. Tillsman corner. We went to a transmission shop and they said that the transmission completely burnt up. We called GMC and they said that the warranty on the drive train was only 36,000 miles. When we brought the vehicle they were telling us it was 7 years, 70,000 miles on the drive train.

After driving over about 40 miles at highway speed the transmission will begin slippping in od. Rpm slowly climbs to about 3200 (normally 2100 at highway speed) with no change in vehicle speed, and eventually the 'transmission high temperature' warning appears on the dashboard display. Shifting to neutral and allowing the engine to idle for about 20 seconds and then returning to drive will temporarily clear the problem, but it sometimes returns.

Consumer complained about a couple of problems. One was transmission. While driving at various speeds gear slipped. When vehicle was taken to dealer for service mechanic determined that the cause was low oil. The other was for the steering column. When driving at various speeds vehicle knocked and squeaked intermittently. Steering column had to be replaced once before for same problem.

When returning from a trip the transmission started to slip when engaging overdirve. . Over the next 150 to 200 miles it progressively got worse and now overdirve and 3rd gear are entirely gone and the engine just freely revs. . Only 1st and 2nd gear are usable.
