 On two occasions an error message that read service 4 wheel drive appeared on the display. i mentioned this to the service department while there for an oil change, and was told that everything checked out okay, and that i should drive the vehicle in 2wd, not auto. also, i have been having a transmission slippage issue that started between 50,000 miles and 58,000 miles and was very sporadic. when starting from a dead stop (stop light for example), the transmission wouldn't engage as i pressed the accelerator. after 10 to 15 seconds of pressing my foot on the accelerator, the transmission would finally engage and the vehicle would move slowly with the engine reving. i mention this to the dealer when the vehicle has approximately 58,000 miles and i'm told that they will need to keep the vehicle for a few hours and there is a cost of $120 plus tax to perform diagnostic testing. as my schedule did not allow for this that day, i left. the problem was very sporadic at this point. at 63,000 miles i am driving over a mountain pass and the display reads something along the lines of transmission overheating. i pull off the road and wait for it to cool, then make my way home. i entire trip home the transmission is slipping between all gears and shifting hard in the higher gears. i take it into the dealer for diagnostics the next business day and i'm told that i need a new transmission. i am advised by the dealer that there is no external cause for this failure and the inner mechanism of the transmission has fallen apart and cannot be repaired. my powertrain warranty ended 6 months ago, so i face a $3,350 bill for this repair. after i complain to gm customer assistance, they agree to pay 30% of the repair and 5 days of the rental car, but i feel they should pay the entire amount.

 Third incident for this problem. while driving in (d) the transmission will disengage and the vehicle engine will rev up (3rd & 2nd gear) seem to work still. this has happened at various speeds from 25 to 55 mile per hour. only one time has it been close to an accident while making a left hand turn with on coming traffic. the dealer has made inspections of the transmission once, the second time the dealership was unable to duplicate the problem after keeping the vehicle more than 5 days. the suggestion from the dealership manager was to wait for it to happen again, place the vehicle in either 3rd or 2nd gear drive it to the dealership leaving it in 3rd or 2nd gear applying the parking brake so that the manager and a mechanic can get into the vehicle and test what's wrong. the 3rd time this has happened it was around 8:30 p.m. and we were unable to take it in to be examined. this problem if it happens again while making a turn or at anytime with oncoming traffic could cause a serious accident. *cn

 Tl*the contact owns a 2007 chevrolet suburban. shortly after the vehicle received a transmission flush, it would not move forward in the drive position after being placed into reverse. the following day, the contact took the vehicle to the dealer and they replaced three plates, a valve, filter kit, and a gasket kit. the vehicle was repaired, but the failure recurred less than a year later after another transmission flush was performed. while driving 65 mph, the vehicle began to hesitate and the engine revved, but the vehicle was losing speed. she drove to a repair shop and the mechanic stated that the transmission was not shifting past first gear. the contact took the vehicle back to the dealer that performed the original repair, but they stated that it was no longer under warranty and was not their responsibility. through online research, the contact found numerous complaints about this same defect. she believes that a recall should be issued. the failure mileage was 65,414 and current mileage was 123,000.
