Four problems related to transmission gear slipping have been reported for the 2007 Chevrolet Suburban. The most recently reported issues are listed below.
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 revving. 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.
