My 2007 Yukon just had a total transmission failure with no warning. This is a vehicle that was maintained at the dealer for everything and in fact the transmission had been serviced recently. It has only 88,000 miles and has never been a tow vehicle. The dealer mechanic told me this is "to be expected" on this vehicle/model and that GM would not give me any help on paying for it. I am very disappointed since I come from a family that has only purchased GM products for my entire life. I will think twice now before purchasing a GM product.
My 2001 Yukon out of nowhere I stoped then took off my rpms would excelerate but it wouldn't pick up speed then I put in reverse it didn't work I turned it off for a few the turned back on reversed worked but when it warmed up it did it again dose anyone have a idea what to do
I posted this in the GMC Electrical issues forum but I'm curious if the source of some of these issues have been found. We have a 2007 Yukon Denali XL. When I come to a stop, my car often slips into neutral. When I try and go again, it either won't go, starts in a much higher gear, or it will start going and won't shift. I've had the transmission valve replaced last year after we had a stuck solenoid. This is only an issue at low speeds or start/stop. Sometimes it won't go into reverse or will be okay in reverse but won't shift into drive. It helps to turn it off and take the key out AND open the driver's door, then restart. The driver's door seems to trigger something that helps it reset.
I called our local GM dealership for an appointment and they told me it was a transmission issue. Since we had poor service from them last time, we opted to go elsewhere. We took it to a well known and reputable transmission shop who did a complete tear-down and they said the transmission is fine. They suspect it's an electrical issue. We are actually having a LOT of electrical issues with the vehicle. So I'm wondering if any of you with suspected transmission issues determined later it was an electrical problem? I can't get anyone at our local GM Dealership to answer or call back and the Chevy dealership can't get us in for a week. They also told us they'd never heard of this and we should just put in a new transmission. I don't want to spend $4000 (the quote for the new transmission) for it to be another issue altogether. Any suggestions? Thanks.
