1999 GMC Yukon V8 Four Wheel Drive Automatic 140000 miles
Hi - I'm hoping to find some help here. I have a 99 GMC Yukon that has a transmission problem. While getting onto the highway this morning, I was getting up to highway speed (65-70) when I heard a " pop" from under the truck. From then on, the ride seemed odd but I kept going (I was late for work!)
Once I got off the highway I noticed something else. When starting from a stop, the transmission seems to " miss" second gear - the engine revs to about 4000 RPM then I let off the accelerator, it will shift. Now I also noticed that it was also not going into overdrive.
When I got to work I was about to back into a parking spot when I put the transmission into reverse, it was acting like it was in neutral.
What is it and how expensive?
