When I bought the Yukon 3 years ago the tranmission went out within months, they replaced it with a used one, now it is started to do the same thing, it will slip in and out of gear, when you give it gas it will jump into gear at an idle it will drop out of gear, it's been doing this every since they put the used one in, I noitied them they said that it is normal???? I had the work done @ pahrump valley auto plaza. I'm afraid that when im at a light it will not go into gear and I will get hit. No waring lamps came on at all, it has progressively gotten worse.
Driving on the highway the vehicle would not shift gears causing the driver to proceed well under the posted speed limit. The driver attempted to increase speed slowly and the vehicle hesitated, the engine rever but the speed would not increase. This caused cars at the correct speed to veer out of the lane to avoid a crash. Once off the highway the vehicle was hesitant to shift gears and emitted loud revving sounds from the engine. Proceeding from a stop at a red light the vehicle hesitated movement causing the wheels to spin on the pavement and again cars to veer quickly out of the path.
