The check engine light would come on and the car would jerk at high speeds on the freeway, it even powered down completely on the freeway after reaching a high of 65pmh. The car would make strange grinding noises and lose power steering also. The vehicle was brought to the Jeep dealership and diagnosed finally after 2 visits as a faulty shifter module/control module or the cars "computer".
I began to get a whining noise from the transmission. I brought the car in for service and recommendation were to service the transmission and the noise went away. Just recently the whining noise returned and now when shifting from first gear into second it is a hard shift not fluid and smooth. The service station who I have been going to for over 30 years is a very reputable and a life long friend. He found no codes from the on board computer and his recommendations were to have the car checked by and Jeep dealer for more complete diagnoses as they have equipment that might help with the problem but his diagnosis was probable bad transmission. From the start this car always had a shift problem from first to second. Many times there was a delay in from park to drive and had brought the car in for service while under warranty but was told there were no codes nor anything wrong with the transmission. I have been told by my mechanic the Jeeps are known for bad transmission but never got any service calls.
