Hello I have a 1999 Jeep Grand Cherokee V8 4x4 limited and I have been having problems with it lately.

Recently my Jeep starting idling back and fourth between 500 and 700 rpms when I’m stopped at a red light and occasionally goes below 500 and starts shaking. Then when I’m at about 70mps on highway the Jeep starts kinda pulling me back suddenly. As if someone grabbed the Jeep from the back and started tugging it toward them. They’re very quick and sudden movements.

A few days ago I took it to mechanic and they couldn’t seem to find the problem, no codes, no check engine. They thought it was that the throttle body was not calibrated and they worked on that and said it should be good in a few days but it’s not.

Today I turned the key 3 times and it gave me a code P0751. If anyone could help me understand this issue I would really appreciate it. Thankyou so much

Figuring it was a trans problem more than fuel problem I found this:

Were you able to fix this problem? I have the same WJ 4.7 and I’m having the same issue.

Replace shift solenoid A. If it were me and while I was in the transmission I would replace the all, all being three of memory serves correct.
