I have a 91 cherokee laredo, 4.0 6 cylinder. I went to pull out of my driveway yesterday morning, and it would not go into gear. automatic transmission, but now the rpms are going way up to make it shift, and when it does it shifts hard. it has come out of gear while i was driving twice, and im not sure what to do. i replaced the tps a few months ago, so i know that that is not the problem. Also, i was wondering if anyone knew how to bypass the stereo amp under my rear seat. i have powered speakers, and they only work intermittantly while the amp is hooked up. thanks.

 

as with any transmission issue, the first two thing I would check no matter what are:

fluid level/condition
TV cable adjustment

 

Would you do that before or after you fixed the stereo?
