So I've recently purchased a 97 GT with 160k for $1500 and haven't really had any problems with it that weren't an easy fix. While driving the trams seems to slip or shutter a little and it only happens after the motor and trams warms up while driving for some time. I've checks the fluid and it was a quart low so I added a bottle of Lucas hoping it help it out and or hopefully fix it. It still does it but not as bad ,but regardless it's still happening. It seems to be happening from 2nd to 3rd or maybe going into over drive?
Thoughts on What could be the problem ?
