i have a 86 245, not a 700, but the problem is after the aw70 tranny swap.

no problems with switching them out. for the replacement tranny, i replace just about all the seals, etc.

i replaced the original tranny with a 92 tranny. no leaks.

one issue, i accidentally pushed the replacement tranny off the tranny jack and it fell on it's side but <12 inches.

problem:
a noticeable vibration gets worse at about 2200 rpm's after the car warms up. it does this at idle and hwy driving (about 65-70 mph is about 2200 rpm).

i have good motor mounts, new tranny mount. no driveshaft issues because the car does the vibrating at idle.

the tranny changes gear just fine.

any suggestions very much appreciated.

thanks,
