just reinstalled the tranny and now there is vibrations when i accelerate and at rpms above 3gs. i have a feelin it may be the universal joints on the driveshaft or the driveshaft has 8 bolt holes and the rearend only has 4 to connect it to could it be off a hole?
thanks gary

well i don't know.. but i'm having kind of the same problem but i feel the vibration or... better yet, the resistance on the gas pedal passed 3k... But i didn't put a new tranny in.. i put a new motor in.. but i'll be checkin in on this post to see what others think

tranny in my cars not new i just had a clicking problem so i dropped it to check out another problem i had. its gotta be something to do with the driveshaft because it didnt vibrate b4 i dropped the tranny.

ok my guess... either your driveshaft is outa alignment(maybe slightly, and i mean slightly bent), a bad u joint, maybe something off balance... or that new trans has something a lil off internally... also... mighta mounted the trans a lil off, not perfectly... just a lil would do that to ya id wanna think...

ya it was the same trans as b4 i had a clutch fork problem but fixed it. so the same trans was mounted in the same location... where would the driveshaft come unbalanceed?

did you mark the driveshaft and make sure it went back in EXACTLY how it came out?
you may have it flipped 180* over.

GaryBisiniere

do you mean how it connects to the rearend is off? 180?
