hey i have a 2005 gto with a t56 has a one piece drive shaft that was installed before i bought it. when i get up to 80 mph it gets a bad vibration that feels like its coming from the rear. when it starts vibrating it also starts leaking trans fluid out of the tailshaft. if i keep it under 80 it wont leak. any suggestions here would be awesome

The one PC drive shaft, solution.... the OEM Two piece drive shaft or "Farbon Kiver" and new tail shaft seal.

Its had about 6 new seals the one that's in it now is from tremech

I had the same problem with my last GTO except it would blow the seal at 130+mph. I would put a hendrix 2 piece in.

would a bad tailshaft bushing cause it to have a vibration?

I'd make sure the Driveshaft is still in balance.
