Hi everybody,
Recently swap my SC400 auto trans with T56 on my boosted M90 with E420C and my only problem is driveshaft vibration in the first gear,
just few seconds after releasing clutch. In the all others gears and high speed are ok. Looks like when driveshaft start rotation in the first gear it bents driveshaft and make high pressure on rubber support.
Initially I have problems with: loose driveshaft support, driveshaft support adjustment - add spacers, replace 4Runner trans mount with TransAm ones - now much better shifting, send to driveshaft shop to double check modification, balance again (two parts balanced together) - no problems, check driveshaft support bearing and rubber - no problem found.
Trans and Driveshaft shops suggested driveshaft support rubber piece to be replace with polyurethane.
I guess my questions are, Is it problem with driveshaft support only ? Something else to be checked ?
How easy is to replace driveshaft support ? Who can make driveshaft support rubber piece from polyurethane ?
Any other idea ? Thanks.
