i have a 96 transam with a 6 speed. there is some weird noise when going from a complete stop. when i let the clutch out and give it gas the car kind of stumbles slightly. at first i thought it was the lsd going out or gears slipping in the rear. but if i rev the car slightly and give it some more gas, KINDA LIKE DUMPING THE CLUTCH AT A HIGHER RPM , the car just go's.
does anybody have any thoughts on what seems to be the problem .
either the clutch is going out or lsd going out or both.

 

A stumble isn't going to be related to the posi (LSD) unit. That would show up as a one wheel burnout at heavy throttle.

 

Sounds like you may have some clutch chatter.
