Can anyone give me any info on if i would have to change out my clutch set for another? Im dont know if the input slines are the same on both trannys. Im swapping out my Tremec RTS 3speed +OD for a M5R2. Both Trannys came off a 4.9l.

 

I doubt it, but why would you put that POS in place of the lesser POS

 

The clutch should work with both transmissions. I kept the same clutch in my truck when I swapped from the RTS to a ZF.
