Need An Upgrade Tranny SL6

you could find a later 904/999 out of a 318/360 car and use the internal guts to upgrade your trans.

i would guess that 904 in front of /s only has 3 clutch disc in front and rear clutch paks...

upgrading to a 904 from 318 would have 4 and 4 disc

yea that would be better! so how much later like early 70's later? ans also what about a truck tranny guts?
