are they interchangable between series?

 

as far as i know they have the same bell housings

 

yes, but S4 vs S5 trans mounts are different (atleast on TII)

 

so if i bought a s4 tranny would i be able to swap it to my s5? no im guessing? or can i mod it and then mount it on my s5?

 

i am not sure but you just might need to use S5 mount with S4 tranny and it will work

 

Yep, or so I've heard....

 

no you will need the s4 mount for the s4 tranny and s5 mount for a s5 tranny they cant be interchanged. me and a friend have run into that problem

Throwout bearings are different also.

 

I have swaped a S4 tranny into my S5 with no problem. Use the same mount the tranny came with.

 

 

thanks for the info!

 

Saw this thread and figured I'd also ask something along the lines of tranny and drivetrain parts. For TII's, could a S4 clutch be installed into an S5 tranny? The ACT clutch I got sitting at home waiting for install is out of an S4 tranny I beleive and will be going into my S5 tranny.

 

the clutch plates are different sizes on both NA and turbo to my knowledge, and I have also heard of many s5 tranny's going onto S4 cars, so i imagine it could be done either way. lates matt22

 

as long as its TII clutch to TII tranny and NA to NA it does not matter what series, atleast thats how it always worked for us....

 

i have an 88 N/A GXL and i put a 91 tranny in with NO PROBLEMS. i just bolted it right up, no fabrication need. And it took me a whole 2 1/2 hrs to do....easy swap and from what i heard the s5 trannies are better, that's why i did the swap
