i did some looking but i havent found any threads on it, but if there please supply some links. I'll be looking for a new transmission pretty soon for my 86 GXL and i was wondering if i needed a new cluth and or pressure plate if i use an S5 transmission or will the clutch and pressure plate from the S4 will work with it. all info will be greatly appriciated. thanks

 

As long as it is a N/A tranny, S4 and S5 are completely compatible. Direct swap.

*edit* - unless its an auto.. then I think there are some differences in wiring and junk..but Ive never messed with an auto tranny so I dont know for sure.

 

The S4 and S5 trannys are wired up a bit different. It doesn't matter what kind of manual tranny. The only thing that will not work is a non turbo tranny on a turbo engine. It won't work because the turbo flywheel is bigger in diameter and won't fit in the non turbo bell housing.

 

make sure to get the s5 trans mount as well, its different than the s4 one

 

thank you all. i forgot to mention that they would both be NA 5 speeds.

 

yea i just did that with my turbo swap.. s5 TII tranny and engine in s4 car. How do I hook up all my wiring?

 

Im thinking bout doing this swap too. From NA auto to NA 5 speed. What kinda wirings are you guys talking bout.

 

neutral safety and reverse lights are all that need to be rewired. See "auto to manual transmission swap" or something like that in the archived section. Its the writeup i used for wiring, worked 100%.

 

i wont be doing this, i will be swaping two 5 speeds but just out of sheer curiosity how about cruise controle? do you need to rewire that also when you go from auto to 5 speed?
