this is a 1986 GXL n/a 5spd, going TII via, s4 TII engine, s5 TII tranny, custiom driveshaft that was used for a s4 TII tranny to s4 n/a diff TII swap(told shaft will work with s5 tranny to s4 diff though), microtech lt-8.



Ok..I got the crossmember stuff squared away. If I get a s5 TII tranny, I need the s5 TII crossmember. S4 or S5 TII tranny will bolt up to a s4 TII engine.



Un-answered questions are, if I use a s5 TII tranny, will the s4 TII flywheel, clutch, work. Also will my n/a 5spd hydrualics work (slave cyl.)? Last question is about the reverse gear and 5th gear switch, I read there different on the diff. series trannys. Is that just a matter of wires? I'm going to be running a Microtech LT-8, does that need the 5th gear switch, exactly what does that do? And if the reverse gear swtich is different, I assume thats just going to be a matter of extending wires maybe. Any help appreciated.

i dont know if this will help you, but i installed an 89 GTU tranny in my 88 GXL. Everything bolted up fine.



I only had one major problem, i used the stick (shift lever) that was stock in my car. The s4 and s5 have different lengths and one day it royally fucked **** up, so much so that i had to get the ****** new tranny basically rebuilt... Just a word of caution there...

Thats wierd...I bet the shifter length difference made it so when it was in gear, the shifter was still putting force to push the gear forward and it caused premature wear on the gears. The s4 and s5 do have different shifters, obviously you know that now https://www.nopistons.com/forums/pub...IR#>/smile.png, but the s4 n/a and TII have the same shifters.



I'm picking up the tranny on Wednesday, I hope it will bolt to my n/a 5sp subframe...but I've been told it won't, so I'll just have to find a s5 tii one.



Anybody else know about the other questions? 5spd switch and reverse switch?

Anybody else?

all you need is the reverse light switch, everything else should just drop right in

when i put my clutch in someone (how will remain nameless) order me the wrong (s4) slave cylinder and it didn't work. it wouldn't let the throughout fork sit all the way.

the clutch would just bearly ingauge and i burned the **** out of it luckily it was still in decent condition

chicken boy knows first hand N/A slave is different. i accidentally ordered the wrong one for him

Even the s5 TII tranny should bolt to my s4 n/a tranny crossmember? If so sweet..



And I'll remember that, I need a s5 TII slave..hehe.



Thanks guys.
