I made a two-part video series on installing an FC Turbo II TII transmission in an FB chassis. I just thought that it would make more sense to show others the process than to just draw pictures and expect people to know what to do.

TII shifter rod cut length: 30mm
Shifter tube cut length: 16.5-18mm
TII tail shaft with FB shifter housing

 

 

Don't forget to make another vid about the trans mount itself since that needs to be modded too

 

if its a S4 TII trans; the FB trans mount needs to be redrilled and a 3/4in spacer added.

S5 trans are considerably more complex to mount from what I understand, but I have no experience.

 

austin, i think you meant to say (in the 2nd video) to cut the tube 14mm (versus the 16mm u had cut) so the usable tube itself is longer.

 

great work. i learned quite a bit and it definitely was good to visualize the job in context. thank you.

 

Yep, I actually put S4 tailshaft housings on both my S5 T2 transmissions to make the swap easier. As you said, move the holes on the FB rubber mount closer together and either space the trans crossmember away from the body that ~3/4" or cut a notch out of the center of it and reweld it lower which is the route I took.

S5's are usable, but the mount surface is not flat like the FB/S4, it's angled so there's considerably more fab work needed. That is assuming you didn't want to solid mount the thing...

One other thing I'd like to point out - while what Austin did will work, there is a slightly better way to address the tube the shift rod goes in. There is a rubber seal on either end that should be retained to keep gear oil in (in the shitfer tower). It's better to cut a section out of the middle and weld it back together, that way you retain the seal on both sides. Some simple RTV though could probably work too. Just depends on how **** you want to get with these things (personally, I'm very haha)

 

interesting. I do not use a trans "mount/bushing" my trans is hard bolted to the cross member, with a 3/4in spacer lifting it up ( I believe this is Setzep's way as I remember, but dont hold me to that). As for the tube, I did as you have suggested, cut the area out of the middle to preserve the seals. All I did to seal it was stick both ends into some vinyl tubing I had laying around. Worked great.

 

Great video! I learned a lot from it. Question though, does this method also work for an SA? I have an S4 T2 tranny ready to go into my 79, but I'm not sure what route to take with my shifter location.

 

I found a video on youtube that shows one way of doing it. Should work for the 79.


This thread should be stickied

 

o i went whit the AUTO FC YOKE whit the GSL-SE driveshaft but the holes of both parts are different.

I buy the Universal Joint Moog 315G for the AUTO FC YOKE and don’t no what to do.

thanks
