if you change the bell housing will this trans fit a GS4? what mods will I have to do to make it work? what about the trans computer? any info is greatly appreciated!

 

I think it does. MVP sells an adapter plate for the supra transmission and the GS V8 engine. You may want to contact Kevin @ MVP.

sorry I was talking about the auto trans!

 

Why would you want a auto tt trans? Most auto tt owners upgrade to the th400 or the 6spd.
That plate should work to swap auto, 5 or 6sp for that matter in the 1uzfe.

 

Supra trans is a four speed, Gs trans is a 5 speed. Your shifting gate will be off and you will probably run into shifting issues due to the fact the car is trying to shift through a different tranny. Physically it will fit without any changes.

Edit: After re-reading this I may have not responded with what you were asking, sorry about that.

 

hehe.. interesting post.
