Just purchased an 89 GTUs with a bad motor. Want to know if a Series 5 TII motor would bolt up to the GTUs tranny, or would I have to use the TII tranny and a custom driveshaft. According to this website the GTUs and TII tranny are the same but with a different 5th gear. http://beyondtheredline.fd3s.net/GTUs.html

Also, how difficult would be to wire this up if I got the wiring harness with it. Shouldn't it be pretty much plug and play?

 

just did that this weekend. the motor will bolt right up to the tranny the t2 harness plugs right into the car and that all works. the website is wrong the trannies are different

don't wreck a GTUs!

 

too late

 

Mike,

Thanks for the info. So, as far as wiring is concerned, I don't have to cut and splice any wires, just plug and play?





Vosko,

Sorry I've commited myself already. I bought a complete Series 5 motor, tranny, AFM, wiring, etc.
