Does anybody know if you have a EFI late model 5.0 donor Mustang that has a manual T-5 tranny in it and you put the motor with the computer and everything into a early Mustang that has a C4 automatic, will the computer and everything run ok, or do you have to run a manual tranny? THX everyone for your help!!

 

well i think it will run fine. it be best that if ur doing a efi converstion, go to mustangsplus.com they should help u out on how to wire etc.. give them a call they will most likely to help u out. but on my thought i think it would run fine.

 

Beware the balance issue of 50 vs 28 oz for your flexplate...
