I had a C-4 and built it up with normal stuff Shift kit from transco, all new internals with a rebuilt pump. Its a Truck style C-4, problem is I sold it and went with a T-5 in my car instead. I origionally built it for a bracket race trans. But it retains the auto valve body but just has a shift kit.

The guy who bought it is telling me it wont fit! WTFEer!!! What all does he need to install this trans to engine. here is what I think but I cant remember some tooth counts etc.

sheild between engine
torque convertor
flex plate from an AOD
automatic Starter
remove pilot bearing from crankshaft
T-5 cross member and trans mount will work

questions are ..........
what is tooth count of AOD flex plate?
what is difference in AOD starter and T-5 starter?
what is bolt pattern on torque convertor to AOD flex plate (seems I remember it taking some special convertor........is this true or does the one that fits the AOD bolt right up to the AOD flex plate?

thanks for any light you can shed on this subject!
Jack
