64.5 coupe with 170 6 cylinder. Pretty sure it is a c4 behind it and the transmission is getting weak. Slips badly in first gear until it is good and warm. I am searching for a core that I can rebuild and am not sure what to look for. Are 6 cyl and V8 transmissions different ? Are there bolt patterns I need to watch for ? I have a line on a 6 cyl with automatic transmission out of a Comet but the guy doesn't know what year it was. Says it has been laying in his shop for 20 years, never got around to doing anything with it. How do I tell C3 from C4 ? Any other things I should look for ? Thanks so much for any insight.
Which transmission fits my coupe ?

the only differences between the V8 and six cylinder C4s are the number of clutches in each clutch pack in the trans. the six cylinder C4s can be upgraded to V8 specs if you want easily. also the accumulator piston is different as well. as far as i know the C3 never came behind the inline six.

There is a bellhousing bolt pattern difference between 1965 and 1966 though, which is why 66-68 200CI blocks are double pattern drilled:

This article is really about mtx bellhousings, but you can at least compare the different bolt patterns(mainly different up top) so you know what your bolt pattern SHOULD look like.
