Easiest way to determine year of C4?

there's a TON of different C4's, not only inside the mustang family, but other fords from the early 60's to mid 80's used the same transmission... with minor tweaks, different clutches, bellhousings, converters...

there should be a metal ID tag attached under one of the piston sidecover bolts, that a competent dealership or tranny shop can decode for you.

what's the code?

if it's a part number you can usually tell what year it is just from that . . .

There is a possible pitfall. My C4 has an early case with a late drum and input shaft. Meaning by the numbers on the case it needs an early TC, but my input shaft is larger and would never fit. I would be suprised if yours is like that, but it is possible.

The cars 400 miles away right now, so i'll revisit this thread in a few weeks. Where are these piston side-cover bolts (so i know where to look)?

Here, there's one on each side of the transmission. In this picture the stock gray steel cover has been replaced with a blue/purple bling-bling cover

This transmission is from a 1970 Ford Bronco, but it's still the same C4 tranny, just different bellhousing I think.
