This is probably a simple question for most (but not me) I have a 68 coupe with a 302. I want to put new transmission lines in and change the transmission oil pan filter but don't know how to tell if I have a C4 or C6. Also, how many quarts does it usually hold when I refill it? Thanks, Scott

302 = small block = c4 tranny. just off the top of my head its around 8 quarts

A Ford C4 transmission holds 5 1/2 quarts of Type F ATF.

let's not ignore the fact that it could have been replaced by a PO with a c6, or maybe even some other type of auto tranny

It's easy to identify a C4. The pan will be square. The C6 will be in a big "L" shape.

You are correct sir, I was just mentioning that 'cause I don't think we resolved fully if the car does in fact has a c4 or c6

We can resolve that easily if sxs91 will tell us what shape the pan is on his tranny.

The 4 in C4 stands for 1964 the first model year of usage

The 6 in C6 stands for 1966 ditto the above

C4 Smaller engines three piece case 2 servo covers---- C6 Large engines 2 piece case 1 Servo cover

True dat! The C6 was used in big blocks starting in 1966. I seriously doubt he has a C6 behind that 302 unless some serious mods took place. But, we can't help him with the question until he tells us the shape of the pan.
