G is the code for an automatic, doesn't specify which one.

If I have a 302 would it be a C4 or could it be a C6. Basically I'm trying to figure out what tranny I have. I always assumed it was a C4 but now I want to order a new torque converter so I have to be sure.

thanks

I thought they were all smallblock C6's by then but check the pan shape to be sure.

Thanks BBB. I crawled underneath last night and confirmed that it is a C4, (not a C6) thanks to the pictures that you directed me to. The cover is rectangular (with no notch) and there are 11 bolts holding it on.

Thanks for replying back!

Then they must have been all smallblock C6's starting in '73.

Another easy way to tell is if it has a removable bell it is a C4. If the bell is a molded part of the transmission it is C6

1961/78: The IDIOTS at FoMoCo used the G TRANS code for ALL A/T's. One had to know which trans was available with what engine.

1979: The IDIOTS finally woke up: G = C4 /// K = C6
