PEE-C is the ID Code for a 1967 C-4 tranny. Part Number reads C8ZP7000H. Hope this helps.

A 390 {S code} would have a C6. The C4, with a few rare exceptions, is a small block tranny.

A C4 will have a square pan and the C6 will have an "L" shaped pan.
A C4 will have a removable bellhousing.
The original automatic in an "S" code (390) Mustang will be C6.

I would say a C-6. The C-4 was for the most part used on small blocks & the C-6 on the big blocks.

well, if it is light, small and easy to pickup, its a C-4

If you get a hernia, slip three vertibrate and lose all bowl and bladder control while trying to lift it, it is most definately a C-6!

Fordfan,you are absolutely right the C-4 is 100lbs light while the C-6 is 145lbs heavy.(Without converter)And i think most of it is rotating weight.

Side note: There are several documented 67 and 68 "S" code and even a couple of "R" code Mustangs that were produced with C-4's. There was a fire at the C-6 plant in 1967 and with the majority of C-6's allocated to full size cars some big bock Mustangs and Cougars got HIPO C-4's with the Canadian FE bell housing. I owned an "X" code 68 Mustang with a factory C-4 in it. (wish I had it now )
