Hello, thank-you.

Re: CY & CX 400THM: differences & similarities
 

Does anyone have photos front and back of an original T400 6 lug convertor. Just came across one someone wrote GM 70 on seeing if it matches up. Thanks, Larry.

Here is what I have...this is from a 1970 Nova CW TH400...original 6 lug convertor.
Hope that helps...wilma

Hello, thank-you for the photos. Mine does not look like that so probably isn't GM. By the way your PM box is full tried answering that way. Larry

What would the Pontiac version of this trans be. I have a 68 PX would it be equivilant to the CX. Thanks, Larry. 520-349-2337

Anyone know what a CY dated 1977 is from? Would this be a service unit?

CY coded TH400...
 

Last reference I see in Colvin's book is 1974...perhaps you have a service unit??

A service Trans with notate that it is.
Look around the bellhousing for stampings like CT 123456
