Re: 69 Nova L78 TH400
 

Mark, do you have a breakdown between the L-34 and L-78 production for the TH400. There was supposed to be a difference in the high horse trans, I wonder if the code or ID tag was diffrent. Any thoughts....???

In '68 the L-78 auto was coded CY, in '69 CX. I think Rob has posted elsewhere on here the internal differences between these transmissions and the ones going in the lower HP cars.

Here's a thread with the different parts that the CX & CY tranny carried in 1969...I've got an application code table somewhere, maybe I need to post it also...

Re: 69 Nova L78 TH400
 

Now I remember seeing that thread the first time. Good info! So what is the difference between the 70 version with the CW code? Are they built to the same specs as the CY version?
