Re: 1968 CY Trans details
 

I was told the 426 was a Julian date started Jan 1 of 68 so 426 was the end of Feb '69. I guess a bunch of guys possibly have CX tranny's with 427 build dates...very cool.

Jeff,

Here is my CX ID tag. Odd that yours is one below 427 and
mine is one below 396........ https://www.yenko.net/ubbthreads/imag...mlins/grin.gif

For the year 1970:
*TH400 CY Trans. was coded for the LS6 Chevelle,& Corvette LS5.
Higher-shift point and stronger bands & springs.I believe a thicker shaft as well?
*TH400 CW Trans. was coded for the L78 Chevelle-Nova-Camaro,& LT-1 Camaro-Nova.
*TH400 CR & CS Trans. was coded for the LS5 Chevelle-Monte Carlo,& Corvette w/Transitorizied Ignition.
*TH400 CF Trans. was coded for the L34 Chevelle-Camaro-Nova.
*TH400 CK Trans. was coded for the 300HP 350cid Corvette.

Would a 69 Chevelle SS L-78 be a CX code like the Camaro?

Re: CY & CX 400THM: differences & similarities
 

Yes,as they too had a higher shift point.

Thank you.

Re: 1968 CY Trans details
 

Couple questions>

1. What trans codes are correct for '69 COPOs with automatics? Are they different for different models i.e. Camaro and Nova?

2. In '69 are the CX and CY codes used on all solid lifter motors (with automatic trans)?

3. Do all TH400s in '69 have partial VINS stamped on them?

Thanks!
