Re: CY & CX 400THM: differences & similarities
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.

Re: CY & CX 400THM: differences & similarities
Chuck, the comparison is between the CX vs. the CY, not the CW version. The CW was used in the L78's, LT1's etc...

Re: CY & CX 400THM: differences & similarities
Ray Morrison sent me some more 400-THM info. It was an application chart for 1969, so I went ahead and ran it through Excel so it's easier to digest...

Re: 1968 CY Trans details
Here is a pic of the CW tag on my 1970 Nova L78. Where on the case is the VIN? I never looked for it and the tranny is back in the car. Had to post pic as an attachment.

Re: 1968 CY Trans details
I also have a CW trans in my 70 Z-28. I found the VIN stamped on the drivers side pan rail area recessed slightly. Did not see it until the exhaust pipe was removed. The stamp was at an angle when struck.
 reads 0L510574. Paul

Re: 1968 CY Trans details
The vin will be on the pan rail or the flange of the bellhousing.
