CY & CX 400THM: differences & similarities

**mockingbird812** · #1 02-13-2009, 09:08 PM

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!

Can anyone tell me what the application for a TH400 with a 71-CA on the tag is?

Thanks
