I think the passages cast into the case in the valve body area are different in 64 vs 65 and later. I have a bare 65 case I can take pictures of if you want to compare
Thanks, I have a few cores myself. Studying my books and service manuals it looks possible. I don't want to lead anyone a stray. If someone has tried this before and it doesn't work I would like to learn from their experience.
I have always heard that the 64 was stand alone different in a number of ways that make it incompatible with later valve bodies and other parts.
Getting back Did you get a chance to try this transmission out before you installed it? I rebuilt the 65 trans I put in my 64 before installing. While the fluid didn't look bad there was quite a bit of rust in the valve body. Something to think about. Ken
kind of like , everybody thinks the trans that was behind the 300 engine is a power glide because it was a 2 speed.... but it aint....
The '64 TH400 (Super Turbine 400) has a one-year valve body...for a "400" A similar valve body was used in the TH425 front-drive variant, and those were switch-pitch in '66 and '67 model year. A shift kit for a 425 works in a '64 400. IF (big IF) the case of the '64 has the proper drillings, it should be possible to convert it to switch-pitch. I don't know if the case is compatible.
