Got this manual valve body with a race car but am trying to find out the manufacturer of both the valve body and transbrake, and if it is reverse or forward pattern. I've looked through my catalogs but can't find anything quite like it - especially the solenoid for the transbrake. Figuring the orange transfer plate should be a dead giveaway to someone who has had one. There's also a "JC" and "8302" hand stamped along the edge of the valve body.

If it's any help the trans is a 1976 440 High Performance (cop car).
Any ideas? Thanks in advance ...
