i put in a TCI reverse manual valve body and now i dont have any gears. no reverse, 1234. nothin. i thought that it was installed right, but i guess not. what could cause this??

The little S clip that attaches the shift linkage to the shift valve probably fell off or wasn't connected.

Drop the oil pan and have a look.

yea im going to crack it open tomorrow and look at it, but I just doubt that it will be that simple. but hopefully it will be

throttle pressure regulator fell out, all is good now...
