trans not shifting

[Cleaner13]

Ok recently I had my tranny rebuilt with Ck performance stage 2 stuff

I then went and picked my car up and drove about 40 miles on the parkway. No problems at all.

I had my car for sale and a guy came today to come pick it up. We went to go take a ride and the car didnt shift at all....

any idea why this happened?

first thing to do is contact the builder.then suspect a suck tv valve,tv upshift valve,governer or other mechanical problem.also if the trans still has the tv exhaust ball installed the cable could be disconnected.
