Is My Trans Done?

[MyCARneedsHelp]

Well my car has bout 170k on it and the motor is rebuilt and i thought maybe i would beef up the trans and installed a B & M Shift Kit. It worked great for a day and now it doesnt shift into 3rd gear. 1is and 2nd shift great. Reverse is good. It acts like the car goes in Neutral i checked the fluids and replaced the gaskets to try again and it still doesnt shift. Any ideas? Do i need a new throttle body? - Thanx Guys

Do i need a new throttle body?

Drop the pan and see if any of the solonoids got knocked loose or the wires fell off them. Then if that doesn't work I would put it back the way it was and be sure no particals got in the valve body. Usually you would experience some slipping before it completly gave out. Some tranny shops can test the solonoids for operation.

Lets hope it isn't the tranny.
