Make sure you have the power plug usually green or grey plugged in, the neutral safety switch plugged in and did you turn the converter until it locked in 3 times
Double check and if all else fails you have a bad tranny

does it have rear drum brakes that may have locked up while you replaced the tranny ?
Also make sure its the tranny for the model year truck you have it in because some chevy transmissions are stand-alone for certain years only 92-94,95 only, 96-97,98 only,99-03,04-09
