Shifting problems

Please help!!! I have a 2002 Monte Carlo LS. Have replaced the transmission with one from a junkyard. I put all new Solenoids in it and it worked great first test drive. The next time I drove it it would only go to second gear. I took the transmission back out and went back to the junkyard and got another one, keeping my new solenoids. Same thing again!!! I just ordered a new preprogrammed pcm. Again it shifts fine the first test drive but when I turn the switch off and crank the car back up it won’t shift passed second until I take the battery cable loose for a while. Anyone have any ideals
