hey guys replaced the govner pressure solonoid in the trans, she shifts again! now i got a P1740 code. guy at autozone said its trans something or another

what would cause it?

 

P1740 is a TCC or O/D Solenoid Performance

double check everything and make sure everything got plugged back in....also, try resetting the computer and see if it comes back or any other codes come up...if you didn't reset the comp after you replaced the gov press solenoid
