Not fully locking in to park
 

Hey my transmission recently stopped working got a second hand one installed runs fine but when I go to turn off my car I pop it into park and turn off the ignition but it sometimes won’t let me turn to the lock position to get the key out then I turn the electronics back on and shift through the gears and back into park sometimes a few times till I can fully turn off and get the key out it’s like it’s not locking in to park. anyone else have this problem of know what it might be??
