this is my sister's car. i messed it up. i had a shifter that i was going to put on my sisters 01 celica auto. i tried to install it but it would not work correctly. so i put the stock one back on and i can't get the key to go into the lock position so i can pull it out unless i unscrew the shifter and pull up on it a little until i hear the lock click. also sometimes i can't get the but to depress when i try to get it out of park. is there some sort of adjustment. all i did was take the knob off install another and then reinstall the stock part. i didn't mess with anything else. i thought but just tightening the 2 screws down on the knob that it would work fine. anybody know what is wrong here. thanks.
