I just bought two Razo AT shifter for two different Civics. They are RA-89 and RA-93. I got the RA-89 on one of the car and it shifts, but after I shift back to PARK, the key can't come out of the ignition. I had to switch back to the stock shifter. I didn't get the chance to try the other shifter on the other car yet. Any idea what's wrong? Pls help! Thanks!
