Since they are that bad, personally, I'd take that shifter off and put the stock one back on it so your Pro 5.0 doesn't "disappear". Why did they wash the car?
I had mine in for a lower intake recall and when I went to pick it up that night the driver's side door lock was broke and they didn't even have the TPS plugged in.
