So I just got done with my Whipple swap. I have not touched the drivetrain whatsover and only moved the clutch cable out of the way to install my valve covers. I go to pull the car out of the garage and it will not go in reverse at all. I wondered maybe cause the idle speed is high at first but once it dropped down to 900 or so it's like hitting a wall with the shifter. My only guess is I maybe screwed something up under the dash when I had to unbolt the hyrdroboost but the only electrical plug that was disconnected was the brake light switch. Is there a reverse lockout switch under there? The car goes into all other gears fine. The car sat for 5 monthes and all of a sudden this pops up. I'm stumped :shrug:
