Drivetrain C4 Fun! Reversing While In The Park Position.

  1. Help! I installed a c4 and swapped the green dot vb to a 67 vb. While in the park position the tranny goes into reverse. I thought it was a linkage issue but while disconnected I put it into park by hand and it still jumps into reverse. I'm guessing I installed the vb wrong? Any advice would be awesome!
  2. Is there a reverse solenoid? Is it getting power?
  3. Sounds like what my C4 has been doing for the last 20 years. When it locks into park it is solidly in park, but a lot of times if you push it up into park it doesn't quite get into park and can - when you let go - slip into reverse. If the car is rolling very slightly when you push it into reverse it will lock in everytime - or even sticking your foot out and rolling the car an inch or 2 while holding the selector in park.

    Sorry, I don't have a cause or a solution for you. Well, I guess I do - I just swapped the C4 out for a T5. Problem solved!
