Andy,

Has this always been an issue or is it fairly new? I agree with Mitch. If it is not going all the way into gear then it could pop out on deceleration. Check bushings and the adjustment by putting a proper drill bit throug the neutral hole in the shifter and check your adjustments. If it’s a Hurst shifter, also be sure the detent limiter bolt is not too tight since limits how far the lever pushes the fork.

LT1Vette,

I disagree on sending it back to the builder. We don’t even know if this is a recent problem or it has been happening all along. Why do you say with certainty that it is an internal issue? After 10k miles, lots can happen. If this has been happening for 10k miles, then lots of damage could have happened simply from having things out of adjustment this long. If it is a recent issue, it could be very simple. Calling the builder to troubleshoot may be an option though.
