Problem with 915 trans. Need Help/Suggestions
 

Looking for some suggestions and guidance.

Over the weekend I was on track with my 86 Carrera. On what would be my last lap on track, I was attempting to shift from 2nd to 3rd and the transmission locked up in 2nd gear. Clutch still works so I was able to trailer the car home. I can't shift out of 2nd so I have no reverse(or any other gear).

Car has approximately 130,000 miles and for the past few years has been strictly a track vehicle. To my knowledge the transmission has never been out of the car. Over the past few years, to improve shifting I've added a WEVO shifter and the WEVO PSJ coupler. I've added Tarrett solid motor mounts as well. Prior to the lockup on Sunday, I've had very few issues with the transmission.

Any ideas/opinions on what might have broken?

Thanks in advance for any advice.

Remove the shift fork plate and take a peek inside. The fork attaching bolts have a tendency to loosen over time. You'll know if they are the problem as soon as you take the cover off.

If that isn't the problem, opening it up is the only way to know for sure.

This is a strange sympyom, and because I'm not familiar with your after market components I think that I'd start with those. After that, the shift fork plate, and...
