Gearbox issues Alpine GTA

Looking to find out if anyone else has had similar issues and if they know the issue. My Alpine had an engine rebuild and is was on the dyno running the engine in. It was about 100k's in under mild load when the drive train locked up. The car can be pushed and the drive train locks and releases as it feels. Anyones thoughts would be much appreciated.

Hi There,

Not sure if it's too late to respond, but I had a similar issue with the gearbox on my R21 Quadra. Fresh back from a rebuild, it seized up.

I believe the only solution is to remove the transmission and have it looked at. In my case, the rebuilder admitted liability and redid the work.

You'll probably find that something major inside has failed. Sorry!
