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!
