Hi Peter – I agree with everything that David said.
A quick way to check the quality of the rebuild is to look at the ring gear attachment and verify that all the bolts are safety wired.
UPDATE: I see on page two of this thread that at least the bolts on the ring gear have holes on them for safety wiring. That's a good sign....
But in my opinion, right now you don't have a working transaxle. You need to figure out that problem, rather than holding on to the one you have just because it is a ZF. At the top level, yours seems to have problems that should make you very worried about what other issues might be inside.

P. S. I also agree with David that you should call up Roland, or maybe reach out to some of the German members for some advice. Good luck
