Need A833 advice
IMO; yur doing the right thing.

That's pretty fast! I've got a lift, but no air tools and no trannie jack. It will take me longer, even without the GV overdrive.
I'm the builder. The M/S bearing is a standard 307, and on this trans it's held on the M/S with a snug snap ring (and I installed it myself), and on the front side is held in place with the the ring on the inside bore of the tailhousing. I don't see any room for movement there, especially on the M/S itself.
The synchro clusters were assembled properly; I was very careful and took my time. Of course, something could have gone wrong since then, but I doubt it.
I might be mis-reading your last sentence, but If I'm not, I believe it to be wrong. As long as the engine is running and the clutch is engaged, all of the gears will be spinning in a constant direction, whether the car is moving forwards, backwards, or stopped in neutral. The input gear and the M/S gears will all turn in the same direction as the engine, and the counter-shaft will spin in the opposite direction.
So that takes me back to my previous question - when in 2nd, 3rd, and 4th gears, will the M/S be spinning faster than first gear is, or slower? If the M/S is spinning slower, then my trans will be good as-is. If not, I think my only option is to pull it apart...
