This is usually a result of a misadjusted shifter coupler. A common symptom with 901 transmissions. Remove the coupler plate. Place your shifter in the neutral position, loosen the coupler clamp bolt, and move the shifter towards the driver all the way while still in the neutral position. Then move the shifter all the way to the right while still in neutral. Tighten the coupler clamp bolt and then go thru all the gears while standing still. If everything feels like it should, road test your vehicle and see if you have eliminated the grinding noise. Take your wrenches with you on the road test, so you can fine tune it with the coupler while your on the road. It took me three tries and 10 minutes before I got mine just right. Hope this helps.
Thanks very much. I figured it's still a coupler adjustment issue. That would make perfect sense as this morning it did it bad on a 1st to 2nd up change. It sounded like it was grinding against a gear travelling at a vastly different speed. If I am indeed snagging reverse gear, I suppose that would indicate the clamp is adjusted too far towards reverse (the drivers side) yeah?

I've done the drive around with the spanners making adjustments, but I've been stabbing in the dark to a degree. I did have trouble engaging 4th and 5th, but I seem to have fixed that. I'd say I must be close.

If I change really really slowly (like you would in a car with no syncro), I can usually engage 2nd on the up and down change.

Are your engine/transmission mounts in good condition?

Check your clutch cable adjustment for correct end play.
Thanks, I'm glad I don't have to worry about that, just the rotation.

Engine and trans mounts appear fine.

I've yet to check the clutch, but will.
