I got a spare tm420 to use while rebuilding my original.
But the rear bearing retainer (tailpiece) was broken and removed. After removal, the mainshaft assembly seems to have shifted to the rear. I now see some roller bearings loose in the case.
Assuming these fell out of the clutch gear assembly, is there a way to sneak them back in without complete disassembly?

I believe it's possible to pull the front bearing retainer and input shaft, and pack the bearing rollers into the back of the input. I don't remember if the cluster gear has to be dropped down into the case or not to allow the input to come out!

OK, that cutout section of the symchronizer area isn't there on some of the passenger car transmissions I've worked- - - -won't clear the cluster gear teeth without that feature!

The main drive shaft will come out on a 420. On a SM465 you have to drop the Cluster gear down.
