Oddly, the one that I fixed had an input shaft that took a few good
whacks to get out. Makes sure all fastenings are off, putt down some
padding, set the tranny on the flange for the rear cover, and whack it
with a plastic hammer.

Any thoughts on why the input shaft is being so stubborn?

If it shifted OK before, no need to reshim the shafts.
I repaired one just like you describe (hole punched through case)
last fall. Just tighten everything well, and it should work if it was
working. In your case, the nut on the aft end of the shaft may also
have been loose, causing the crunchy shifting. Take out the output
shaft and make damn sure you have the front, ccw tightening, nut
fully seated. Use red loctite on it and punch it thoroughly to
prevent loosening. Then shim the drum.

The long story as short as possible - last spring I bought my '74
disc Eldo Police and after a few miles the forward layshaft nut
chewed through the tranny case (last year). I tried the quick fix -
attaching a new nut through the chewed hole and sealing the hole up
with scrap aluminum and JB Weld - and the tranny made godawful
noises when shifting up from first as it transitioned neutral - so I
put it away.

Just getting around to starting the project now - so, using Pete
Ropers DIY article from guzzitech on shimming as a reference I
pulled the tranny apart today - and it all looks brand spanking new.
Nothing broken, no metal bits. The input shaft is not coming out,
even after a few taps. Before I go wailing on it, I thought I'd
check to see if there's something I missed - it feels like its still
"locked" in place - I removed the nut, tang washer and Boss. Also
interesting, I only found one hardened washer under the pegnut on
the speedo, not under the drive itself?

If anyone has any hints on what to look for, and reshimming the 3
shafts (not just the drum), certainly appreciated.

Thanks, -tom
