I am swapping out the transmission on my 122. I bought a used one, and the only difference that I can see is the shifting lever. They are both 3 speed. The used one came from a 70 I think, seemed to bolt right on. Now when I let the clutch out, everything locks. It turns free with the clutch in. Throw out bearing seems fine. Anyone else had this issue? The problem seems to be in the clutch shaft.

What model are you working on?
Did you use all of your original parts except the rear end ?

Does the clutch shaft and transmission turn free with the clutch disengaged for several revolutions or just for one or two?  Takes a bit of turning to get them trannies to turn the wheels.  Might be something inside that is binding after a load on the gears is taken up.  Clutch shaft and transmission are the same in a 70 and a 122.  As you noted the shift lever is different but you can unbolt them and swap one for the other as they are the same inside the transmission.  Maybe the forks are not aligned right under the shift lever.  Could be locked in two gears.

The transmission turns free. The engine turns, but only with the clutch in. I am thinking a roll pin, or something is catching somewhere. I made sure the forks and shift lever lined up, and I moved them with the shifting lever off. The transmission is not the problem. Just can't figure out what is catching. Anyway, I will start to look again in a few days.
