John Deere 60 lose trany when shifting

[1tinkerman]

Model 60 here. Loose the transmission when crossing from one range to the other. Get it back by going to the other range and then coming back. Sometimes it take a few times before I get any gears again. Is this a simple fix or a serious task??

I remember that dad had the same problem with an old B, didn't do it all the time, but was really frustrating when it acted up. I remember we took the shifter plate off and shimmed between the ball on the shift lever and the top plate, in effect making the bottom end of the shift lever extend further into the shift forks. My memory is really foggy, but I think we took a washer and dished it to fit the contour of the ball shape of the shift lever and put it between the ball and the top plate. If the 60 is different and this makes no sense, I understand. You just jogged my memory with the description of your problem.
