Transmission wont shift

[1951D47U]

Traded for a M2 that had been used and abused last March.  Got it running Saturday Sept 21, and that is the good news.  Can't get her into gear.  Took the top off the tranny and then watched the shifter arms.  When shifting to reverse it also moves first gear forks to engage first gear.  I assume they are using first gear and running it off the reverse counter shaft to get reverse.  Problem is when I go to shift to first it still moves arm to reverse counter shaft, just as if I was shifting to reverse.  Can't get it to shift to second at all because arm tries to move reverse lever and there just ain't no room in shifter housing for that.  My guess is when shifting to first the reverse arm should not be moving?  Any experience with this problem?
All of this is taking place with the shifter off of the tranny.  The tranny itself will work in every gear by using a screw driver to manually move the syncros or the reverse counter shaft for reverse. The whole problem is in the shifter.  Also one hell of a time getting the top back on and having the reverse arm slip in to its hole, but it can be done if the right words are muttered under your breath.

I find the double wheels on the front interesting, how was it done? sorry cant help with tranny issues 

[1951D47U]

The double wheels are done just like the duals on any deuce.  Inner lug nut screws over bolt and holds on inner wheel, has threads on outside that are larger for the second lug nut to hold on the second wheel.  This old girl was being used at a sand pit so it was very sandy and I'm sure that helped flotation and traction.  Problem with this whole setup is when you turn the outside wheel hits the fender, hence the lip on my fenders is partially torched off.

You might try to disassemble the shift tower and stick and see if my it's bent. Also take a good look at the idler gear for reverse. That was the weak sister in the tranny's. Also the the reverse slider gear they have been known to break.

The manual has a view of the transmission.

Don,
Where in the manual is the picture of the transmission?  All I have been able to find is how to remove and how to replace but no exploded picture of transmission or shift tower.  Or which manual are you referring to?  I have one I down loaded that appears to be the government one. 
Actually the transmission seems to work it is just getting the shift tower to put it in gear that is the problem.  Nice to know that reverse was the weak point.  Mental note to self: take it easy in reverse.
Thanks for the response.

There are a couple of different manuals, TM9-1710 is the one you want. Try this link:

Hope this helps!

1949D23J just thought I'd throw that in!

[1951D47U]

Thanks, that manual looks like just what I need for some good reading tonight.
My son has had his eye out for a D2.  We need a radiator for our D4.  Probably going to gerryrig an automotive one in place till something comes along.
Thanks again.

 :)There is good news and then there is not so good news on the shifter problem.  First the good news.  Thanks to spec4don and the manual download I believe I have it figured out.  The reverse bracket is suppose to slide freely on the shaft until the shift lever pushes the plunger in moving the ball, part M, into the slot on the rod locking the bracket to the rod and shifting the reverse fork.  Said ball, part M, is stuck into the slot, probably rusted, causing the reverse bracket to always move when it is suppose to be sliding freely on the shaft.  Problem diagnosed.  Now the not so good news.  To fix one should dismantle the reverse bracket by sliding out the shaft and clean the ball, however, since the ball is stuck locking the bracket to the shaft one cannot slide the shaft out to release the reverse bracket.  Catch 22.  So I am soaking it in rust penetrator and oil and hoping it frees up.  Tune in tomorrow for the continuing adventures of 1951D47U and the case of the stuck shifter.

[spec4don]

You probably already thought of this but maybe throw a little heat to it. Then hit it with the penetrating  oil again.

Well it turns out that the detent button for reverse that I imagined was stuck on the shaft due to a rusted detent ball was just ever so slightly out of adjustment.  There is a castle nut on the end that you put a cotter key thru to hold in position.  Who ever was there last had the nut just past the cotter key, so the key would keep the nut from coming off but not from rotating from vibration and moving slightly out of position if the nut turned.  I managed to drive the bracket off of the shaft and then it became apparent what the problem was.  Easy fix putting said castle nut back to where the cotter key keeps it from moving out of position and the whole transmission works, a little rough to shift but that is to be expected considering the water in the bottom and a little rust here and there.  Put two gallons of diesel in and run it around the yard, flushed, looks watery and rusty, put in two more gallons of diesel and run it around the yard, and flushed, better looking than first flush.  Put in some 80/90 and doing much better now.  All gears work though I wouldn't say this is anything like a smooth shifting transmission, maybe just the nature of the beast, or maybe it will loosen up with use.
Best news is the engine doesn't smoke, I was worried I might have a tracked mosquito fogger on my hands but such is not the case.  Need to get it to idle better but it runs good once you come off idle.
