Allis 312 Transmission won't do 3rd

My '71 Allis Chalmers 312 Ser.#15302358 garden tractor works fine in all gears except 3rd. It will not stay in 3rd. It feels like it goes about halfway in then jumps out. Any tips without completely rebuilding the tranny?
 
Thanks Bret. I have the official 130 page Allis Chalmers Service Manual for Model 300 & 400 Lawn & Garden tractors. It has nothing about adjusting the 3 speed transmission linkage or any other that might apply. Is there another manual you are suggesting?
 

I'll try to remember to look in mine. You can also try this site- http://simpletractors.com/club2/default.asp
