Transmission, stock 3 speed, rebuilt, and adjusted. Took the truck out for the a first run and the transmission runs fine but at some point the shift becomes jammed when down shift at a stop, to the point I have to get out and move the 2/3 gear linkage to neutral whereupon I am able to shift it again. Later at some point it will jam again and I have to do the same. What is the problem, is it linkage adjustment, either under the hood or the column or something else? Thanks for your help
God bless,
Dave
