Transmission shifting problem

#1

Post by white1j0 » Wed Oct 18, 2017 9:19 pm

I had my transmission rebuilt, when I got it back I had to flip the shifting lever on the lid to the up position, beings it for a "47 and the shift pattern is reversed, it was originally set up for an earlier '41 to '46, all parts are installed correctly and the timing marks are correct, I finally took it out for a road test today and it shifts into 1st, 2nd, but when you hit 3rd it grinds and wont go, I tried adjusting the shift rod but didn't help, I put it up on the stand and turned the rear wheel while in 3rd gear position and it felt like a chain skipping over a tooth on a sprocket any suggestions would be greatly appreciated.

Shifter arm for a '47 points down, not up. The early ones are up '36-'46. Are you sure the right drum is in it? 4 speed type and not 3&R?

Remove primary cover, clutch disks, put a mark on tranny input nut and sprocket.
Count turns of tranny shaft to rotate sprocket one turn for each gear and report back here.
1st is forward for 36 to 46, two large screws hold shift gate to tank, tranny lever points up.
4th is forward for 47, two small bolts (hidden) hold gate to tank, tranny lever points down.

Sorry my mistake, the lever was pointing up and I had to switch it to pointing down, I forgot which way I switched it beings I originally went by Bruce Palmers book which calls for it to be in the up position for '47

Pop the cover off and inspect the drum make sure you have the correct drum in there. make sure your 3rd and 4th gear main shaft dog is in correct.
