1946 sedan gets stuck in gear

the man

Junior Member
so ive been working on this 1946 sedan that's been stored 40ish years. went through everything and got it running. however the trans is acting up. it keepd getting stuck in gear. i can disconnect the linkage and move the **** arm freely. seems to be ok. i can move the levers (once i get them un stuck freely. reconnect it all, shift in to reverse and back up. but pops out of gear. i need to hold it into place. drop into 1st, goes forward then i cant move it after that. i need to redisconnect and pop it back into neutral and then it seems fine. any ideas. or directions on how to adjust the links?
 
It obviously needs a rebuild. But in the meantime, if it gets stuck in 1st or reverse, shift the gear lever on the column into the neutral position, open the hood and look at the linkages, they should be level with each other. If it's stuck in 1st you should be able to pull up on the lower linkage so they are both at the same height.
There is a mechanism inside the side cover of the gearbox that prevents you from selecting two gears at the same time. If this gets worn you will be able to to select 1st and 2nd at the same time. Instant breakage inside the box!

It's not the cover at this stage, if it was, your gearbox would be toast. I was just giving you a way to unjam the linkages from under the hood. It's wear in your linkages at this point.
 
I had shifting problems with my '46 Coupe, and the posts above are on the right track, with suggesting worn shift linkage bushings. When I replaced mine, I also found that one of the shift arms was loose on the shaft, as the securing pin #357534-S was worn, and the shaft #7231 was loose in the other arm. I took my shift cover off to do the repairs, but it is very tight to get out and back in again. If nothing is loose as I described, don't remove the cover. When the bushings are replaced, with the transmission shift arms in the neutral positions, put the shift rods on the transmission shift arms and connect to the gear shifter arms, with the shifter in the neutral position. Then check to see if the shift arms on the column at the front of the firewall are parallel to each other. If they are not, then you will need to adjust one of the the rod lengths.
