| | | | Joined: Oct 2016 Posts: 37 'Bolter | | 'Bolter Joined: Oct 2016 Posts: 37 | I have a 1955 Chevrolet 3100 first series with a 4 speed transmission. The transmission arm (lever) is sloppy. Is there a fix for this? I have a 4 speed transmission from a 1954 GMC, but it was from a closed drive shaft and mine is open. The shift arm on this transmission seems to be tighter than mine. Can I just switch the mechanism from one to the other without removing the transmission. Are there any simple alterations that could be made to the 1954 closed transmission that would work with my open drive shaft? Do all the 4 speed transmissions from previous years (before 1955) have synchromesh in first, second, and third? Not the granny. Your input would be greatly appreciated. Thank you. | | | | | Joined: Jan 2013 Posts: 1,518 'Bolter | | 'Bolter Joined: Jan 2013 Posts: 1,518 | Yes that shifter arm will work. The end of the arm gets worn and it gets sloppy, but keep in mind it is not tight like late model transmissions from the factory. You can remove the top loader after removing the center portion of your floor, it will be a direct swap ,no issues. Just make sure it is neutral before you pull the cover, The only diference between the early torque tube sm420s and the post 55 ones is the rear bearing housing and yoke/ujoint.
Granny is non syncho, but all post 48 trans have the synchro 2,3,4
