Re: 1939 gearbox question
Shadetree: The transmission case and internals will fit the 35 without problems. Have to change the clutch release lever on the side of the transmission to the 35 lever, and use the 35 rear bearing retainer (motor mount). The 35 transmission cover (floor pan) will have to be modified slightly to accept the later transmission top, which has to be used due to the 3" shift fork, the shifter has to be changed to the 36 or later because the rod going into the top of the transmission for 35 is different and will not work with the double detent top.

Re: 1939 gearbox question
Other than the shifter handle, isn't the 40 and 41 half ton 3 speed truck trans the same as a 39 passenger car? At least insofar as ratios and interchangebility?

Re: 1939 gearbox question
The green parts book shows the #78 prefix transmission case,which was first used on the 1937 Ford-1939 Ford passenger cars as used on the 40-42 pickup and I think up to 1947,for the three speed.

Re: 1939 gearbox question
Thanks guys. I may never need it but good to have with all my other plunder. I took the top off when I first bought it and it looks great. To me it isn't worth the effort to change the original transmission out just to get a synchronized second gear and to keep it in second going down hill...

Run car around the block, drain out some of the oil to clear out whatever remaining water based stuff leaches out of cluster and bearings. |
