1946 Ford Transmission
I just picked up this 3 spd from a 46' Sedan and I was wondering if there is a popular floor shift coversion that has been used? Also, how do you set it to neutral on the bench? I think the shift arms are froze in the cover even though they are shiny and oiled up. Am I missing something?

Re: 1946 Ford Transmission
For one thing the transmission is locked in 2 gears now. It is in 2nd gear and reverse. If the shifter is set this way you will have to remove the shift lever and move the forks to line up your shifter. Someone else may be able to explain better. Marv

Re: 1946 Ford Transmission
Sorry i forgot the answer. You will need to move the rear gear which is in reverse ahead about a inch. The front is in second gear and needs moved ahead 1 click which will center it and you will be able to hold the rear shaft and turn the front one. Marv

Re: 1946 Ford Transmission
Thanks for the info so far, but when I take the side cover off the arms on the outside still don't move.

If you have both levers centered in their neutral positions, and neither one will rotate, either the shafts are frozen/rusted or something has somehow jammed in the detent interlock part inside the cover. I guess this could occur if one or both of the detent balls (3/8" dia) have popped out.

Re: 1946 Ford Transmission
Are the detent balls rougly the size of a ball bearing? When I opened the cover there was a tiny spring laying in there, someone could have messed with it.

Re: 1946 Ford Transmission
The original Hurst 3-speed shifter mechanism was designed after more than one young hot rodder designed there own floor shift mechanism to operate the side shift transmissions. I remember seeing these in an old early 50s Hot Rod magazine. It seems like there was an article in one of the Popular Mechanics magazines too. The three speed types evolved into the 4-speed shifter after they went into production.

Re: 1946 Ford Transmission
So, I figured it out, got her into neutral and got the arms to move. They were a little seized up but a little persuasion loosened them up. I have a early Hurst shifter I am going to try out for the floor shift.

Re: 1946 Ford Transmission
spring about 3/4" long and small ball are the pieces for a blocker syncronizer-3 of each of them-by the picture I beleive yours are missing. See the holes in the hub that holds the second/third shift collar. Should also be 3-short "blockers" that go there also

Re: 1946 Ford Transmission
the blockers hold the syncro rings for both second and high, springs and balls present a type of lock to hold the blockers and to provide a grip on the shift coller. The blockers hold the syncro rings to bring the gears into sort of a speed alignment as you operate the shifter- the rings on the syncro's ( on inside) trap doping and this doping acts as a liquid clutch to allow the shift coller to come to speed with the gear being engaged-hope this is not too confusing and I am sure someone will provide further information

Re: 1946 Ford Transmission
I located a Hurst floorshift for the early Ford transmission WITH the proper brackets and linkage. They're not plentiful but they're out there. FYI - Hurst has a service whereby they'll rebuild the shifter to "as new" specs. Check their website. Good luck.

Re: 1946 Ford Transmission
You may not know about transmissions now, but you will when you have finished yours. The learning process is half the fun.

Re: 1946 Ford Transmission
Two things worth mentioning. The 37-39 case and 40-52 pickup case already is a top shifter. Also, if you really have a 46 V8 transmission you have the lowest gears put into an early Ford car or light pickup transmission.

Re: 1946 Ford Transmission
Agree with 38 coupe, you have a nice gear set there, find a top loader case from a early v-8 and transplant the gears into the top loader case. I have used cases all the way down to 35's and they will handle it. My current trans in my model a is a 48 gear set in a 38 case, I love it.

Re: 1946 Ford Transmission
I think I would need a book or a video on how to transplant gear sets! I know nothing about transmissions.

Re: 1946 Ford Transmission
You are not fully initated into the old Ford fraternity until you can remove, rebuild and install a transmission in the dark on a gravel road by yourself!! GRIN GRIN
I have gotten out of school, changed syncronizers, and made it to work on time. White shirt and tie. works good lasts long time |
