51 3speed column
Thanks ! Did the case have it's own # ? I have tracked down a #1C-7005A and do you know what "T191" refers to ? Thanks a bunch, I am putting this in my 52 F1 that I am restoring that came with a 4 on the floor. John

Hi John,
One more thing to look at before you are under your truck with the tranny sitting on your belly is your connection to the engine. I'm not sure if you have a 239 flathead V8 or a 215 OHV I6 in your truck. But that four on the floor has a "flywheel cover" and a seperate "clutch cover" that bolt to the back of the engine, then bolt to each other then bolts to the front of the four speed. the flywheel cover and clutch cover together make up what we call the "bell housing" today.
Your "three on the tree" light duty has the clutch cover cast as part of the transmission case and is not bolted on. So, you are going to have an extra clutch cover that goes with the 4 speed. Just make sure the flywheel cover that you have on your engine fits ok with the new cast clutch cover - it should.
Also, with that in mind, putting it back together might be a little different that taking it apart clutch wise!
Have fun,
Julie

LOL, if only you could drop the tranny out the bottom...
These are the column shift trans and the hogshead Julie is refering to. The "1/2 bellhousing" on the front of the trans is integral to the trans, it doesn't unbolt.

Ok ya caught me in a moment of senility.... I was thinking about my trucks, not the standard set up where the transmssion comes up through the floor.
I was thinking about the transmission removal on my 55. It had a 3 speed overdrive and a modified transmission cross member. Quite a different arrangement, but didn't even think about it.
My 51 has a C6 in it and it too goes in from the bottom because if it's attached to the engine theres not enough clearance angle between the ground and the fire wall when attached to the engine, and no way its going through the floor. I got under the trucks with both of those and rolled them up un my stomach then tightened ratcheting tie down straps to lift and hold them. Too cheap to rent a transmission jack, and the guys who were "helping" me told me it had to be done like that !

51 column shift 3 speed
Thanks everyone for your response ! As you can see in the picture of the transmission "ALBUQ F1" attached ,the front of the transmission has a double grind out for the starter can. The top grind out is what I had to grind out of my 51 tranny as they didn't have the 215 till 52 . It's bell housing (the 52)starter can mounts a little higher than the cast flat head did. Thanks again John

Re this part number
"A8C - 7001-A .. 3 Speed L/D Transmission / 2.78-1 ratio / Fits: 1948/52 F1 / Case marked (in paint) 3CS."
I'm concerned that it says 48/52. As I understand it, the column shift was introduced in 51, so the wouldn't the column shift tranny have a separate part number for just 51/52, different from the top shift 3 spd of earlier years?
And a question about the 52 4-spd. I've heard that they had a syncro 4-spd in 52 (crashbox earlier).
1) Does anyone know if that's true?
2) John, are you sure yours isn't a synchro 4-spd?
Thanks,
Jonas

A few points I have discovered over the years about these swaps are, 1- not all 4 speeds have a clutch bell that can be removed from the tranny case. 2- there are several different lenths of input shafts. 3- there are several different flywheel bells ( determined by the input shaft and clutch setup you have ) 4- flywheel bells for 6's and v8's are not interchangable.

A8C-7001-A / 1948/52 ~ Use with column shift.
21C-7001-A / (1942/47) 1948/50 ~ Use with floor shift.
This threads title pertains to a 1951 Column Shift 3 Speed.
That's why I didn't bother typing the floor shifter transmission part number, because it wasn't revelent.

I don't think Ford offered an all-synchro 4-sp until the '60's. Certainly not in '52. Even in the late '50's 1st was a granny with no synchro.

Here's the scoop on the 49-51 F1 transmissions. "Two different 3-speed transmission assemblies were used on F-Series Trucks. The 1949 and early 1950 F-1 trucks were equiped with the standard 3 speed center shift (floor shifter) transmission. The late 1950 and 1951 F-1 trucks were equipped with the standard 3-speed remote shift transmission (column shift).
A heavy duty 3-speed center shift transmission was also optional on the F1. The casing on the Heavy Duty is deeper (almost a cube) as opposed to the standard 3 speed which was more "shoe box" shaped. A heavy duty 3-speed remote transmission was made but used only in the F3 and F5 Parcel Deliverys.
The clutch housing containing the clutch release mechanism is bolted to the front side of the transmission case on the 3-speed heavy duty transmission. The 3-speed standard transmission has the clutch housing cast as in integral part of the transmission case.
Also as an option on the F1 was a 4-speed center shift sliding spur gear type transmission."
