    I ended up with a flathead 3 sp tranny that has a tailshaft off what looks to be a '49-'53 Ford overdrive tranny. It was all coupled to a 354 Hemi that never was put on the road. What does someone recommend to unstick the guts ? The top is off but I don't see much rust at all. Thanks for any advice.

    "The top is off". Is this a later model "top-loader" or an early Ford type with a shifter on top? Does it have a regular 4 bolt pattern where it bolts to the adapter or is it the large pattern like an early Ford? It may be stuck in two gears; if you can move any of the gears manually, perhaps you can get them in the proper positions.

    It has the bellhousing as part of the case, top shifter which is off at this time. The seller said he tried to get any gear to turn but was unsuccessful. I would like to install it in my '40 sedan which has the stock leaking flathead 3-sp coupled to a nice 327. The banjo 4:11 will be swapped for an 8" or 9" Ford/Maverick V8 rearend. I've never seen this type tranny with an o/d tailshaft, open drive setup. It really looks like the entire tailshaft off a '49-'53 Ford flathead 3-sp with o/d. I was thinking about filling the case with molasses and soaking it for a while.

    I bought the early hemi adapter to early Ford tranny from the guy who gave me the stuck tranny. This particular guy has never owned a '37 coupe that I know of. He lives is China Grove, I think.

    A couple pictures of this transmission would be very helpful. Something doesn’t sound right.

    Yeah...Picture! After post#7, my reaction was "Ain't no such thing."
    I don't know of a top-shift box that will take what must be a '49 Merc type OD!
    Early Ford type OD boxes (Lincon V12, '49 Merc) had different casting at the back to accept the overdrive.

    I have not seen a top shifter with OD. There is a rod that is pushed by the first/reverse lever when in reverse to lock out the freewheeling. That is what locks the trans from having the car able to roll when parked. You always put an OD car in reverse when parked. I once had a wreck when parked.
    I can't see the rod working with a top shifter.

    Yeah i have to agree with Andy it sounds like the lockout lever is jammed in the trans. The trans isn’t that hard to take apart and put back together but i would see if the rod looking from back of trans forward left upper side is in or outward if in pull it back out. You may have to get a screw driver in side at an angle to help it be gentle i mean real gentle these break real easy. A pic would help though I’m just going on the fly here.

    Oh, HELL YES, Quincy. Plus, we have tacos smothered in guacamole(pronounced "wa ca mo le"). So many "foreigners" call it "gwa ca mo lee". Gotta get it right.
    O.M.G. Taking pictures of such doggies in Texas would almost qualify for animal abuse. LOL

    This is new info to me. I replaced the synchronizers in a '39 way back in '73. That trans went behind an "Iron Duke" in my '34 2-dr. It was very simple. I will look for this rod when I get home in a few days. I have never seen a flathead tranny with this tailshaft housing. There is no adapter that couples the case to the tailshaft housing. I'll get some shots of it so you guys can see it, then tell me what the hell I have. It would be a great solution to maintaining my stock x-member and still have a true cruiser. I don't want to pull the body and install a 700R4 because the car has been rewired with a professional kit and is all together and actually runs fine but is no good for my long-winded cruises. I wouldn't have to pull the body if this freaky looking unit could be used together with a dropout rear from Ford.

    It should look something like this I think.

    Gary, I did a roughly similar trans swap on a ‘47 Ford Coupe I had about ten years ago. I had a’53 Merc Flathead and stock driveline with 3.78 gears. It need a more highway friendly ratio. By chance I happened into a ‘49/‘50 Merc trans (non-OD) and noticed the bolt in capability of the front of the trans but had to investigate the back side compatibility with the X member. And, of course, an open drive rear axle. The latter was easy with a Chassis Engineering kit and an 8” Ford rear end.

    But back to the X member. It was necessary to remove the original trans mount support from the X member to provide clearance for the tailshaft housing. I drilled the rivets of the bottom plate at X, then drilled the rivets of the trans mount support, fabricated a new mount support compatible with the new trans...then bolted the bottom plate back on ......voila’.

    All that said, I had considered how all that would work with an O/D trans. I did not have to measure, but ‘eyeballing’ the X member, clearance would be questionable and most certainly really tight at a minimum...... it would not surprise me that a modification of the X member could be necessary. The solenoid and governor being the most likely areas of interference.

    Bearing mind, I was dealing with a ‘47 era chassis, not a ‘40, but the X member has to be very similar.

    I took several shots of the tranny. Now, I have never posted photos from my Android to this site, or to any site. Can you steer me through how to do this ?

    This blowup looks like my trans EXCEPT this one has no bellhousing as part of the case. Also, my tranny is a top shift, like a '39. I just added this last comment at 430 am, Tuesday.

    I just took some shots of the tranny and I didn't notice a rod on the left side of the case., not that it isn't there. Hopefully, one of you can explain how to post pics from my cellphone. I'm on my laptop but can go to a desktop if that will help.

    I hadn't even considered the room needed for the solenoid on one side and the kickdown ? on the other side.

    Putting the OD trans in a 35 to 40 frame is not easy but can be done with some significant modifications to the X member. I covered the install and frame modifications that I made in my 40 ford coupe build thread a few years ago . The main change I would make to the install is to make the bottom center plate removable. The only reason I didn't was because I wanted to leave the socket for the wishbone intact. The way it is configured now requires me to pull the engine out to remove the transmission. You can see the modifications made starting on Page 5 post 146 of the old thread titled, A forty ford coupe for Uncle Mike. http://www.jalopyjournal.com/forum/threads/a-40-ford-coupe-for-uncle-mike-build-thread.949053/

    Gary sent me some pictures of the transmission and I am posting them for him.
    I don't think I have ever seen one like this. It must be really rare. My best guess is 49-50 pick up. MacVP needs to chime in. Could it be a combination of Lincoln and Ford parts????
    The case looks like a 78 Ford case and the OD a BW.

    WOW! I wouldn't have believed it unless I saw it. I would agree early fifties Ford pickup. I don't know if they came with overdrive, though. It will be interesting to see what Mac has to say.

    EDIT : Just did some checking and it looks like OD was not available on Ford pickups until 1953. Also, I would imagine that if it was, you had to have the column shift. Perhaps a one-off combination of a floorshift transmission and a late forties Lincoln OD?

    It would be nice to know the tooth count on the input.
    It must have worked as you can see the remains of the speedo cable and the lock out cable.

    Were Lincolns torque tube drive through '48 models like the Ford/Mercury cars?? And when did OD become available on Lincolns? Did they use the Columbia 2 spd axle like the Fords/Mercs?

    Interesting. I bet this is a custom job that is often discussed and rarely completed - adapting an OD tail to a '39 style toploader...
     
  30. The second pic suggests why it is stuck.
    It is rusted to fuck.
