Really have to pull the trans out through the car?

Unknown
edited November -1 in HUDSON
I was trying to stop gear lube sepage from the 3 spd trans and OD in a 49 Commodore. Read the manual and it says to remove the front seat and pull an access plate from the floor to remove the trans and bellhousing as a unit. Is this for real? So you have to pull the trans / OD / bellhousing from the motor and out through the interior of the car if you need to service the clutch, trans, or OD? If this is really true, how do you keep from ruining your interiors and also how do you heft the unit out of the car - engine hoist? Sorry if this question shows my inexperience with Hudsons. My 49 is my 1st Hudson.

  • Pulling the trans cover is so you can get to all the bell housing bolts, the trans still is removed from the bottom.

    And believe me, this unit is HEAVY! I used my portable crane, with an extension of 4" x 2" timber on the arm, and manouvered it into place over the transmission, so that I could slide it back and lower it gently to the floor. if you don't have access to one of these, then you need probably three people to do it easily, one each side up top, and one underneath. Tie a rope around the unit, with each end of the rop up top for the helpers to gently lower down. Also, when you take the top bolts out of the bell housing, fit a 2" long stud in each bolt hole, to enable the housing to slide back on. Makes it easier for re-insertion as well. Good luck,

    Geoff.

    With the front seat out of the way it is possible to get an OD gearbox out and back in through the hole in the floor. Bit of a struggle because of the length of the unit, and needs 2 people because of the weight, but it is do-able.

    Gary,



    This is true, but it's not as bad as you fear. When I've swapped transmissions this way, I was able to do most of the work from up above, didn't leave a mark on the interior, and didn't use any kind of hoist to do it.



    You remove the front carpet, and either remove or at least unbolt and scoot the front seat back. Cover them up with drop clothes, of course. Cover the sill plates with the same old bedspreads, etc. You do have to support the engine from below when you remove the transmission, so a floor jack is needed for this. I modified a simple angle iron to bolt to the crank flange, that rested across the front subframe rails.



    As long as you have two long pilot studs threaded into the top two engine to tranny bolt holes, it's a piece of cake. I was able to install an OD tranny from above by myself, while sitting down! I cradled the tranny in my arms, and simply slid it into place. Much easier than doing it from underneath, unless you have a vehicle hoist, which I unfortunately do not.



    Good Luck,

    Doug
  • The thing you have to do is remember that this is a job that was planned for a Hudson service facility. Two people can do the OD unit with minor trouble. The one you really don't want to take out through the interior is the hydramatic. That is a ZERO fun job. If you have a standard tranny it is very little trouble at all going through the floor access panel with an OD unit just take your time and it shouldn't be that big a deal Gary. Just as an aside, Hudson produced all stepdowns up until 1950 with a standard transmission floor access panel. With the advent of the 1951 model year all floor access panels were made to accomodate a hydramatic transmission whether the car was going to get one or not. The new floor panels were curved higher so as to allow for the larger hydramatic unit. Previous floor panels would not have worked as they were of a different contour for the lower setting three speeds. The higher setting hydramatic floorpans will accomodate both transmissions-but not the other way around. Moral here is to watch your floor acess panels when swapping trannys--it matters.

    Man, I learned an easier way to do it. I always hosted them out thru the car with bull beef and ignorance. Yas, the OD units were heavy. Fairly makes ya cipher.



    My record from GO to having it on the ground is 20 min. That's with all the bolts having been out recently. Having to dig the tar off'n em takes longer.



    I once changed a clutch disk in a ditch in a snowstorm without ever getting under the car. Try that with brand x.

    Have you been able to find where seepage is coming from? there are two plugs to put gear oil in as I'm sure you've seen. Rear seal doesn't require trans removal, driveshaft,yes. Front seal may be able to replace by sliding back enough to gain access. check the drain plugs for seepage. Don't be concerned about your questions,I know enough to be dangerous. As you've seen by the responses to your questions, Hudson folks are kind, gentle, respectful folks that want the same thing you do, a drivable Hudson and fellowship with others like you.

    I visit another forum and I can tell you they are a critical bunch, Ya have to watch what ya say, or they'll tell ya that ain't right,you have to do this way. The short time I've been on this forum and been allowed to participate, I've never read one critical word or statement, and that's the nature of Hudson people. I've driven my beater 49 Commodore to a number of meets and folks be just glad to have my car there as a prsitine restored Hudson. That makes for a great club supported by great people. One of the things I enjoy about Hudson meets and people is the fact, there's no judging. Everybody's come to enjoy themselves with others that have the same afflication.

    Thanks for letting me share,

  • In my 47 years as a mechanic mostly in dealerships if i learner nothing else i learned engeneers are not mechanics and the ones that wrote the shop manules never did it. I have always removed Hudson transmissions from the bottom but i had and still have trans jacks to do it with. The Motors flat rate manul gives 4.8 hours to R&R the trans with over drive. If you followed the Hudson shop manul it would take that long th get ready to change it.

    I am sure it can be done from the top but i have never tried it.

    Bill,

    I have been trying to figure it out myself. I have pulled only two 49's in my life. Both OD's one eight and one six(that one twice due to a Clifford disc that was too thick). Darned if I could figure out how to get either one out around the cross member. Maybe the bell housing can be unbolted from the transmission after taking it off the engine block? It wasn't that hard for a weakling like myself to wrestle them out through the floor and much cleaner than working on the ground on a gravel driveway! I must be missing something.The 54 Hydra-Matic? No problem.;)

    Dave W.
  • I think i am missing somthing here Bill & Dave. What is stoping me from moving it back after i jack up the rear of the engine? That has to be done no matter which way you go so the trans will go back far enough for the trans input shaft will clear the pressure plate.

    Hey, I'm no expert. I didn't say YOU can't do it.. I said "I" didn't know how to do it! I learn sumpthin' new every day. Don't forget, you are removing the bell housing along with the transmission. Give it a shot and let us know. I am only speaking from my personal experience. I didn't have to take an IQ test to own a Hudson! Thank goodness..LOL!

    Most of the things I have to fix on my Hudson are things I screwed up...

    Dave w.:D
  • You still have that rivited in cross member and all the hudsons I have ever worked on had the frame Xed just behind the trans with a hole for the drive shaft to go through. Now the auto trans cars had the cross member bolted in.
  • Well Bill you made me go look. I jacked up my 50 commadore and found the cross member you are talking about is 8 inches behind the over diive unit and is a half moon above the drive line not a hole inclosing the drive shaft. The top of the half moon is about 4 inches above the drive line leaving ampel room to move thr trans back far enough to remove it from the bottom.

    LJ
  • The cross member I know of is just under the front of trans and rear of bell houseing with the rear motor or trans mount, Where is the rear support on your commadore. Have never seen one like yours.
  • Bill what are we arguing about here. first you talk about the rear crossmenber behind the trans and then you talk about the crossmember under the bell housing that is cleared by raising the rear of the engine. If you are just trying to make me look bad then fine have at it

    I thought it was a disscussion! No argument here..

    Don't take this DISCUSSION personal. I know Bill well enough to know he wouldn't trying to make anyone look bad or hurt anyones feelings. That is certainly not MY intent. As with most people on the frum, we want to learn more about our favorite car. I make mistakes all the time and have been told about it here on the forum. I just take it in stride. I ain't perfect. I was berated for mentioning the use of Teflon tape on a fuel line. The berator didn't understand that I was talking about THREADED portion of a FLARE fitting to allow the fitting to be tightened enough to prevent leakage,.The threads don't come into contact with fuel as with a pipe fitting, (unless it's leaking). I didn't think it was important enough to further the discussion. I was right. He didn't fully understand what I said,,So what?..Exchanging ideas and OPINIONS is why this is called a FORUM.

    In this case, just a matter of us both trying to understand the situation. Obviously your Hudson is modified from the original factory configuration. It's not hard to imagine that these cars have had a few modifications over he past 50+ years. Later Stepdowns do have a removeable crossmember due to the size of the Hydramatic. I'm sure many have been cut, torched etc. By the way, the parking brake cable passes through and is anc****d to this crossmember as well. Where does you cable attach under the car? Perhaps a stub of the crossmember that has been cut out? I can't picture how the rear of the engine and transmission are supported without this crossmember under the tranny. A picture would be worth a thousand words.

    The original cross member Bill speaks of is situated in a position that the FACTORY says prohibits the transmission and bellhousing from being removed from below the car. That has been my and Bill's experience. So your contention that it can be removed piques our natural curiousity. You can understand our wondering what we are missing? Yes, the transmission can be slid back a ways if you use some long studs on the top. As others have mentioned, even some clutch work can be done. Go ahead and do it your way. I don't think Bill or I said you can't. We just want to know HOW. Report back.. Maybe a picture of your cars configuration?

    What ever you do...Make it fun and safe. Dave W

    LJ,

    Great pictures. Looks like you are expecting a cold winter (Firewood stack).. Do you have heat in the garage?

    Your pictures show the factory configuration. No modifications that I can see. Now, Measure the diameter of the bell housing and check the distance between the crossmember and the floor board. The bellhousing is larger than the space between them. The bellhousing cannot go backwards over the crossmember without the floorboard being removed. The engine can't be raised enough to drop the transmission forward.(By the way, the fan radiator clearance is close so be careful jacking the engine.) So the floorboard must come out and the transmission brought up and rearward. It will be inside the car at this point. Why not just drag it out and be done with it? My transmission looked like that until I pressure cleaned it, replaced the rear seal ,resealed the governor, and reverse lockout switch. Did that just a couple weeks ago along with a pinion seal.. No more driveway stains!

    If it ain't fun..don't do it! Dave w.
  • Dave I never said you did'nt have to pull the floorboard. My whole point was why do i want to manhandel it through tho car when all i have to do is turn the valve on the jack and let it down on the floor and roll it out from under the car. Yes i do have a wood stove in the shop. It does a prity good of keeping it warm. I intend to pull the engine and trans for a complete cleaning and seals as needed.

    LJ ,

    I owe you an apology. All along, I thought you were trying to avoid taking the inside of the car apart. Don't know where I got that idea, perhaps from someone elses post. but that was the thinking on this side. I stand corrected.



    You will still have to remove the rod that supports the brake mechanism.



    Having a transmission jack is a luxury I never had. I'm just now getting used to a roll around jack thanks to Harbor freight. "Back in the day" I only had a bottle jack and a lot of random size pieces of wood. I do have a two post lift in the shop now. The older I get, the less heavy work I do and the better tools I can afford. Life ain't fair!

    Now get out in the garage and "drop" the tranny.

    Dave W.
  • Thanks Dave. I owe Billy K A apology for the stupid remark i made on Wednesday. I am sorry bill it was a dumb thing to say.

    I heartily agree that taking the tranny out the bottom is a whole lot easier on the body (of the owner/mechanic!) You do have to take some of the brake support structure out of the way, but that effort is easily worth it. I just use a shop jack also ... it's a bit of a balancing act, but it works. Be sure to have the car up off the floor quite a way, or you'll not be able to get the tranny/bellhousing assembly out from under once you've got it down to the floor. And using the guide studs at the two topmost bolt positions is crucial, for removal without damage, and especially for getting the assembly back in place.

  • I have the transmission jack that Harbor Freight sells. It is a decent part, and I think it was like 35 bucks. You probably shouldn't stick an impact wrench in the jackscrew to raise and lower it, but that's what I do. It's been through about 10 uses so far (which would constitute R&Rs, so 10 removals and 10 installs, 20 uses total) and still works pretty good. Need to keep the jackscrew greased or it will bind up. It is sort of trouble to fool with, but it's better than a floor jack. I would like to get another "foot" for my floor jack and weld a large piece of steel to it to make a big flat jacking surface for doing trannys. I also believe there are jack adapters made to do this, but steel is cheaper and I have a welder.



    Good luck.

    Some years ago I welded up a sadle adapter for my floorjack that fit the rear axle assembly on our Monte Carlo stock car. We changed rears twice a week and that little adapter was a life saver. I could do the whole switch in a half hour by myself.. Just needed a little help bleeding the brakes.( I loaned my pressure bleeder to another racer and never got it back). I was going to make a similar adapter for the Turbo Hydramatic, but found the transmission to be pretty much reliable, so we never needed it.
