1949 Transmission

I don"t know of any but its not real hard take the 4bolts out of the rear ujoint on the rear end and pull the driveshaft out of the back of the trans make sure u drain oil first . Then disconnect the shifting arms, speedometer cable and the clutch arm from the side of the transmission.Take the 2 bolts out that hold transmission to the cross member once that is done support the rear of transmission with a jack. Take the three bolts out of the cross member from the bottom side of the car on each side now the fun starts getting the two bolts that hold the cross member on from the inside of the car located on the floor pan in the inside of the car in front of the seat should have rubber plugs over them. When u have the cross member lose get back under car and wiggle cross member out . then What I did was to lossen the 4 bolts tha thold trans to the bell housing ane silide the trans out Be careful that sucker is heavy. hope this helps
 
What Wayne said. I did this so many times on my 50 I could almost do it with my eyes closed. The hardest part is removing the cross member. Four bolts on each side. Don't forget to install a new pilot bearing ( I prefer the sealed roller bearing over the bushing style) and also a new throw out clutch bearing. Note: A transmission jack makes this a whole lot easier. If you think your clutch might be a little weak, now is the time to change it. Don't forget to support the engine with a bottle jack and a block of wood.
 
There is a hole at the back of the three speed transmission on the left side that is not threaded. I am leaking fluid from that hole. Also when i go thru the gears I see a rod moving back and forth in that hole. Is this normal and should that hole have a plug in it?
 
I forgot to say since its an overdrive you have to disconnect the wires for the solenoid and governor make sure to make where the wire go it Very important to grt them back where they belong also check to see if u can remove the hump cover for the floorboard makes getting some of the bolts out easier . remove the overdrive Cabel also
 
Found out there should be a plug in that hole from the factory. I guess I’ll have to fabricate something to seal it.
 
Just a bit of related information. While removing the transmission is not difficult, any clutch work complicates the process. This is because the bell housing is one piece, which will not allow access to the clutch unless it is removed. This requires the transmission to be removed first, and then lowering the rear of the engine to allow access to the top bolts on the bell housing.

The last time I did it, i was tempted to take a spare bell housing, cut it up, and weld some flanges on it so the bottom would be removeable (like a brand "C"). It sure would make life easier.
 
Being too old to handle a transmission, I made this out of scraps and it worked perfectly. The large hole is for the hole drain plug in the bottom of the trans.
Used 1/4" bolts at the rear mount. One draw back is the car has to be low enough that the jack can reach the trans.

The early 50s 4-bolt 259 type transmissions had a lock out switch held in place with two small bolts/screws. If someone removed the switch it will leave at least one open hole if the screws were put back in. These switches were deleted in early 1951 so later transmissions don't have them. A person could fabricate a small cover plate and use the screws to retain it. If it's a tapered plug boss it will have pipe thread in the bore.
 
Another jack option, it is not as tippy when the wheels are off the jack; the jack is screwed to the plywood.

I found out that the hole had a plug installed at the factory. I dont have to remove the trans anymore because I found the leak was coming from that hole. thank you everyone who tried to help. I need now to plug this hole.
 
There are cup type plugs that may work in your situation. You just bang them in the hole.

The hole is right below the speedometer cable entering the trans. That is leaking fluid quite a bit. This may sound funny but for a quick fix I installed a tapered 3/8 wood plug and it stopped the leak. I’ll try and get a picture.
 
Trying to put up picture. I think I got it.

Sounds to me like you just converted your car to a woodie! 😆
