Topic: Adding trans oil

  Do any of you shade tree mechanics have a home made set up for putting trans lube in a transmission? I only have to add a small amount every year and don't particularly want to buy the big pump set up. It is a messy unhandy job otherwise.

  You can purchase a high quality (I prefer Lincoln brand) suction pump / gun for about $14. Looks a lot like a grease gun. It doesn't get any more reasonable or easier...

  Don't know what year of car you have or what your transmission is like but if it's like mine in my '47 I add transmission oil straight out of the bottle by opening the bottle, putting my thumb over the end of the nozzle, lifting the bottle upside down into the space above the transmission filler hole, then quickly remove my thumb and stick the nozzle into the hole then squeeze. Can't cut too much off the nozzle for this to work but it does work - for my '47.

An alternative for adding a very small amount, which I use to add a little ZDDP to the transmission, is to use a battery water filler bulb. It will probably hold 1/2 cup of oil to put in that way. I even commandeered my wife's basting syringe before I got the bulb. Had to buy her a new syringe.

  A small plastic bottle that's squeezable will do.
(Look in you wife's hair color supplies)
It holds maybe 4 oz and has a long spout.
Fill it with gear lube, open the side plug on the transmission and fill it by squeezing until the lube runs out, then replace the plug. (Also works the rear end of Early V8's)
Works for me!
(P.S. Do not return it to your wife's hair supplies)

  Three simple ways to put gear oil into a trans or differential;
1. Gear oil is generally sold by the quart. Cut the tip off to allow for about a 3/8" hole.. Attach a clear piece of tubing to the tip, (large enough to fit over the tip) put the clear tubing into trans, etc., squeeze the bottle to expel the oil..
2. Secure a section of clear tubing to the tip on a small funnel.. Insert the tubing into the trans fill hole, carefully pore gear oil into funnel.
3. All of the above fail due to a lack of supplies.. Carefully flip the vehicle up onto it's side, pore the gear oil into the trans, flip the vehicle back onto it's wheels.
Note... Differentials pose a problem because the vehicle will have to be stood on it's nose, which can result in damage to the grille, especially on the fat fendered pre '42 cars..

  Bill is correct, but for two minor details;
#1 Gear lube is so sticky that the clear tube gets full snd only a portion goes in, the rest stays in the tube and the bottle.
Ever notice you can't get gear lube off anything?
#2 Some of us don't have tall enough ceilings to stand our cars on end in the garage.

  Is the fill hole on the driver's side about halfway up the side of the trans?

My fill plugs are on the passenger side of my 34's & 35.

  Recently changed both trans and diff. oil using kubes40' suggestion of a suction gun. Required 2 1/2 fillings for each. Worked great!

  When i need to add a small amount of gear lube to transmission or rear in my '35's I use a liquid soap type pump bottle like you can buy most anywhere for dispensing hand soap in a bathroom or kitchen. Works very well. I carry a bottle like this filled with gear oil in my touring supplies/spare parts box.

  Regardless of how you fill your transmission, try to keep the level a bit below the filler hole, and you will substantially reduce leakage. If you overfill, some of the oil will migrate down the torque tube into the rear end. Be sure to check the oil level in the rear end occasionally, and drain any excess above the filler hole to prevent oil from reaching the brakes. The axle oil seals seldom prevent it, as they are probably originals that can't be replaced without a full disassembly of the rear end.
