Some big dummy filled the trans with grease, any advice on getting it out so I can put lubricant back in? Thanks
 
You may want to pull the cover with shift rod off. Put it in neutral so the shifting forks are centered and lift the cover/shift rod assembly straight up.
Don't move the shifting forks out of position, or mark where they were when you pull the cover off. You will probably need a new gasket that can be made out of gasket paper.
There are drain holes in the casting that get gear oil to the bearings. The lubrication of the gears is essentially a splash system. Grease doesn't splash.

You don't want to overfill the case as it can leak out through the seals into the axles, making a mess of the brakes, eventually leaking out the final drives.
Fill plug on the top, Drain plug near the bottom. 3 1/2 pints is all that is necessary.

Is it regular axle grease or corn head grease? Corn head grease is much thinner but is commonly used when gear oil leaks out. It's still not right for the application but it will clean out easier than axle grease.
 
Hi,
The transmission oil drain plug is at the bottom of the trans, visible from under the platform.
The plug low on the left side of the trans is the oil level plug, fill it only to there.
 
Sorry to pirate your post, but while we are om the topic
Any one got a tip for getting the drain plug to turn loose?
I'm to the point of heating and beating but I'd rather not if someone has a handy tip

Hi,
You could buy a socket for square headed bolts, the size for the plug, for a 1/2" drive breaker bar. Don't let a wrench slip on the plug, it can round the head.

Glen,
Thanks for pointing that out, my mistake on the Fill Plug being the drain.
As Glen notes, here is the drain plug:

Try several applications of your favorite penetrant, let it soak for several days, then use an impact wrench set on the lowest setting.

Kerosene will work but you'd be best to fill it up and let it soak for a day or so to absorb into the grease and thin it out before the first draining. I'm not sure how well it will want to drain based on the small size of the transmission drain plug. Expect to do a few flush cycles.

Quality ratchets are pretty sturdy, but they have their limits. I would not recommend using a cheater pipe on a ratchet. I breaker bar is usually a little sturdier. (It is also a little cheaper when you break it with a cheater pipe.)
 
Yes, a breaker bar would be better. I thought the plug would turn before you broke anything, but a breaker bar would be better.
