How do you fill your Muncie?
I am just about to put my car back down on the ground after my transmission work. I tried to fill the trans yesterday with gear lube but that stuff just doesn't flow like regular oil so I am wondering how you guys fill your trans while it is in the car? I am thinking about going and getting some sort of pump but I wanted to get your techniques.
Thanks
Thanks

I went to our local parts house and picked up a hand pump. It looks like bicycle pump for oil. Best part is that I can use it to suck the old fluid out when the time comes for that. After getting this it took less that 5 minutes.
Thanks everyone!!

Although filling it is not easy, removing old fluid is much more difficult. I tried sticking down a plastic tube attached to a vacuum pump and I couldn't get the plastic tube down into the interior portion of the transmission to get out the oil. The next time I take a transmission off to a rebuild shop, I'm going to ask them to put a drain plug in it even thought this is not a NCRS rework activity.
(PS I ultimately removed the old transmission fluid by removing the transmission, removing the fill plug, turning the transmission on its side and let all the old oil drain out.)

I used a long piece of hose, put one end in the fill hole and routed the other end up through the engine compartment. I was underneath the car and had a friend at the other end of the hose. We stuck a funnel on the end of the hose and poured the gear oil in until it filled up. This requires two people but it worked well for me. I could not get the gear oil bottle at the correct angle to squeeze into the fill hole.

And what year(s) did they NOT come with a drainplug?
My '72 has a drain plug, but I am not sure if this is the original/correct trans or not.

I think the drain plugs were added about 71 or 72, when they went to the fine spline maybe?
On the older ones I tap the bottom for 1/4 npt pipe plug and then use a bushing and 1/8 plug. You can drain it easier and the bushing prevents wearing out the tapped hole in the aluminum.

from an article somewhere: " For the 1970 model year, there were two major changes to the Muncie four-speed. In previous years only the M22 transmission had a drain plug, however, beginning in 1970 all Muncie four-speeds now had a drain plug."
Don't know what the 2nd major change was!

...been into boats for about as long as I've been into Corvettes. Have had this Mercury Marine boat lower unit pump since 1988. Screws into virtually all oil plastic quart bottles. I use it for tranny fluids, rear end fluids and stern drives. 
Best $9 I ever spent.
