How do you Fill your transmission

Ok this my sound like a dumb question but how do you fill your transmission? I have a 1959 tr3a and I removed my carpet over the transmission to see if there was a hole where I could get to a filler plug or something. To my dismay I found no holes just one over the knuckle of the drive shaft and there is one small hole on the drivers side that goes to a square headed plug which my guess is the over flow plug. So how and where do I fill this thing. Thanks for any help guys.
 
For the relatively few times I've had to do this, I just got a simple pump oiler (from Home Depot, but anyone's should be fine). If the gearbox is really low, you'll be refiling that pump oiler a few times, but it's still pretty cheap and effective!
 
So take a pump and remove the plug on the side and put 2 3/4 qts of oil in the trans like that? I have already drained the trans and I need to fill it back up
 
Use a syringe like filler, looks just like a big syringe with a hose on the end, suck up the oil and push it into the transmission, holds around 12 ounces so will need to fill it 2 or 3 times, only takes 5 minutes.
can be bought at all the normal places.
 
Most auto parts stores, or Home Depot or Lowes, have hand pumps that screw into the oil container. The hose connections can be a pain as some of the pumps do not fit very well and the hoses will get slick with oil (might just be my being clumsy). Bottom line is it can still be a bit messy, but works well.
 
Fill on the side until oil comes out the hole. Then put in the plug. If its an O.D. you'll have to drive it (or run on jack stands) and re-check oil leval.

I changed the square-headed plug with a hex-headed plug. Found it at a industrial hardware store (not one where most of the hardware is made in China, only some of the hardware is made in China). Now I can actually get a shallow socket on the plug. Ever noticed how a square-headed plug gets centered on just that one spot where you can't get a purchase on the head? I, too, use a large plastic irrigating syringe I got from the pharmacy onto which I jambed a long piece of 1/4" poly tubing. Suck it in, squirt it out. The syringe is reusuable. Holds a couple of ounces.

I can fill from the bottom with the tunnel in place. Ditto for checking oil level. Open up the plug, squirt in a little oil and stop when it overflows.

I had an oil suction gun once, many years ago...and I HATED it! Never seemed to actually hold whatever fluid long enough to get from container to gearbox (or '51 Chevy remote oil filter to waste oil jug). Depending on what sort of access you have to the filler, I suppose even a cheapo kitchen "turkey baster" might work.
 
well I finally got it done, it wasn't that bad. I wound up using something that looked like a turkey baster with a tube on it to fill it up. After that I took it for a drive and it ran like a dream. Thanks for the help guys
