Helps if we have some information, what model of trans for instance, heck we don't even know if it is manual or automatic...
If he is removing a drain plug and adding gear oil, we will have to guess it's a manual trans. If it is a manual transmission, then it does not have a filter. The fun part is getting the oil back into the transmission. About mideway down the side you should see another plug. Pull that out, you fill the trans on level ground till the oil runs out of this midway plug. I have found the best way is to buy one those plastic pumps that screws into a gallon oil jug. Then pump the oil into the trans. If it's cold and the oil is cold, you will have a hard time getting it in there, the gear oil is thick.
I have tried several times to use one of those oil suckers that looks like a grease gun, to suck the oil out of the bottle and push it into the trans. I hate those things, I have never had one work very well and not create a mess. The pump thing I found works much better, just be easy with it, it is plastic.
Here's the type pump I bought. It screws right onto the jug threads. Autozone has it as part number W1139. I actually got mine on clearance, thought what do I have to lose? Pleasantly surprised it works so well, though I was using it to transfer hydraulic oil into my backhoe and got a little too aggressive with it and it fell apart. Had to mess with it a little bit to get it put back together. Part of the problem was I was using it to empty a 5 gallon bucket which it's not designed to fit, but it still worked with a longer pickup hose on it for the 5 gallon bucket.
When I did some work on my T18 I had the top shift tower off so after draining the oil (not a lot of it) I filled it thru the opening and could see the level and stopped when it got to the fill plug.

We have one of those drill operated transfer pumps at work. We got it off the cornwell truck one day and that thing works great for ATF and gear oil. Cornwell guy said it is capable of pumping 100w gear oil.
If there is no drain plug you will have to suck it out with the dreaded suction tool I hate. It looks like the picture below. If you are wondering about this and why in the world it doesn't have a drain plug remember, you are using this truck way beyond what Ford intended. They intended for this truck to last not more than 10 years, and then it wold be scrapped and you would go buy a new Ford truck. Balljoints don't have grease fittings, rearends and transmissions don't have drain plugs, and no spare parts for emissions devices. Sheetmetal is bare and unprotected on the backside. It's all in the plan.

Kinda like the 9" axle on my '82. I was going to drill the bottom of the axle housing out on mine and tap it with a pipe tap and make my own drain so I can drain my axle fluid. Will do this when I get my currie 9" third member to swap in.
