Transmission flush help

Our lessons from an oil industry engineer......up to GL4 is good, although the GL1 has zero additives and generally only recommended for straight cut gearsets (no synchros). So what you can find these days is the plain GL1 and GL4......both ok on yellow metals. If you choose a GL5 oil, check with the refiner to confirm that it is ok with yellow metal. Some are and some aren't. This is why we only stock the GL4.
 
So a GL-4 would be good for a 1950 Ford Custom three speed, no O.D.? I have the original spec in my manual, but it's out in the shop. I was reading my manual today, frantically looking for the procedure to check and /or change the oil in the transmission. No luck! I crawled up this afternoon an identified the drain plug in the bottom of the transmission, but how do you fill or check the fluid level? I'm thinking that the plug on the side of the transmission case is for filling, and once the fluid starts run out of the fill hole then you are good to go. Is that right? Seems to be similar to my tractors of the same vintage.
Thanks in advance for any information.

Yep drain it from the bottom and fill it from the side, I have used one of those cheap suction guns I got a long time ago, you could also use a dollar store turkey blaster.
 
Mentioned the great help I have been getting here, to the wife. In particular the trick for filling the transmission. She said "you are what you use!", " get the turkey baster!":D
Anyways, thanks for the response.
Cheers
 
This is from the Workshop Manual for 49-51 F-Series, suggest the OP get one.

Thanks Ross, I have one for the 1950 Ford car. Neither actually helps when trying to find the equivalent oils in the 21st century! I really don't want to start trashing the car with improper oils, so it will sit until I find what I need. Here in Canada it is a lot more difficult to find the appropriate fluids, that's for sure!
 
When using GL5 oil that is supposedly rated GL4 as well, does the deterioration of 'yellow' metals happen when the car is idle?

Not really sure what you are referring to, Mac answered this in post #21 . GL-4 has been used by many, many v8ers for years with excellent results in transmissions. You are not going to get a much better source than Mac. I am baffled why you would want to use antiquated products? The other lubricants are equally readily availably (engine, rear axle, steering box, etc.).

I'm going with what Mac has stated, I respect his opinion that's for sure. I respect and appreciate the input and help for the rest of you guys as well. Problem is finding products here in Canada from my few local suppliers that fit the criteria. I'm an hour or more from town and my last trip in was unsuccessful! One place I was sure I could pick up the oil.... was closed early. I'll try again this week.
 
No idea about Canada, but in the U.S. GL4 is fairly common. I do a lot online and delivered to my door. 2 day free shipping, but that also may not be an option.
 
Most, if not everything we need up here needs to be ordered through suppliers in the U.S. At least that's what I seem to find. Even my 8N tractors parts that I order through a Canadian dealer most often has a Dennis Carpenter sticker on it! Makes this a very expensive hobby in this neck of the woods.
I'll be making another trip to town soon, so I'll scour the shops and see what I can find!
Cheers

In Canada I get Chevron 140 (ISO460) from local chevron dealer/ supply Inland Kenworth. It is a GL-1 mainly mineral oil but contains additives for anti foaming, rust protection and oxidization inhibitors. $130 for 20L pail. They also carry a 90(ISO150).
