This has been my go to:
OTC (2359) Oil Suction Gun https://www.amazon.com/dp/B00FJT0304/?tag=atomicindus08-20
I use that to remove fluid from power steering reservoirs.
I change my power steering fluids every two years.

In 20+ years wrenching on a dirt track Sprint Car, this seems to be the most efficient method. Get one with a screw-on cap on the outlet end, as it's quicker to pour in oil from a drain pan or a bottle than to attempt to **** it up. About a foot or so of hose is about right. In our case, it gives you enough flexibility to fill the rear without removing the RR tire when time is short.

If I was a real pro, I would use a mityvac for power steering reservoirs...

I know it sounds crazy, but it works like a charm with minimal effort. Use an enema kit. Only drawback is it takes overnight because of the viscosity of gear oil.

That's how I've done it for many years. Always works great.
Right? I can't imagine making sure your bearings and races are meticulously clean, carefully setting pinion bearing preload and backlash, reading the pattern, resetting pinion depth and backlash again, checking the pattern again, and repeating the process a million more times until you're happy and then tossing a plastic bag inside to contaminate the whole thing. I never knew a "racer" who did that. It must have been a joke.

A diff contaminated with an entire zip-lock bag of plastic is probably not going to last one lap of a race, lol

12 qts for the trans?
Buy a 5 gal bucket of oil and use a Lincoln pump.

Back in the day, the shop I worked in had something that looked just like that.

This thread is ridiculous. All of these posts over not wanting to spend ~ $10 on an Amsoil gear oil pump (or equivalent) likely available off of Amazon??? Most of us don’t have the need to MacGyver this solution as one may need to do in a third world country or in a remote location.
What has happened to professionalism and “the right tool for the job”????
There is one post here that is even totally misleading (and not even funny).
Be professional. It’s ~$10. If the profession gets a bad rap, maybe it is because of the extraordinary effort taken on stupid short cuts like this.
Tell your customer to buy the differential oil hand pump or add it to the bill after explaining the need and charge it as a shop supply.

But what if you already had a piece of vinyl hose and a gear oil container? Why order and wait for it to come from Amazon when you could be doing burnouts today?

Filling a differential is different than filling differentials. A 10$ pump is worth it,,, but you have had the recent experience of doing this, my bet its not something for a homebody to do every day, once a week, even once a year.

Just get a damn suction gun! Its how I change the oil in my Harleys.

Agree.
Only problem is mixing various weights of gear oils and GL-Ratings- which I never do and I think this is a bad idea.
The hand pumps are far cheaper than a drum of one type of fluid.
And takes up far less space.

12 Qts equaled 3 gallons when I was in school.
What oil goes in the trans?
What oil goes in the rear?
In the fleet I worked for 75w140 synthetic went in both trans and diffs, front hubs, forklift diffs and even the older trailer hubs do we know the op needs different oil in the diff and trans? No.

Yeah, using a suction gun on your back sounds fun.

He did not specify.
For my personal vehicles (modern SUVs) mine all require different differential oil than what is used in the automatic transmissions and transfer cases and, in one case, a manual 5-speed transmission.

12 qts is more like a Fuller 10 spd, could be an auto but it would have to be a dry rebuild to get 12 qts in it, off hand I cant think of a auto without a dipstick tube that is a simple refill they all need a scan tool to check the level at a given temp.

My H1 takes ~8+ quarts for the transmission, 4L80E. Synthetic ATF.
Scan tool is not used to check level. You use a dipstick.

Not on a Toyota Tacoma that doesn't have a dipstick... Wrench97 is correct. A scan tool is used to check fluid temperature - or you go back and forth some number of times with the shift lever to get the temperature warning light to tell you if you're in the right range for checking trans fluid level. Fluid level is then checked by removing the overflow bolt from the bottom of the pan. Crazy, stupid system, but that's what Toyota did...

Same here. 75w140 in the rear of my Mustang.
My biggest concern is the friction modifier. Last time I managed to spill a bunch on myself. OMG. That smell.

Yea you need a pump to pour it in the dipstick tube is the point.

Pump is not needed. A funnel works and it is cheap and easy. Just pour slowly.
A lot of shops use a B&G Products transfusion machine for ATF fluid exchange.
Except, many of the shops and dealerships never ever clean it after a flush and fill. Who wants to inject debris and dirt back into their transmission?????

The pumps that CGarage and others have recommended ****. 400 pumps to empty a quart. Flat backing it and have diffs, transfer case, and transmission to do? ***** for you! Gonna be pumping forever. Hopefully you packed a lunch.
Suction gun ***** too if you're working off your back. Makes a mess.
The garden sprayer is mess free, requires no effort, and is super easy to control how much fluid and when to stop. You can fill it and pressurize it before you slide under the vehicle. Nothing will drip out, no mess, if it tips over, zero spillage. Put the end into the hole and squeeze the lever. Lock it on for long fills. Release the lever when done and it instantly stops flowing. No mess. Garden sprayers are cheap, too. The plastic wand can be heated up and bent for your application. Bend a hook in the end and hang it on whatever you're filling.
At the end of the day, every vehicle is different and what works for one vehicle might not work as well for the next. Also, huge difference between laying under the car and standing under one on a lift. Flat backing it presents it's own challenges .

Not sure what planet you are on. Not true. Multiple pumps, yes. Not near 400. Sorry. It’s a 5-10 minute procedure *tops* for differentials with ~2.5 quart capacity...this is taking your time and being careful.
there's gravity all thru space
- the Big Boson told me that
Transfer pump works for me - already got it so I'll keep my sprayer for brake flushes, and... uh spraying things

It is everywhere in different strengths.
I have one fluid for the transfer case, one for the front and rear differentials and one more for the trans.
The red and black HF pump worked for the transfer case, the gear oil bottle for the front diff and some clear hose and the bottle will work for the rear diff and axles. All flatbacked. Small funnel for the trans.

Before you get fancy, droop the rear suspension as much as possible. Sometimes frame on stands, and unbolting shocks let's you turn a bottle with pointed ****** cap upside down into the vent or fill plug, easier than doing the pump and spill dance. I can yank my car's vent, tip two bottles in, and be done long before the day is old. Other vehicles may vary.
