Fluid extractor for transmission fluid

If it's a 4L60E w/standard pan, 4 quarts, even though the manual says 5 quarts with a pan drop. This is because the additional quart is only removed when you pull off the filter.
If you have a deep pan, possibly an additional 1-2 quarts.

Yep, you'll get close to what's in the pan. Usually ~4qts I've never hand pumped out my 4L60E thru the dipstick tube since it's so easy to pop a cooler line and let the trans do the pumping for you.

From the 4L60E in my son's 94 Camaro, I only get out about 2 quarts.
A poster somewhere ( here maybe ) told me there's an obstruction below the dipstick tube and the suction tube can't go all the way to the bottom of the pan. I haven't looked at it while I had the pan off.
I drain those two quarts at each oil change. A couple times I did it twice, circulating it for a few minutes in between.

Disconnect ATF cooler line. Aim into bucket. Start vehicle. Shut off when gallon of ATF is removed or if air bubbles show up. Top off fluid and repeat until happy. 2nd person to work the 'keys' is beneficial.
Some vehicles don't have easy to remove ATF lines and might require a special tool.
You'll have to figure out which line is the ATF PSI line. Trial and error!
The factory service manual's ATF flow diagram would be helpful.

With an extractor, you will probably get around three quarts, maybe a bit more if you have the nose of the car pitched down.
I can drain 4 qts out of the 4L60E in my S-10 Blazer (installed a drain plug on that one). On level ground, I can extract about three quarts out of the 4L60E in my GTO (haven't looked to see if it has a drain plug).
The 4L80E in my Xj12 yields about 4 qts, whether it is drained through the plug or extracted.

From my experience, when using extractors to pull tranny fluid, you will get a lot more fluid out if you let the car rest for a few hours and let the fluid drain out of the torque convertor.
Using this method, I can pull 7 qts from my Taurus. If I try to do it when the fluid is hot, I will only get around 3 quarts.
This is the best deal I've found on the MityVac

KC, different application, but on my trailblazer, the line to the cooler (pressurized line) is on the right side of the lower radiator tank. It's got the fancy e-clip fittings, but they are fairly easy to work with provided they are not corroded. I have a set of napa plastic 'fitting removal' tools, but I can never get them to work right. I just gently pop off the spring clip with a pick. Sometimes you get lucky locating the line to the cooler by feel. The hotter line is *usually* the one to the cooler (the one you want to pull).

Using a hand pump I can remove 3 quarts from the pan of my F150. Considering it holds around 14 quarts this is only about 20% of the fluid. I do this every 10-15K and the fluid looks great. Needless to say, if the tranny has never be serviced this method may not be the best unless you're willing to extract and fill 3 or 4 times. If the fluid looks good and filter has been changed in the last 30K or so extracting 3-4 quarts and filling regularly can keep the fluid fresh and since you're only buying a few quarts at time its cheap to do.
