Air-driven 2.1-gallon pump that pulls old ATF out and pushes new fluid up through tight sealed-transmission fill ports, with 15 metal adapters for GM, Ford, BMW, Honda.
Changing fluid in a Ford 6R80 F-150 or Expedition, a GM 6L80 Silverado or Tahoe, or any automatic without a pour-down tube means working through a plug in the side of the case while you lie under the truck. This 8 liter air-operated pump handles that job from your compressor. Flip the pin valve one way and it pulls old fluid out under vacuum; flip it the other way and it pushes new ATF up through a thin tube into the fill hole, with 15 all-metal adapters for the plug threads on GM, Ford, BMW, Porsche, VW, Audi and Honda units.
A fill hole on the side of a case is usually not much bigger than the hose you are feeding into it. With a funnel there is nowhere for air to escape, so fluid burps back out and you never know how much actually went in. The narrow tube from this pump leaves room around it for the transmission to vent, and the control valve on the 60 inch main hose lets you stop the flow the moment fluid starts to weep back out of the hole. The tank is semi-transparent, so you can see how much has left it.
The same tank works in reverse. In extract mode it pulls a vacuum and draws old ATF out through a dipstick tube, a fill hole or a cooler line, which is handy for a partial change between pan services or for measuring how much came out before you put fresh fluid back in.
On a Ford 6R80 there is no tube under the hood. Ford's procedure has you run the engine, hold the selector in each position for about 5 seconds, return to Park, then remove the fill plug on the case and read the level indicator attached to it; the correct level is at the top of the dotted area, using MERCON LV. Our 6R80 fluid type and capacity guide and the 6R80 F-150 fluid change walk-through cover the full sequence. For GM trucks, check the 6L80 fluid type and capacity guide for your model year, since GM changed how the level is checked during the 6L80 run.
This is a universal tool. The 8 liter tank holds about 2.1 gallons, which covers a typical pan service: GM lists roughly 5.7 liters (6.0 quarts) for a 6L80 pan and filter change, so one tank does the job with fluid to spare. The case holds 15 all-metal ATF filler adapters, a 60 inch main hose with a quick-connect control valve, a clear 6 mm silicone hose, 8 mm and 10 mm semi-rigid nylon tubes, and a brake-bleed hose. Thread the adapter into the plug hole by hand before you pressurize anything. If your GM 6L80, 8L90 or 10L80 needs a dedicated fitting, add the GM ATF filler adapter; for more thread sizes, the 33-piece sealed transmission adapter kit fills the gaps. More service tools are in our tools category.
The finished unit weighs about 8.5 pounds and packs into its own storage case, so it lives on the shelf next to the drain pan instead of in a pile of loose hoses.

Yes. The 6R80 is filled and checked at the plug on the side of the case. Feed MERCON LV through the thin tube, then set the level with the engine running and read the indicator on the fill plug, at the top of the dotted area.
8 liters, about 2.1 gallons. That is more than a typical pan and filter service on a GM 6L80, which GM lists at roughly 5.7 liters (6.0 quarts).
A tank compressor that holds around 110 to 120 psi. The pump uses a lot of air, especially when extracting, and a small pancake compressor will cycle constantly and slow it down.
Yes. The pin in the control valve switches between modes: pin in pressurizes the tank to dispense, pin out pulls a vacuum to extract through a dipstick tube, fill hole or line.
Rinse and drain the tank between fluid types. Mixing a little DEXRON into a MERCON LV fill, or the reverse, is exactly what you are trying to avoid on a modern automatic.
