10L Pneumatic ATF Fill & Extract Pump, 22 Adapters

Servicing a sealed, dipstick-less automatic such as a GM 6L80, Ford 6R80, ZF 8HP or Mercedes 722.9 means pushing fluid up into a fill plug on the side or bottom of the case, often with the car on a lift and the engine running. This shop-air powered 10 liter pump does both halves of that job: it pulls spent ATF out, then pressurizes the tank and dispenses fresh fluid through one of 22 metal fill adapters, so one person can complete a drain-and-fill without a squeeze bottle or a hand pump.

What this pump does in a fluid service

The tank connects to your compressor through a swivel air inlet. A selector valve switches it between extract, where the air flow pulls a vacuum and draws fluid in through the extraction tube, and dispense, where the air pressurizes the tank and pushes fluid out through the 2 meter hose and control gun. A trigger lock holds flow on so you can watch the fill plug instead of squeezing a handle, and a relief valve preset at 43 psi (3 bar) vents excess pressure so the tank cannot be over-pressurized by shop air. Usable capacity is about 9.5 liters, which covers a pan-and-filter refill on most passenger car and light truck units in one tank.

Why a sealed transmission needs it

• No dipstick tube: fluid goes in through a threaded fill or check port, and the level is set when fluid runs back out of that port at the specified temperature.
• Temperature matters: most sealed units are checked hot with the engine running, so you need flow you can start and stop instantly while working under the car.
• Multiple changes: some fixes call for more than one drain-and-fill. GM, for example, has used three DEXRON VI drain-and-fills with a filter change on the last for a 6L80 and 6L90 shudder concern, which is a lot of fluid to move by hand.
• Thread protection: the metal adapters thread into the fill ports instead of forcing a plastic fitting into an aluminum case.

How to confirm it fits your work

Check whether your transmission fills through a side or bottom plug rather than a dipstick tube, and look up the fill-port thread for your unit; the included universal tube covers older units that still fill through a dipstick tube. If you are not sure whether a full exchange or a drain-and-fill is right for your mileage, read flush vs drain and fill first, then follow the step-by-step in how to do a transmission drain and fill.

Fitment and coverage

The adapters are OE-style metal fittings intended for common sealed automatics, including the GM 6L80 and 6L90, Ford 6R80, ZF 8HP and Mercedes 722.9, plus a universal tube for dipstick-fill units. Fill threads vary between manufacturers and sometimes between model years, so match the adapter to your fill plug before you start; if a unit you service is not covered, a larger 33-piece fill adapter kit or a dedicated GM 6L80, 8L90 and 10L80 filler adapter attaches the same way.

Using it on the car

• Keep fluids separate: run a little clean fluid of the new type through the hose and gun before dispensing, so a previous job's ATF does not mix into a different specification.
• The lid is torqued down at the factory and is easier to fill by drawing fluid in from bottles in extract mode than by unscrewing the cap.
• Use the fluid your transmission calls for, such as DEXRON VI for a 6L80 or ZF LifeguardFluid 8 for an 8HP, and set the final level hot through the check plug per the service procedure, as covered in the 6L80 service guide.
• Release tank pressure before changing adapters or opening the lid.

Does it need shop air?

Yes. The pump runs from a compressor through its swivel air inlet for both extraction and dispensing. A relief valve preset at 43 psi (3 bar) limits tank pressure.

How much fluid does it hold?

The tank is rated 10 liters with about 9.5 liters usable, enough for a pan and filter refill on most cars and light trucks in one tank.

Which transmissions do the adapters fit?

The 22 metal adapters are meant for common sealed automatics such as the GM 6L80/6L90, Ford 6R80, ZF 8HP and Mercedes 722.9, and a universal tube handles dipstick-fill units. Check your fill-port thread before starting, since threads vary.

Can I use it to pull fluid out through the dipstick tube?

Yes. In extract mode the tank draws fluid in through the extraction tube, which can go down a dipstick tube or into a drain pan, then the same tank dispenses fresh fluid.

Can I use it for different fluid types?

Yes, but purge the hose and gun with the new fluid before each job so ATF specifications do not mix, and keep the tank clean between services.
