Shop-air fluid pump that fills sealed transmissions through the check plug and pulls old ATF back out, with 26 adapters for BMW, Mercedes, VW and Ford.
If you are servicing a ZF 6HP or 8HP in a BMW, a Mercedes 722.9, a VW or Audi automatic, or a late Ford with no dipstick, the new fluid has to be pushed uphill into a fill or check plug on the side of the case. This 8 liter pump does that on shop air, and the same tank reverses to pull the old fluid out, so a drain-and-fill on a sealed unit becomes a one-person job on the lift.
You charge the clear 8 liter tank with ATF, connect your compressor, and set tank pressure on the regulator while watching the 0-80 psi (0-6 bar) gauge. An inline valve on the delivery hose meters flow into the fill port, so you can feed fluid in steadily and shut it off the moment it starts to weep back out of the check plug. Flip the two-way valve and the tank works in reverse, drawing used fluid out of the pan or down a dipstick tube into the tank. The graduated tank is the part a gravity bag cannot match: you read exactly how many liters went in, which is what you need when the service procedure gives a measured quantity followed by a hot level check.
Look up how your transmission is filled before you buy. If it has a threaded fill or check plug and no dipstick, a pressure pump is the practical way to get fluid in. Check the fluid type and the level check temperature for your unit first; our ZF 8HP fluid type and capacity and 722.9 fluid type and capacity guides cover two of the most common sealed units this kit is bought for. For the full sequence of draining, filling and setting the level, follow how to do a transmission drain and fill.
This is a universal service tool, not a vehicle-specific part. The adapter set is made for the fill plug sizes used by the brands listed above, but threads and plug angles can differ between transmission generations and model years. Hold your fill plug up to the adapters, or check its thread size, before the car is on the lift. If you work on Mercedes 7-speeds daily, a dedicated 722.9 fill adapter kit adds more variations, and the 33-piece sealed transmission adapter kit widens coverage further.

A shop air compressor. Air pressure in the tank pushes fluid out through the delivery hose, and the regulator and 0-80 psi gauge let you set that pressure. No electrical power is needed.
For most car and light truck fluid changes, yes. GM lists 7.7 liters for a 10L80 fluid change and 7.0 liters for an 8L80. Heavy-duty units such as the 10L1000 at 13.6 liters will need the tank refilled partway through.
Yes. Turning the two-way valve reverses the pump so it draws used fluid out of the pan or through a dipstick tube into the tank. Empty and clean the tank before charging it with new fluid.
The 26 adapters cover common fill plug threads used by BMW, Mercedes-Benz, Ford, Volkswagen, Porsche, Skoda and Volvo. Because threads and angles change between generations, compare your fill plug to the set before starting.
On most sealed units the level is correct when fluid begins to run back out of the check plug at the specified temperature. Use the tank markings to track how much went in and compare it to the service quantity.
