Air Operated Transmission Fluid Pump 8L, 15 ATF Adapters

Sealed transmissions with no dipstick have to be filled from underneath, through the fill or level plug, against gravity. This is the pump that does that job. It runs off shop compressed air, holds 8 liters (2.1 gallons), and switches between vacuum and pressure by pulling or seating a plug on the lid - pull vacuum to draw the old ATF out through the check plug or dipstick tube, then flip it to pressure and push measured new fluid back up into the case.

The reservoir is semi-transparent, so you can read the level against the graduations and put back exactly what came out, which is the whole game on a fill-plug-and-temperature-window procedure. A safety valve and vacuum gauge sit on the lid so you can see what the tank is holding and bleed it off before you crack the cover. The cover comes off with the included wrench for cleaning, which matters because a burnt drain-and-fill leaves varnish in the tank.

Fifteen all-metal ATF filler adapters come in the case, covering common European and Asian fill-plug threads including BMW, Porsche, Volkswagen, Audi and Honda applications. Hoses in the kit: one 60 in. main hose with a control valve and quick-connector, one 39 in. clear silicone hose (6 mm), and two 39 in. semi-rigid nylon tubes (8 mm and 10 mm) for feeding down a dipstick tube or up through a fill hole. Manufacturer part number B1G99039.
