Air-powered 10 liter tank that pulls old ATF out and pushes new fluid up through the fill plug on sealed transmissions, with 15 fill adapters.
Mercedes-Benz 722.6 and 722.9 automatics, like a lot of European and Asian transmissions, have no dipstick you can pull at the gas station. The filler pipe is capped and pinned, the level is read with a special tool, and the fluid has to go in a little at a time while the engine runs. This 10 liter pneumatic tank both pulls old fluid out and pushes new fluid in on shop air, with 15 fill adapters (ATF101 through ATF115) for side fill plugs and filler pipes.
A selector on the lid sets the job. In extract mode the tank pulls a vacuum, so you can draw used fluid out of a pan or down a filler pipe before you open anything. In dispense mode, air pressure pushes fresh ATF up the hose and into the case through the adapter you choose. A pressure gauge and safety valve on the lid let you keep tank pressure low and steady. Four hoses and a quick-connect air fitting are included. The 10 L (about 2.6 gal) tank covers a pan-drop refill on most cars and light trucks without stopping to reload. There is no hand pump, so you need a compressor.
Daimler's level-check procedure for the 722.6 has you put about 5 liters in before starting the engine after a full drain, start it and idle in Park, add the rest, then shift through the ranges and read the level with the dipstick tool. It warns that both too little and too much oil can cause malfunctions and damage, and that a precise check is only possible above 80 C (176 F). Topping up in small, controlled shots while the engine idles is exactly what a pressurized tank does well.
The other reason is fluid control. Mercedes star bulletin S-B-00.40/89d says the 236.14, 236.15 and 236.16 transmission oils must never be mixed and that separate filling units must be used for each. If you service more than one generation, empty and rinse the tank and hoses between fluids, or keep a tank dedicated to one fluid.
Identify the exact transmission and the fluid it calls for, because the right ATF matters as much as the right level. Our 722.6 fluid type and capacity guide lists the fill quantities by sub-variant, the 722.9 fluid guide covers the 7-speed, and the 722.6 filter and pan service walks through the drain step. Check that your fill plug or filler pipe matches one of the 15 adapters before you pressurize.
This is a universal tool, not a vehicle-specific part. The adapter set covers straight and angled fill probes, threaded plug adapters for common European and Asian sealed units, and a bent steel probe for tight holes. It works anywhere the fill hole sits at or above the fluid level: automatics, differentials, transfer cases, manual gearboxes and power steering. If you are not sure an adapter matches your plug, send us the year and VIN. Mercedes parts and fluids are in our 722 series collection.

Yes. Both extract and dispense modes run on shop air through the quick-connect fitting. There is no hand pump on this unit.
Yes. Those units fill through a capped filler pipe and need small top-ups while the engine idles, which this tank handles well. Use only the fluid Mercedes specifies for your transmission.
Empty and rinse the tank and hoses between fluids. Mercedes says its 236.14, 236.15 and 236.16 oils must never be mixed and calls for separate filling units for each.
10 liters, about 2.6 gallons. That covers a pan-drop refill on most cars and light trucks in one fill.
15 adapters numbered ATF101 through ATF115: straight and angled fill probes, threaded plug adapters for common European and Asian sealed units, and a bent steel probe. Match one to your plug before you pressurize.
Yes, anywhere the fill hole sits at or above the fluid level, including differentials, transfer cases, manual gearboxes and power steering.
