Threads into the fill plug on dipstick-less transmissions like the Mercedes 722.9, VW DSG and CVT units so you can pump ATF in without spilling it.
A Mercedes 7G-Tronic has no dipstick and no fill tube under the hood, so the first time most owners try a 722.9 fluid service they discover the fluid has to go in from underneath, through a threaded hole in the pan, against gravity. This 32-piece aluminum fill adapter kit is for that job. It is also the kit to grab if you service a mix of cars, because the same sealed-fill design shows up on VW and Audi DSG and 09G units, most CVTs and a long list of Ford, BMW, Nissan, Toyota, Honda, Volvo and Porsche automatics.
On the 722.9 the fill point is the plug in the bottom of the oil pan. Behind it sits an overflow pipe that sets the correct level: you pump fluid in until it starts to come back out of that pipe at the specified temperature. Without an adapter that threads into the hole and seals, you cannot hold pressure against the incoming stream, and most of what you pump ends up on the floor. In this kit the Mercedes 722.9 piece is adapter ATF109, an M12 x 1.5 thread, which matches the 12 mm x 1.5 fill thread called out in Mercedes workshop information for this transmission. Your pump hose clicks onto the included brass quick-connect coupler, and the coupler's shutoff valve lets you stop flow before you unthread the adapter.
Every adapter is laser-numbered and has its own numbered slot in the case. A reference chart in the lid ties the number to the application. A few examples from that chart: ATF101 is 1/8-27 NPT for Ford, ATF105 is M10 x 1.0 for the VW/Audi 09G, ATF106 is M24 x 1.25 for the 02E DSG, ATF107 is M22 x 1.5 for VW/Audi CVT and ATF108 is M18 x 1.5 for VW and Skoda. Long straight and angled probes reach fill holes tucked up behind a subframe.
The 722.9 came in two fluid generations that should not be mixed. Units from August 2003 used red ATF to sheet 236.14 with the level checked at 45 C, and units built after about June 2010 moved to blue 236.15, recognizable by a different pan pattern and a green overflow pipe. Mercedes has warned in a published bulletin against mixing 236.14, 236.15 and 236.16 oils. Our 722.9 fluid change guide explains the pan-drop versus full-exchange quantities, and if you are chasing a wet pan rather than doing scheduled service, read 722.9 fluid leak common spots first so you fix the leak before you refill. You will also need a way to read transmission temperature, such as the Mercedes full-system scan tool, because the level is only correct at the specified temperature.
This is a tool kit, not a vehicle-specific part, so fitment comes down to the thread in your fill or check plug. For the Mercedes 722.9 use ATF109 (M12 x 1.5). For other makes, look up the adapter on the included chart, or measure the plug you removed and match the thread. Always start the adapter by hand. If it does not run in smoothly for several turns, stop: aluminum pan threads are easy to strip and expensive to fix. The coupler fits common hand pumps and pneumatic ATF fill pumps. The pump itself is not part of this kit. Everything we stock for the 722.6 and 722.9 is on the 722 parts page.
If you only work on Mercedes and VW group cars and want a smaller case, compare it with our 26-piece fill adapter kit. The 32-piece kit is the better pick when you see a wider mix of makes and want numbered pieces you can find quickly.

ATF109, the M12 x 1.5 adapter. That thread matches the 12 mm x 1.5 fill point Mercedes workshop information lists for the 722.9 pan. Start it by hand and stop if it binds.
Usually you do not need it there. The 722.6 fills from a tube in the engine bay with a capped filler pipe, not from the pan. This kit is for sealed units like the 722.9, DSG, 09G and most CVTs that fill from below.
No. The kit includes the adapters, probes, O-rings and a brass quick-connect coupler with a shutoff valve. The coupler fits common manual and pneumatic ATF fill pumps.
Units from August 2003 to about June 2010 use red 236.14. Later units with the oval-indent pan and green overflow pipe use blue 236.15. Do not mix them. If you are unsure, send us your year, model and VIN.
There is no dipstick. Fill until fluid runs back out of the overflow pipe, then bring the transmission to the specified temperature on a scan tool and let it drain until it just drips before closing the valve.
The chart lists ATF105 (M10 x 1.0) for the 09G, ATF106 (M24 x 1.25) for the 02E DSG and ATF107 (M22 x 1.5) for VW/Audi CVT. Match the chart or measure your plug thread before you start.
