722.9 Transmission Fluid Fill and Power Drain Service Kit

Pressure tank included. From 2003 to 2016, 7-speed automatics require filling from under the car. For use with Red or Blue Fluid. Video instructions included.

Effective 1/24/25, we will no longer include the pressure tank. You can get your own at your local hardware store and save on this kit and shipping!  It comes with a special fitting attachment that includes two (2) shut-off valves ( to control spills) and a clear filter to make absolutely sure you are putting clean fluid into the pan. It includes over 5 feet of hose ( 30 inches which are clear so you can see the flow rate, plug extra clear hoses to complete a power drain ( explained in the video instructions).

Product Details

Don't flush - do a power drain of the entire system

1. This kit can top off your transmission when you discover your fluid is low.

2. This kit can fill your transmission after doing a fluid drain and filter change.

3. The included extra-clear hose and instructions can be used to "power drain" all the fluid out, including what is in the valve body, torque converter, and transmission cooler.  

Now included: If you do plan to use this kit to do a full power drain (#3 above) we are including  the two o-rings for the transmission cooler line at no extra charge. PLEASE NOTE: These orings work on most early version models but may not work on all or on some models after 2010. NOTE TO 4MATIC OWNERS: You will be able to use this pressure tank to fill your transmission, but the power drain function will NOT work due to complexity of the 4matic. 

Extra hoses and o-rings to complete a full power drain of the fluid if you so choose.

Custom attachment wand not available anywhere else. Includes two valves to reduce spills and a pre-filter to prevent contaminants from entering your transmission. 

 

PRESSURE TANK INCLUDED. It is almost impossible to fill the 722.9 transmission accurately without some type of pressure tank that can hold transmission fluid and "force" it up into the transmission. The one we provide has proven to be very efficient and reliable. The pressure release on the tank will prevent major fluid spills ( mark my word).

This pressure tank can also fill your rear end. Make sure you clean it thoroughly when changing fluids. A rear-end fill wand is included at no extra cost. 

If you have the early 2003 to mid-2010 transmission, this would be the time to upgrade to the newer deeper pan, the Smart Triple Media Mercedes filter. Kent has assembled a complete upgrade kit and video instructions to make it easy to do this yourself. We also have a money-saving Combo kit for the full service. See related products below:
