My name is David Northcutt and I am a master Mercedes technician. I have been with Mercedes Benz for 25 years. I developed this tool to help us diagnose shift issues in the Mercedes Benz 722.6 and 722.9 transmissions. We have been using these for the past few years. This product allows us to air test the clutches and brakes in the Mercedes Benz 722.6 and 722.9 transmissions. The 722.6 plate features the gear application chart engraved directly on it for easily referencing which shift members are involved with each gear. Hopefully you will find it helpful as well.
