DIY time! We change the Gear Box and Torque Converter oils of our Mercedes 722.9 automatic transmission van for the first time. We make mistakes such as forget to buy a new oil plug for the TC (torque converter) and use wrong size torque wrench but manage to complete the full service eventually ???? feels like a dramatic maintenance operation ????️

This gear box is also known as MB 722.9 7G Tronic and NAG2, in our camper van it is paired with a 4 cylinder, 2.1 diesel engine.

Following videos are extremely helpful and explain the full maintenance procedure in detail. Please have a look at them if you plan to complete this service on your own:
