Mercedes Transmission Fluid: Separate 722.9 and 9G-Tronic Products
Compare a red-fluid 722.9 service kit with a 725.0 9G-Tronic fluid bottle. Verify the installed transmission and exact variant before ordering.

Identify the transmission before choosing fluid
Start with the installed transmission and its required fluid reference. The 722.6, 722.9 and 725.0 designations identify different transmission families; a Mercedes model badge or the number of gears alone does not establish the correct service product. Confirm the vehicle configuration with the retailer before ordering.
Choose the red-fluid 722.9 kit only for the matching variant
ECS kit 2212770195KT6 is listed for supported 722.9 applications without code A89, using red fluid. Its fixed package includes nine one-liter bottles of Liqui Moly Top Tec ATF 1800, a guide tube, pan gasket, drain washer, torque-converter drain plug, six pan bolts and a filter/gasket component. Nine liters describes the supplied amount, not a universal service-fill quantity. Check the production-date and variant conditions in the ECS application data. Do not substitute this kit for an A89 or 725.0 application.
Choose the 9G-Tronic bottle for a confirmed 725.0 application
Genuine Mercedes-Benz 002989060312 is a one-liter bottle. ECS identifies its gold fluid as MB 236.17 / ATF D971 for matching 725.0 9G-Tronic applications. It is a different product from the red-fluid kit above. Determine the required quantity for the planned operation separately; one bottle is not a complete service-kit recommendation.
Complete the order with the exact configuration
Use the corresponding offer below each product section after confirming the transmission, fluid requirement and variant. No 722.6 product is recommended by these two listings. Follow the applicable service instructions for the work; EWP compares products and refers shoppers to merchants, who handle the transaction and final application confirmation.

Mercedes-Benz Steering Fluid: Match the Required Specification

Founder, European Wholesale Parts
Lee Shahin founded European Wholesale Parts in Pleasanton, California, after 18 years in the Mercedes-Benz and BMW parts trade. He came to the parts side from the shop floor: he opened a European repair shop in Northern California in the early 1990s, specialising in Mercedes-Benz and BMW, and grew it with his wife Laurie into a parts and delivery operation serving body shops and independent repair facilities across the region. Nearly two decades at the parts counter taught him where the expensive mistakes happen, and most of them are fluids: the wrong coolant in an aluminium block, an oil without the sheet approval the engine was designed for, a transmission topped with the wrong ATF. That is what he writes about here. Every article names the manufacturer specification by its exact designation, explains what the wrong fluid does mechanically, lists products that carry the approval, and gives the capacity and interval for the models and years the specification covers. When a reader needs a part sourced, the quote desk at European Wholesale Parts is where Lee and Laurie still answer the phone.
