AMG GTC - Transmission Service questions
Last edited by 2gosu; Nov 18, 2025 at 06:02 PM.
The recommended every 30,000-mile service consists of replacing both fluids: approximately 7.8 liters of hydraulic ATF for the transmission section and 3.8 liters of GL-5 gear oil for the differential.
These two fluids operate in completely separate chambers within the transaxle, and there is no fluid exchange or mixing between the transmission and differential compartments.
You can find lots of info on the Transaxle service here: https://mbworld.org/forums/coupe-roa...e-caution.html
