Additional Notes

  • The Mercedes-Benz T-Class W420 (EU) manual transmission fluid specifications cover the transaxle unit across all listed variants, with capacity values appearing in two distinct figures: 2 liters and 1.5 liters.
  • A 2-liter capacity is the value associated with a full overhaul or dry fill of the transaxle, representing the total fluid volume the unit holds when completely empty.
  • The 1.5-liter capacity listed alongside the 2-liter figure for the T 160 d (420.823) reflects a service fill level, which is the amount of fluid added during a routine drain-and-refill without fully disassembling the unit.
  • The same dual-capacity pattern of 2 liters and 1.5 liters appears on the T 180 d (420.833), indicating both variants share an identical transaxle fluid volume structure under normal use conditions.
  • The T 160 (420.853) and T 180 (420.863) petrol variants each carry only a single listed capacity of 2 liters for the manual transaxle under normal use conditions, with no secondary service fill figure present in the specifications.
  • All six specification rows are designated under normal use conditions, meaning the listed capacities apply to standard operating environments rather than severe or extended-duty service.
  • The diesel variants, the T 160 d and T 180 d, are the only configurations in the specifications where two separate capacity values appear, distinguishing a full fill from a partial service refill within the same transaxle system.
