Additional Notes
- The automatic transmission fluid capacity for the 300D, W189 is specified as a range of 8 to 9 liters, which reflects a service fill figure rather than a fixed single value, accounting for variation in residual fluid retained within the transmission assembly during a drain and refill procedure.
- The 8 to 9 liter range is notably substantial for an automatic transmission service fill, consistent with the large-displacement, full-size luxury vehicle architecture of the W189 platform produced from 1957 to 1962.
- The fluid change interval for the 300D, W189 automatic transmission is set at 36,000 km or 12 months, whichever occurs first, under normal use conditions, meaning both a distance threshold and a time threshold govern when a fluid change is due.
- The 12-month time component of the 36,000 km / 12-month interval means that even low-mileage operation does not extend the service period beyond one year under normal use conditions.
