Mercedes-Benz Sprinter, 906 (USA / CAN)

Additional Notes

• Two distinct automatic transmission fluid capacities appear across the Mercedes-Benz Sprinter 2500/3500 906 specifications: 7.1 liters and 9 liters. The 7.1-liter figure represents a partial service fill, typically associated with a drain-and-refill procedure that does not evacuate the torque converter, while the 9-liter figure reflects a fuller fill volume used when the transmission is more completely drained or overhauled.
• For 2010-2012 OM642 models, the 9-liter capacity is split into two distinct sub-specifications based on production number. Units at or above production number 2834527 with option code A89 carry one 9-liter entry, while units up to production number 2834526 without code A89 carry a separate 9-liter entry. Both share the same 77,500-mile change interval under normal use conditions.
• The 2012-2015 OM642 configuration presents two separate change intervals depending on which capacity applies. The 7.1-liter fill is paired with a 60,000-mile interval, while the 9-liter fill carries a 77,500-mile interval, both under normal use conditions.
• A dedicated initial service interval appears for the 2015-2016 OM642 and the 2014-2016 OM651 configurations. In both cases, the initial service calls for a 7.1-liter fill at 40,000 miles, which is half the 80,000-mile normal-use interval assigned to the same 7.1-liter capacity in those same year ranges. Initial service intervals are typically applied to new transmissions to remove factory fill fluid and any early wear particles before the standard service schedule begins.
• The 80,000-mile normal-use interval for the 7.1-liter fill appears only in the 2015-2016 OM642 and 2014-2016 OM651 specifications. Earlier and later year ranges for the same 7.1-liter capacity use either 60,000 miles or 77,500 miles, reflecting changes in service scheduling across production periods.
• From 2016-2018, both the OM642 and OM651 engines share identical automatic transmission fluid specifications: a 7.1-liter fill and a 9-liter fill, each at a 77,500-mile normal-use interval. No initial service interval is listed for either engine in this period, distinguishing the 2016-2018 entries from the preceding 2014-2016 and 2015-2016 configurations.
• The OM651 engine, a four-cylinder diesel, enters the Sprinter 906 automatic transmission specifications starting with the 2014-2016 period, while the OM642, a V6 diesel, covers the full 2010-2018 span. Despite the difference in engine architecture, both engines share the same capacity values and, within overlapping years, the same service intervals.
