Additional Notes

  • The Dennis Eagle Elite 6 (2014-2022) carries an automatic transmission fluid capacity of 28 liters under standard configuration, a volume consistent with heavy-duty commercial vehicle transmission sumps where large fluid reserves support sustained thermal management during demanding duty cycles.
  • When the Elite 6 is fitted with a retarder, the automatic transmission fluid capacity rises to 30 liters, reflecting the additional fluid volume required to service the retarder circuit integrated into the transmission assembly.
  • A check interval of 1 month or 250 hours is specified under normal use conditions, whichever comes first, indicating that fluid level and condition monitoring is expected on a relatively frequent basis relative to the full drain interval.
  • The change interval under normal use is set at 48 months or 6,000 hours, a long-cycle schedule that reflects the fluid's expected service life within a sealed heavy-duty automatic transmission operating under defined normal conditions.
  • The 6,000-hour change threshold is particularly relevant for vehicles accumulating high annual operating hours, as the hour-based limit may be reached well before the 48-month calendar interval in intensive fleet applications.
