Additional Notes

  • The Ossa Explorer 280i carries a transmission fluid capacity of 0.38 liter for the 2012-2013 model years, while the 2014-2015 model years share the larger 0.45 liter capacity used across all 250i variants. This difference reflects a revision to the 280i transmission assembly between those production periods.
  • The 0.45 liter figure applies as a service fill capacity, representing the amount of fluid the transmission holds during a standard drain-and-refill procedure rather than a full overhaul measurement.
  • All configurations share an identical three-stage service schedule structure: an initial service change at 5 hours, a second change at 12 hours, and normal ongoing intervals of a check at 30 hours and a change at 60 hours.
  • The initial service change at 5 hours of operation is a break-in interval. New transmission components generate fine metallic particles during early use, and a short first-change interval removes that contaminated fluid before it can cause accelerated wear.
  • The second change at 12 hours serves as a follow-up flush after the initial break-in period, addressing any residual particulate matter that remains after the 5-hour change before the transmission transitions to the normal 60-hour change cycle.
  • Under normal use conditions, the fluid level is checked at 30 hours and the fluid is fully replaced at 60 hours. The intermediate check interval allows for early detection of fluid loss or contamination without requiring a full drain at that point.
  • The 250i and 280i designations refer to different engine displacements within the Explorer range, yet both share the same 0.45 liter transmission capacity for 2014-2015, indicating a common gearbox unit was used across both variants in those years.
