Additional Notes

  • The Honda Odyssey RL4 3.5 V6 carries a service fill capacity of 3.1 liters for its automatic transaxle fluid, a figure that reflects a standard drain-and-fill procedure where only the fluid released by opening the drain plug is replaced, leaving residual fluid in the torque converter and valve body.
  • The overhaul capacity of 7.6 liters represents the total fluid volume required when the transaxle is fully disassembled, meaning the torque converter is emptied and the entire unit is refilled from a dry state.
  • The difference between the 3.1-liter service fill and the 7.6-liter overhaul capacity indicates that a routine drain-and-fill replaces roughly 40 percent of the total fluid volume held within the transaxle assembly.
  • Under severe use conditions, the 2005-2010 Odyssey 3.5 V6 automatic transaxle fluid is specified for a change interval of 30,000 miles, with 3.1 liters required to complete that service fill.
  • A separate interval applies when the vehicle is equipped with an on-board maintenance monitoring system, under which the flexible use condition governs the change timing rather than a fixed mileage figure, while the same 3.1-liter service fill capacity and 7.6-liter overhaul capacity remain in effect.
  • The 3.5 V6 specification applies uniformly across the full 2005-2010 model year range, meaning no variation in fluid capacity or severe-use interval exists between those years for the automatic transaxle.
