Acura RL, KA9, KB1, KB2 (USA / CAN)

Transfer case fluid capacity & service interval

Acura RL, KA9, KB1, KB2 (USA / CAN) models utilize transfer case fluid with a capacity range of 0,43 to 0,45 liters. The data covers 2 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

TypeSpecifications
RL 3.7 SH-AWD (USA) (2011-2012)
  • Use: Normal
  • Capacity 0,43-0,45 liter
RL 3.7 SH-AWD (USA) (2009-2011)
  • Use: Normal
  • Capacity 0,43 liter

Additional Notes

  • The Acura RL 3.7 SH-AWD (USA) for 2009-2011 carries a transfer case fluid capacity of 0.43 liter under normal use conditions. A figure this small is characteristic of a compact transfer unit rather than a standalone gearbox assembly, reflecting the space constraints of an integrated all-wheel-drive system.
  • For the 2011-2012 model year range, the transfer case capacity is listed as 0.43-0.45 liter under normal use conditions, introducing a narrow tolerance band absent from the earlier specification. The 0.02-liter spread likely accounts for minor variation between production units or fill procedures rather than a fundamental design change.
  • The year 2011 appears in both specification rows, meaning two distinct capacity figures are associated with that single model year depending on which production variant is referenced. The earlier 2009-2011 entry uses a fixed 0.43-liter value, while the 2011-2012 entry introduces the 0.43-0.45-liter range.
  • Both rows carry the note designation "transferbox," which identifies the component as the transfer case unit specifically, distinguishing the fluid fill from any front or rear differential service that may be performed separately on the SH-AWD drivetrain.
