Acura TLX, UB5, UB6, UB7 (USA / CAN)

Automatic transmission fluid capacity & service interval

Acura TLX, UB5, UB6, UB7 (USA / CAN) models require automatic transmission fluid with an overhaul capacity range of 7,3-9,1 liters and a service fill capacity range of 3,2-4,8 liters. Service intervals follow a flexible on board maintenance system. The data covers 6 configurations.

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

Additional Notes

  • All six configurations listed share the same automatic transaxle designation, meaning the transmission and final drive are housed in a single combined unit rather than separate assemblies.
  • The Acura TLX 2.0 front-wheel-drive configurations, covering both USA and CAN markets, carry an overhaul capacity of 7.3–8.3 liters. This figure represents the total fluid volume required when the transaxle is fully disassembled and refilled from dry.
  • The service fill capacity for the TLX 2.0 front-wheel-drive variants is 3.2–4.3 liters, which is the partial volume replaced during a routine fluid change without a full teardown. The gap between service fill and overhaul capacity reflects the fluid that remains trapped in the torque converter and valve body during a standard drain procedure.
  • The TLX 2.0 AWD configurations show a higher overhaul capacity of 7.8–8.8 liters compared to the front-wheel-drive 2.0 variants, a difference attributable to the additional fluid volume required by the rear differential and transfer components integrated into the AWD drivetrain.
  • The AWD 2.0 service fill range of 3.7–4.8 liters is similarly elevated above the front-wheel-drive 2.0 service fill, consistent with the added fluid passages associated with the all-wheel-drive hardware.
  • The TLX 3.0 AWD carries the largest overhaul capacity of the three configurations at 8.2–9.1 liters, reflecting the greater internal volume associated with the larger 3.0-liter engine pairing and its corresponding transmission calibration.
  • The 3.0 AWD service fill range of 4.1–4.8 liters has a narrower spread than the 2.0 AWD service fill range of 3.7–4.8 liters, indicating a tighter variance in the volume recovered during routine fluid changes on the 3.0 AWD transaxle.
  • All configurations specify a flexible service interval governed by the on-board maintenance system rather than a fixed mileage or time schedule. The vehicle's monitoring system calculates the appropriate change interval based on operating conditions detected during use.
  • The USA and CAN market variants within each engine and drivetrain pairing share identical capacity specifications, with no regional difference in fluid volumes across any of the six listed configurations.
