Additional Notes

  • The Acura TLX 2.0 AWD rear differential carries a service fill capacity of 1.7 liters, which represents the amount of fluid needed when draining and refilling during a routine service without disassembling the unit.
  • The overhaul capacity for the TLX 2.0 AWD rear differential is 1.95 liters, a figure that applies when the differential is fully disassembled, as the additional volume accounts for fluid retained in passages and components during normal service fills.
  • The TLX 3.0 AWD rear differential lists only a single capacity value of 1.7 liters, with no separate overhaul capacity figure, unlike the 2.0 AWD variant where the two values differ.
  • Under severe use conditions, the Canadian-market TLX 2.0 AWD and 3.0 AWD both share a rear differential change interval of 24,000 km, while the US-market equivalents are specified at 15,000 miles.
  • A first change only, severe condition interval is specified for the TLX 2.0 AWD (CAN) rear differential at 12,000 km, which is half the standard severe interval of 24,000 km, reflecting the practice of removing break-in contaminants from a newly filled differential earlier than subsequent changes.
  • The US-market TLX 2.0 AWD rear differential under a first change only, severe condition is specified at 7,500 miles, again representing half of the 15,000-mile severe interval applied to subsequent changes.
  • The TLX 3.0 AWD (CAN) first change only, severe interval is 12,000 km, matching the same shortened initial interval seen on the 2.0 AWD Canadian variant.
  • For the flexible on-board maintenance system condition, no change interval distance is listed for any TLX AWD variant, as the interval under that condition is determined dynamically by the vehicle's own monitoring system rather than a fixed mileage or kilometer figure.
