Acura TLX (USA / CAN)

Additional Notes

• The Acura TLX 2.4 uses a transaxle-type automatic transmission, while the 3.5 and 3.5 AWD configurations use a conventional automatic transmission. This distinction reflects the different drivetrain architectures between the four-cylinder and V6 variants, and the terminology used in the specifications follows that mechanical difference.
• The 2.4 transaxle capacity of 3.9-4.1 liters is expressed as a range rather than a fixed value, which is typical of service fill quantities where the final level is confirmed by a fill plug or dipstick rather than a precise measured volume. The 3.5 and 3.5 AWD transmission capacity is listed as a fixed 3.3 liters, indicating a more defined service fill quantity for those units.
• Under severe use conditions, the Canadian-market TLX 2.4 carries a 48,000 km automatic transmission fluid change interval, while the US-market equivalent is set at 30,000 miles. These two figures are not equivalent in distance, meaning the Canadian interval is somewhat shorter when converted, reflecting a regionally differentiated service schedule rather than a simple unit conversion.
• A separate severe-use interval applies specifically to the first fluid change on the TLX 2.4. In Canada, the first change under severe conditions is due at 64,000 km, compared to 48,000 km for subsequent severe-use changes. The US equivalent sets the first severe-use change at 40,000 miles versus 30,000 miles for later intervals. This extended first-change interval is consistent with break-in fluid practices, where the initial factory fill is retained longer before the standard recurring schedule begins.
• The same first-change extension applies to the 3.5 and 3.5 AWD configurations. Under severe use, the first fluid change is due at 64,000 km in Canada and 40,000 miles in the USA, with subsequent severe-use changes at 48,000 km and 30,000 miles respectively. The first-change interval is therefore approximately one-third longer than the recurring severe-use interval across all engine variants.
• All three configurations — the 2.4, 3.5, and 3.5 AWD — share an identical set of interval structures across both markets: a recurring severe-use interval, a first-change-only severe-use interval, and a flexible interval governed by the on-board maintenance system. The on-board maintenance system rows carry no fixed mileage or kilometer value, as the system calculates change timing based on operating conditions rather than a predetermined distance.
• The 3.5 AWD shares the same 3.3-liter transmission fluid capacity and identical service intervals as the front-wheel-drive 3.5 across all use conditions and both markets. The AWD system itself is not reflected in the automatic transmission fluid capacity figures listed in these specifications.
