Acura TL 2004-2008 H5 Transmission Specifications

The 2004-2008 Acura TL h5-transmission requires Honda/Acura Genuine ATF-Z1 or equivalent automatic transmission fluid. Using the correct fluid is critical to ensure proper lubrication, cooling, and shifting performance. The transmission capacity is approximately 2.9 quarts (2.7 liters) for a fluid change and 7.4 quarts (7.0 liters) for a full flush.

Common symptoms include harsh or delayed shifting, slipping gears, transmission overheating, unusual noises (e.g., whining or grinding), and the illumination of the Check Engine or Transmission Warning light. These issues may indicate worn clutch packs, solenoid failures, or fluid degradation, and should be addressed promptly to avoid further damage.

Acura recommends replacing the transmission fluid every 30,000 to 60,000 miles, depending on driving conditions. Severe driving conditions, such as frequent towing, stop-and-go traffic, or extreme temperatures, may necessitate more frequent fluid changes to maintain optimal transmission performance.

Yes, a transmission fluid change can be performed at home with the proper tools and knowledge. You will need a jack, jack stands, a drain pan, and the correct ATF-Z1 fluid. However, a full flush requires specialized equipment and is best performed by a certified technician to ensure all old fluid is removed and the system is properly pressurized.

The torque specification for the h5-transmission drain plug is 36 lb-ft (49 Nm). Over-tightening can damage the transmission case, while under-tightening may lead to fluid leaks. Always use a calibrated torque wrench for accurate results.
