What is L in Acura TL?
The L on an Acura TL’s gear selector stands for Low — a low-range gear setting that emphasizes engine braking and greater control at low speeds or on steep grades.
Understanding the L position in the TL
In automatic transmissions, L keeps the gearbox in a lower gear ratio. This means the engine runs at higher RPMs for the same road speed, providing stronger engine braking and more immediate power response when starting from a stop or climbing slow grades. Some TLs implement this as a distinct L position on the shift knob; others rely on lower-numbered gears (like 2 or 1) or a sport/limited mode to emulate low-range behavior. Always consult the owner’s manual for your specific model year, as features can vary between generations and trims.
When to use L
Use L in situations where you need controlled speed and stronger engine braking, not for regular highway cruising.
Here are common scenarios where selecting L can be helpful:
- Descending long, steep grades to rely on engine braking and reduce brake wear
- Slow-speed maneuvers in parking lots, driveways, or when towing light loads, where maintaining a low gear helps control speed
- Driving in slippery conditions where keeping RPMs higher can help prevent wheel spin and maintain traction
- Starting from rest or climbing steep grades where more immediate torque is preferable to smooth shifts
Note: If your TL does not have a distinct L gate, you can achieve similar behavior by using lower gears (2 or 1) or by selecting a gear-limiting mode (such as D3) depending on the transmission. Refer to your manual for exact operation on your model.
In everyday driving, leave the selector in Drive (D) for smooth shifts and better fuel economy. Engage Low only when hill descent, engine braking, or precise control at very low speeds is needed.
TL variations and compatibility
The Acura TL line spanned several generations, and the gear selector layout evolved over time. Some model years retain a dedicated L position on the shifter, while others rely on gear-limiting options (like 2, 1 or D3) to replicate the low-range behavior. Always verify your exact model’s operation in the owner’s manual to avoid confusion.
Summary
The L designation on the Acura TL stands for Low, a gear setting designed to keep the transmission in a lower range for increased engine braking and control at low speeds or on hills. It is not intended for everyday highway driving and should be used selectively according to your vehicle’s manual and you specific model year.
