What is the l in prndl?

The "L" in the PRNDL stands for "Low" or "Low Gear." When the gear lever is shifted into the "L" position, the vehicle operates in a lower gear ratio, which provides higher engine speed and more power for climbing steep hills, towing heavy loads, or descending steep slopes at a controlled speed. This gear position is typically used in situations where increased torque is needed, such as off-roading or driving on slippery surfaces. By selecting the "L" position, the driver has more control over the vehicle's speed and can prevent the transmission from shifting into higher gears.
