Read the owner’s manual first. You need to read what Toyota states for each gear, and I’m not trying to sound wise. The “shift, L” is typically used for hard engine braking. The tranny is locked in low. Lock it in low if you have a good reason not to want to shift into second. You risk overheating the tranny if you use this setting too frequently. Engine RPMs are not something I would be as concerned about as trans fluid overheating. If you’re slowly pushing a big load up a steep incline and want to keep the engine’s RPMs high to reduce strain on it, you should choose low gear. Once more, I would be more concerned with the gearbox overheating than the engine RPMs. In summary, you won’t use “shift, L” very often. Compared to a 4X4, which often has lower rear end ratios, a 4X2 with a high rear end ratio (lower, numerically) will benefit more from the “shift, L” command. The 3.91 gears are in my car. Higher gears are great for mileage while lower gears are better for hauling. Hope this was useful.

What does Toyota’s shift L mean?
Although the aforementioned four gearbox states are the most typical, some automakers offer a “L setting, too.
L is short for “If you know how to drive a manual gearbox, low gear corresponds to a gear setting of 1 or 2 in most cars.
The transmission won’t shift normally while a car is in low gear. As a result, less fuel will be injected into the engine, reducing your overall motor power. Instead, your gearbox will remain in the low gear. You’ll receive more engine torque in return.
The engine will effectively give your wheels a little more raw power instead of speed when you depress the gas pedal, which can be advantageous in some situations.
How do you turn on 4WD in a first-generation tundra?
These trucks only have occasional 4WD systems. Regardless of the terrain the vehicle is being driven on, they distribute the torque produced by the engine 50% front and 50% rear. As a result, if you drive in 4WD on pavement or any surface with strong grip while making any fast turns, the drive-terrain will become stuck, and if you keep doing it, eventually something expensive will break, such as a CV Joint, Differential, U-Joint, or even the transfer case.
The 4WD system is a shift-on-the-fly system, allowing you to potentially switch from 2WD to 4WD high range at any speed up to 60 mph. However, I don’t recommend doing this because it would put a tremendous amount of abrupt stress on the drive-terrain and soon destroy the components.
Switch from 2WD to 4WD High Range, stop the car entirely, put the transmission in neutral, wait for the engagement to finish, then switch to 4WD Low Range.
Stop the car fully, put the transmission in neutral, and then switch from 4WD High Range to 4WD Low Range.
In order to exit 4WD Low range requires you to stop the car completely once more, shift to neutral, then switch back to either 2WD or 4WD high range, depending on your needs.
Any hard surface will quickly cause damage to the drive-terrain components if you are driving in 4WD on it. To prevent the popping and scraping, you probably should have disengaged the 4WD before striking the pavement.
Can I change from D to L while I’m on the road?
Yes, driving a car with an automatic transmission while shifting from D to L is possible. Electronic transmissions are the norm today. For lowering the revs, there are limiters. Simply put, the transmission won’t change to a lower gear if the RPM for each gear is exceeded.
What does L gear serve?
On the gear change, the “L stands for “Low. What is the purpose of the “L gear? When you want the engine power to be high and the vehicle speed to be low, you choose a low gear. This lessens the strain on your brakes while enabling you to utilize the full potential of your vehicle in scenarios like towing and mountainous driving.
Does using a low gear damage your vehicle?
Long Declines: Changing to a low gear while traveling downhill aids in keeping the speed slow and steady. Your transmission won’t get damaged, and you won’t have to ride the brakes for a long time. Using low gear can assist avoid that damage because doing so can result in brake failure in the future.
When is low gear appropriate?
When traveling down a long descent or steep hill, low gear is particularly helpful. This is due to the fact that when you descend, your brakes work very hard to retain your speed and defy gravity. Under normal circumstances, this extended tension can heat up your brakes, which may even result in failure!
Can I downshift when I’m driving?
When you put your automobile in low gear, the engine essentially stays in low gear even though the speeds normally require the engine to shift to a higher ratio. This results in less speed and more torque from the engine, which might increase your car’s ability to remain put and haul heavier loads. Many auto transmission automobile owners seldom shift down into the low gear. This is due to the fact that either they are unaware of its significance or have never encountered a situation in which it would be useful. However, you might find it useful if you know how to use it and what low gear is for. Here are a few justifications for driving in low gear on an automated vehicle.
Towing Large Loads
If you don’t drive in “low gear,” you risk damaging your transmission if you are towing a large boat or if your truck’s flatbed is loaded down with bulky goods or equipment. This is so that it can function and shift while supporting the vehicle’s built weight. Significant weight changes may have a negative impact on the transmission. The complete transmission maintains the engine running at faster RPMs to handle that increased load when towing heavy loads in low gear.
Secondly, Steep Inclines and Declines
When navigating steep slopes or mountains, drivers of autonomous vehicles may decide to manually shift into a low gear. In order to give your car a little more power, or engine torque, to accomplish the climb without taxing the engine, you can manually shift your engine into low gear as you are driving up a steep slope. On the other hand, driving slowly and steadily when descending a steep hill can prevent you from riding your brakes or damaging your drivetrain.
What does my glove box’s Set button do?
The “SET button can be utilized while changing or altering tire pressure, changing tire size, rotating tires with differing tire pressures in the front and rear, or replacing tires.
Tundra has 4WD or AWD.
A 6-speed electronically regulated automatic transmission is standard for all Tundra variants. The electronic, on-demand 4WDemand part-time four-wheel drive (4WD) system was installed in this truck.
Can you change from 4L to 4H while operating a vehicle?
An additional excellent driving surface for 4WD. In certain circumstances, you could even swap between 4hi and 4Lo. Deep mud is a surface with high resistance that puts a lot of strain on your clutch and drivetrain. Modern 4WDs allow you to securely convert from 4Lo to 4Hi while you’re driving, but you must always stop before switching from 4Hi to 4Lo.
What gear should I shift into for an ascent?
As soon as you leave the paved path, put the car in low range. You’ll use a variety of gears as you navigate the varied terrain common to many off-road scenarios. Higher gears are required in some circumstances, whereas lower gears are needed in others. Higher ratios and easy throttle mean less torque and the least amount of tire spin, as a general rule of thumb. More torque and the greatest amount of wheel spin are produced by using lower gearing and more throttle.
When traveling downhill, use first gear as your main means of braking. Engine braking reduces the amount of time you need to press the brake pedal, keeping your wheels moving. It’s crucial to be able to steer if the wheels are moving when starting a steep downhill run. Utilize our wheel alignment service to verify that your wheels are correctly aligned.
Uphill: In order to reduce torque, which also reduces tire spin, approach uphill conditions with the necessary amount of momentum, a higher gear (third in an automatic transmission), and less throttle. The last thing you want to happen is to start climbing the slope and then lose traction and start spinning your wheels. Simply said, you’ll end up damaging the hill’s surface, making it more difficult to climb it again later. Use second or third gear when climbing a steep slope if your vehicle has a manual transmission, and don’t change gears once you’ve started the ascent.
Failed Climb: Put the car in reverse to keep the wheels moving and allow for natural engine braking. Always utilize this equipment while backing up after an unsuccessful ascent for the greatest control and secure descent. Never roll back down as heavier cars gain a lot of momentum rapidly and things can quickly spiral out of control without the assistance of your engine for brakes.
Is using an automatic transmission while moving a bad idea?
A spinning coupling mechanism in the transmission that can prematurely fail if it becomes worn from a quick gear change can be severely damaged by shifting too quickly while your automobile is still moving. Before changing into a different gear, always come to a complete stop.
Does a downshifting automatic transmission harm it?
The car slows down when an automated transmission is downshifted manually into a lower gear. Lower gear ratios provide you more control of your car in some driving situations while reducing the output speed of the transmission.
The transmission is prevented from automatically upshifting by shifting into “L or first gear”1. When you lift your foot from the accelerator, an automatic downshift, commonly referred to as engine braking, occurs.
When a slower rotating engine engages a faster revolving transmission, engine braking occursbasically, reverse acceleration. When you lift your foot off the accelerator, the throttle closes, reducing engine air flow and creating a significant vacuum in the intake manifold.
Without the driver applying the brakes, your car will slow down as pistons working in high vacuum lose power, lowering engine RPMs. Slowing the car down using engine braking may increase the life of your brake pads and rotors because you aren’t pressing down on the brake pedal as frequently.
On the other hand, automatics with locking torque converter clutches or overdrive transmissions have gear ratios higher than high gear or direct drive (1:1, one transmission rotation for every engine rotation). In addition to allowing the transmission to downshift automatically when accelerating at highway speeds, this lowers engine RPMs at highway speed to improve fuel efficiency.
