What is the function of L in corolla s gear


Hi, I have spent some time researching this, and have come to the following evaluation:
Assuming your Toyota Corolla S is an automatic:

P, R, N, D, these are all letters on your automatic transmission that you're probably familiar with. However, you might rarely, if at all, shift into "L" on the gear shift. So what does this letter stand for? And should you use it?
L stands for low gear. When your car is in drive, or D, the automatic transmission will shift through the gears as your speed increases. When your car is in low, or L, the transmission won't shift. Instead, it remains in a low gear, and less fuel is injected into the engine. This gives you less speed, but what you sacrifice in speed you make up for in engine torque. Basically, using low gear gives the engine more power.
Torque is useful when you're towing something with your automatic. Towing requires more torque, but if you tow in drive it puts more strain on your engine as the transmission cycles through the gears. Keeping it in low gear lets you keep the torque, which makes towing easier, and reduces the stress on your engine. Another reason you might use low gear is for driving up a hill in order to give your engine the power to get up the hill without over-stressing it. Low gear is also useful for driving in snow or on icy roads, because it reduces your speed and gives you more control over the vehicle.

I hope this helped, please feel free to write a testimonial if it did :)

1993 Ford Explorer 5 speed driving it without the clutch slave without the clutch and without the 5 speed gear shifter how to get into 3rd gear


the process involves plenty of hydraulic fluid as well as gears and clutches.
If you have an automatic transmission, and it "slips" while you are driving it-that is, the car engine revs without the power going to the wheels-the most common cause (though not the only possible cause) is low transmission fluid. If the slipping is caused by low fluid, it will get worse as the transmission gets hotter.

Why when i put in drive and go it goes into 1 or2 or drive by it self while driving


It always starts out in first, it's a 3 speed automatic, that's what automatics do. they start out in first and at about 15-20 miles per hour , they shift to second gear, and when the speed is about 35-45 MPH, the transmission automatically shifts into third gear, or Drive.

Bigger automatics have 4 or more speeds. Till recently, 4 speeds were the norm, and fourth gear was often dubbed Overdrive, as it allowed the engine to run slower in 4th gear, than it had to maintain speed in 3rd gear, drive. It's good, it increases your mileage per gallon of gas, so you save that way, but like all things more complicated, they cost more to fix when something goes wrong.

My 2003 cadillac cts automatic transmission will not change gears pulls off slowly but will reach high speed


please do not have your transmission flushed , have someone take the oil pan off and replace the filter as well and what ever trans oil you take out replace it as well . no automotive repair shop will warrenty your trans if it should suddenly stop working , but just for your satisfaction ask the transmission repair shop who flushs trans if they guarantee it and have them put it in writing . ive never understood why flush dirty oil and leave the dirty filter in the trans , it collected all dirt and metal wear which is what is causing it to plug up causing it to restrict the oil flow

Slower engine speed in 4wd mode, 1st or 2nd gear (auto trans)


mcdevito75 here, I would figure yes, if your shifting while in motion, definetly yes, when you shift your changeing gear ratios in the 4 wheel drive or the transmission, this will cause the engine to slow but also make the gas pedal moe responsive.If you feel or hear this slowing down of the engine while standing still (at a red light) it"s most likely the computer contolled sensor in the tranny. I woulkd still check with my local shop for their advice too.

Transmission Speed Sensor Inconsistency


Check the 10 wire connector going into the transmission for water or corrosion. This could cause inadvertant shifting but would also probably set the check engine light. The throttle position sensor could also cause this. Speed sensors screw into the transmission from the outside and would cause a limp in condition where it wouldn't shift out of second gear.
