Start the engine, allow it to stabilize and idle for perhaps 15 seconds, shift into gear, wait a few seconds for the transmission to fully engage then drive the vehicle up to temperature gently.
Does idling warm up transmission?
Idling the engine for the first 30 seconds to 1 minute is not to warm the engine up but rather to get the oil circulating through the engine. If you idle an automatic, the transmission does warm up a bit due to the torque converter. In a manual, you have to drive the car in order to warm the transmission up.
How long does a transmission take to warm up?
So, when it’s extremely cold outside, start the engine, and let it idle for a minute or so before putting it in gear or under load. This allows engine oil and transmission fluid to circulate and lubricate. Then shift into gear and let the engine and transmission warm another 30 to 60 seconds.
Can a transmission be too cold?
The ideal temperature for it is 175 degrees, plus or minus 25 degrees, and when the transmission gets below zero degrees, it gets too thick. The fluid can also fail to lubricate parts when it is too cold, wearing parts down unnecessarily.
How do you warm up an automatic car?
How to Properly Warm Up Your Car
- Get into your car. Turn the ignition on but don’t start the engine just yet.
- In 3-5 seconds, you should hear the fuel pump priming the engine. Start the car when this happens.
- Idle for about 10-20 seconds at the most.
- Slowly ease out of your parking spot and ease into driving.
What is active transmission warm up?
Active transmission warm-up systems are used by automotive manufacturers in effort to increase powertrain efficiency and decrease fuel consumption. These systems vary from one manufacturer to another, but their main goal is to capture waste heat from the powertrain and accelerate transmission fluid warm-up.
How long should I let my car run before checking the transmission fluid?
Let it run for about 5 minutes so that it can warm up. Some car manufacturers will recommend you turn the engine off before checking the transmission fluid, but most don’t recommend this.
Do you check your transmission fluid when it’s hot or cold?
Transmission fluid however is best checked when your vehicle is running. The reason for this is that transmission fluid, like any fluid expands when it’s warm and contracts when it’s cold. You’ll get a better reading of how your transmission fluid levels are in your vehicle if you check it when it’s running warm.
What is the normal operating temperature of a transmission?
Normal operating temperature for an automatic transmission is about the same as the engine temperature, i.e., about 195°F. The temperature inside the torque converter, while pulling a big load from a standing start, could easily rise above 350°F.
Why is it bad to warm up your car?
By letting your car sit to warm up, it’s actually putting extra fuel into the combustion chamber, which can get onto your cylinder walls. Because gasoline is an excellent solvent, too much on your cylinder walls can dissolve the oil that lubricates your cylinders, leading to shorter life on crucial components.
What are the symptoms of low transmission fluid?
Signs of Low Transmission Fluid
- Warning light.
- Transmission overheating.
- Difficulty in shifting gears.
- Transmission fluid leakage.
- Generation of unusual sounds.
- Transmission slipping problems.

Why does my car jerk when shifting gears with an automatic transmission?
Automatic transmissions that shift hard, jerk or shake during a shift change may mean your transmission fluid needs changed or fluid level is low. In manual transmission vehicles, abnormal gear shifts could indicate damaged gear synchros, worn clutches or other, more severe issues.
How often do you need to change your transmission fluid?
Most manufacturers recommend replacing transmission fluid every 30,000 to 60,000 miles. If you tow, or do mostly city driving with constant changes of gears, it may be wise to change your ATF even more often. Here’s why. Your automatic transmission has a lot of moving parts.
Is it bad to start your car and drive right away?
Auto experts today say that you should warm up the car no more than 30 seconds before you start driving in winter. “The engine will warm up faster being driven,” the EPA and DOE explain. Indeed, it is better to turn your engine off and start it again than to leave it idling.
Does cold weather affect automatic transmission?
Transmission fluids are also affected by cold temperatures. Since transmission fluid’s ability to flow does not directly impact a vehicle’s ability to start, cold-temperature transmission fluid performance is not foremost in the minds of consumers.
What happens if you don’t warm up your car?
It lets the richer gasoline mixture strip the oil from the engine’s cylinder walls, increasing engine wear. A rich mixture from a cold engine can damage your catalytic converter. Your vehicle pollutes a lot more when idling in cold weather. Long periods of idling are illegal in most places and could get you fined.
