How do I check my transmission fluid?

Pull out the dipstick, wipe it clean, replace it slowly, and then pull it back out. Check the fluid level—how high the fluid comes up on the dipstick—against the "full" and "low" or "fill" marks on the dipstick. The color of transmission fluid can tell you a lot about the health of your car's transmission.

Do you check transmission fluid when warm or cold?

If you're going to be checking the transmission fluid level at home, it's a good idea to warm up the car before you do so. If the car is checked while the engine is cold, it might give an inaccurate reading when you use the dipstick.

Do you check transmission fluid with the car running?

Step 1: Leave the engine running and open the hood to your car. The car must be warm when you check transmission fluid. Step 2: If you have an inline engine, look behind your oil dipstick, toward your windshield, to locate the transmission fluid dipstick.

How do I know if my transmission fluid is low?

What happens if you drive with low transmission fluid?

Sometimes, a malfunctioned transmission might trigger leaks of the transmission fluid. It causes the levels of the fluid to go low, which affects the functionality of the vehicle. Driving through low transmission fluid levels might result in permanent and costly vehicle damages and expensive repairs.

How To Check Automatic Transmission Fluid

Can I just add transmission fluid?

Insert long funnel into automatic transmission fluid dipstick hole. Carefully add automatic transmission fluid in small increments and recheck level each time until fluid level reaches "warm" line. CAUTION: DO NOT OVERFILL OR SPILL AUTOMATIC TRANSMISSION FLUID ON HOT ENGINE PARTS!

Will check engine light come on for low transmission fluid?

There are many, many reasons that the check engine light may come on in you car, truck or SUV. A malfunctioning sensor, low tire pressure, low transmission fluid and so much more will cause the light to come on.

What does low transmission fluid sound like?

If you're like many drivers, you often forget to check the fluid levels in your vehicle, and if the fluid level in your transmission is too low, you will notice a gurgling noise. This noise is caused by the excess air in your transmission line.

Can transmission fluid be low without a leak?

The leak may be small and hard to detect, but it will be there. You probably think there's no leak because you don't find a pool of fluid underneath your car, however it may only be leaking when the vehicle's being driven as that's when fluid is being circulated and under pressure.

How long can a car run without transmission fluid?

Technically, the vehicle can still be driven with low to no transmission fluid for 10 to 15 miles. However, doing so will lead to transmission system failures and can damage the car permanently.

What happens if you overfill transmission fluid?

If you overfill it, the transmission will experience hard shifting and slippage. Another consequence of overfilling your transmission is that it will cause the fluid to lose its lubricating properties. It could also lead to the entire system blowing up and not functioning.

What does yellow transmission fluid mean?

Clean transmission fluid is supposed to be dark red or red translucent color. Transmission fluids are dyed to help in identification. The color will enable you to tell when the fluid is aging and when it needs replacement. When transmission fluid is new, can be yellow, and blue but the majority are red.

What level should your transmission fluid be at?

If the engine is cool, it should be at the upper end of the “COLD” mark. If the engine is hot, the level should be at the upper end of the “HOT” mark. If it's lower, you should add some amount of automatic transmission fluid.

When should I check my transmission fluid level?

Most mechanics recommend checking the transmission fluid when both hot and cold. This helps you to cross-check the levels of the fluid when both hot and cold. The reason why you should check when hot or cold is that the fluid expands when heated.

What does a slipping transmission feel like?

A slipping transmission tends to feel like your car is jerking or surging. You might even notice that the engine revs to a high RPM between gear changes. As you are driving, the transmission should be providing constant power to the wheels.

Why does my car jerk when changing gears?

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.

What does a dying transmission sound like?

If the sound resembles humming, buzzing, or clunking, you may be experiencing transmission failure. Bad automatic transmissions may emit humming, buzzing, or whining noises while manual transmissions have harsher “clunking” sounds.

Can low transmission fluid cause jerking?

Rough Shifting or Jerking Transmission

Causes of rough shifting include: Transmission Fluid Low or Poor Condition – Vehicles low on transmission fluid or that are operating with worn out or contaminated fluid are likely to experience hard shift conditions.

What are the signs of transmission problems?

Can I top off transmission fluid?

Topping up, draining and refilling automatic transmission fluid. Top up the fluid levels through the dipstick tube, using a small funnel. Add a little at a time and check the level frequently to avoid overfilling. Use a clean funnel and fill slowly.

Can you mix old and new transmission fluid?

This fluid starts to lose its standard properties and should be changed to keep the transmission parts and its performance at its peak. Mixing old and news fluids wont give you the ideal viscosity and the reduces the performance of the transmission system.

How many bottles of transmission fluid do I need?

Depending on the make of your car and several other factors, vehicles take an average of 4 to 17 US quarts (3.8 to 16 liters) of transmission fluid to fill. It is best to refer to the car's service manual for the specific amount of transmission fluid it needs.
