When your transmission fluid is low, your car won't generate as much hydraulic pressure, leading to what's known as gear slippage. Gear slippage commonly manifests as a failure to accelerate properly. When your transmission fluid is low, you may notice your vehicle reaching high RPMs while moving sluggishly.
What are the symptoms of low transmission fluid?
Along with gear slippage, low transmission fluid levels can also cause low levels of pressure, which leads to slower engagement when shifting gears. If you notice your transmission takes a second to engage when put into drive or reverse, it could be due to low fluid levels.
Can I drive my car if transmission fluid is low?
Driving your car through a low transmission fluid level is dangerous to you and the vehicle. Failure to top up the fluid is a hazard that might cause extreme damage to the transmission, the engine, and essential components that keep the car running.
How does a car act when it needs transmission fluid?
Not being able to shift is a direct result of having low transmission fluid. Slipping Gears - On the flipside, slipping out of gear is another side effect of having low transmission fluid. For example, you may be maintaining your current speed, then suddenly feel your vehicle downshift or shift to a higher gear.
How long can you drive a car with low transmission fluid?
If you check your transmission fluid level and it's below low, then you're fine to drive for up to 10 miles as long as you drive slowly. But if the pedal is pressed all the way to the floor and there's no transmission fluid in your vehicle, then it's best not to drive at all until you get that checked out.

Can I just add more transmission fluid?
If the transmission has been drained, you will need 4-12 quarts of fluid to fill it back up. Follow the vehicle service manual for the recommended type and amount of fluid to use. If the fluid is very low when it is checked, then add more fluid and look closely for any leaks.

There will be a fill plug on the side of the transmission case. This is not the drain plug located at the bottom of the sump.
What happens if you mix old transmission fluid with new?
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.
Can 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.

Will check engine light come on for transmission fluid?
Your transmission fluid plays an important role in keeping the parts of the system lubricated. If the parts of the transmission are not properly lubricated, extreme friction can occur, which could result in damage. As a result, the check engine light can be triggered. Check the fluid levels and add some, if needed.
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 is my car dragging when I accelerate?
Dirty fuel injectors are among the most common reasons for why an accelerator becomes jerky. The dirty injector leads to your car losing power when you attempt to accelerate while at a stop and when you try to drive at a consistent speed. This is the result of an engine misfire.
Can changing transmission fluid cause problems?
That's not really true, but here's what IS true. If the valve body gets all gunked up with transmission fluid that's damaged, the driver could lose the ability to shift between gears. And that's why so many people believe that changing old transmission fluid can cause it to slip.
Will changing transmission fluid help shifting?
Though changing transmission fluid can't fix mechanical problems, it does make for smoother shifts and can extend the life of your transmission. And even when manufacturers recommend fluid change intervals of 150,000 miles under normal conditions, it may be a good idea to change it more frequently.
Can I just add transmission fluid instead of changing it?
There are many fluids that run throughout your vehicle, but one of the most important to keep track of is the transmission fluid. Whether or not you should change it is not a matter of debate: Yes, you should.
What does Brown transmission fluid mean?
Brown and dark brown hues indicate that the transmission fluid is no longer viscous and it is oxidizing. Oxidizing means the fluid is filling with air bubbles and is unable to do its job. Change your transmission fluid right away when it's this color.
What happens if you drive with dirty transmission fluid?
Excess dirt and contaminants in the transmission can cause a loss of hydraulic power, therefore keeping the transmission from staying in the appropriate gear. A dirty transmission can quickly start to interfere with transmission fluid flow, resulting in the lack of pressure needed for the transmission to stay in gear.
