What Will Happen If I Drive With A Very Low Transmission Fluid?

by Uneeb Khan

You and your car are both at risk if your gearbox fluid leaks continuously. Low transmission fluid causes excessive wear and tear, which eventually leads to transmission failure because the car transmission runs hot. Bring your automobile auto transmission specialist at your local location as soon as you suspect a leak in the transmission fluid before it becomes a costly repair.

Let’s First Understand What Is Transmission Fluid?

Transmission fluid helps in lubricating the parts of a car’s transmission to ensure optimal functioning. Since oil changes are a common component of vehicle maintenance, engine oil is a topic that most people are familiar with. Even though it’s less well-known, transmission fluid is crucial. All the components in your gearbox, or the transmission in your car, are kept from grinding as they move by transmission fluid. When deciding which transmission fluid is appropriate for your car, it is advisable to read the recommendations of your owner’s manual or you can search “mechanic near me” and find a reliable car mechanic.

What Happens If I Drive With A Very Low Transmission Fluid?

A transmission oil leak causes you to lose transmission fluid and if you keep driving with low fluid levels, you could permanently harm your car’s transmission, necessitating expensive rebuilds, transmission replacement, or repairs depending on the extent of the damage. Therefore checking transmission fluid regularly is important for all car owners. But how to know whether the transmission fluid is low or not?

Symptoms Of Low Transmission Fluid

1. Noises

You shouldn’t hear any noise when driving if your transmission is functioning properly, and the gears should shift smoothly. Unusual noises vary not only between brands and models but also according to the kind of car transmission. When you transfer gears, manual transmissions frequently make a loud clunking or grinding noise, whereas an automatic transmission sounds whiny or buzzing.

Even if noises can suggest that the fluid level is growing low, you probably won’t be able to identify the issue on your own. To avoid time-consuming repairs, it is advised to have the problem quickly evaluated by a qualified transmission mechanic. Getting a car diagnostic test will help you finding the problem more efficiently.

2. Transmission Oil Leak

As was previously stated, the fluid inside the transmission housing of your car serves as both the only source of lubrication and a cleaning and conditioning agent for the surrounding transmission seals. If you see a red fluid underneath your car, it’s almost probably losing transmission fluid because leaks are a typical source of transmission issues.

We advise getting in touch with your auto transmission specialist to arrange an inspection of the faulty transmission. A failing gasket or hose could be simply swapped out for repair. However, a transmission oil leak will only become worse if left unattended as the fluid level decreases.

3. Slipping Gears

A grinding sound can be produced when gears miss, which is caused by low fluid levels. The rare slipped gear may appear to be a minor problem at first, but it’s always a good idea to have the transmission checked out to prevent further expensive repairs.

4. Burning Smell

You should find the “transmission service near me” if your car is emitting a bad odor. Your automobile may start to smell like burnt rubber for a number of reasons, one of which is the possibility of overheated transmission fluid. This symptom might be a sign of low fluid levels.

Too much heat in a transmission increases friction between parts, which inevitably leads to muck buildup and transmission corrosion. If this state is continued, the transmission will eventually sustain enough damage to stop working.

5. Warning Lights

Your dashboard will display a warning light if the temperature of your transmission fluid is higher than usual.

What If You Completely Ran Out Of Transmission Fluid

It’s likely that your car won’t start at all if you totally run out of transmission fluid, especially if it has an automatic transmission.

In an automatic transmission car, one of the duties of transmission fluid is to establish a coupling between the engine’s output and your transmission; without fluid, there would be no coupling and the car would be immobile.

If you do let your transmission fluid totally run out, you will probably need to replace your transmission entirely because the metal gears inside will need to be repaired or replaced entirely and you very well know how expensive it is to bear complete transmission replacement cost.


For the sake of the health of your car, you should maintain the transmission system and find a car service near me and get the car inspection services regularly. It is crucial to the movement of the vehicle. In order to move your vehicle, hundreds of components must cooperate. You will eventually become stranded in the middle of the road if you neglect to maintain the transmission.
