Low Transmission Fluid – Causes, Symptoms & Costs

Some signs of low transmission fluid

Chances are you’ve heard the saying “change your car’s oil every 3,000 miles or else.”

But what about transmission fluid?

Did you know it needs to be replaced too – and that means more than just checking the level?

In this post, we’ll break down everything you need to know about low transmission fluid, including the symptoms, causes, and costs.

So read on and get informed!

Low transmission fluid causes

One of the most common causes for transmission fluid to be low in trucks is simply a leak.

Over time, seals and gaskets can degrade, allowing transmission fluid to seep out.

In some cases, a small leak may not be detectable, but it can still result in a gradual loss of fluid.

If left unchecked, a leaking transmission can eventually lead to complete failure. Another common cause of low transmission fluid is improper maintenance. Transmission fluid should be checked regularly and topped off as needed.

However, many truck owners fail to do this, resulting in a gradual decline in fluid levels.

Finally, excessive heat can also cause transmission fluid to evaporate or break down, leading to reduced performance and eventually damage.

By familiarizing yourself with the factors that can cause low transmission fluid, you can help keep your truck’s transmission in top condition.

Signs of Low Transmission Fluid

There can be a few different symptoms that indicate your transmission fluid is low.

Some of the most common ones include:

1- Trouble Shifting Gears

One key symptom of no oil in the gearbox is gears slipping. If you notice that your truck is having trouble shifting gears, it could be a sign that the transmission fluid is low.

In addition, you may also experience slow gear engagement or a delay when shifting gears.

2- Overheating

Another symptom of no oil in the gearbox is overheating. If the transmission fluid is low, it will not be able to properly cool the transmission, resulting in excessive heat.

You may notice that the truck’s transmission temperature gauge is higher than normal or that the transmission fluid itself is overheated.

If you notice a burning smell coming from the transmission area, this could also indicate that there is not enough fluid – excessive heat can cause the fluid to break down, leading to a burning

3- Fluid Leaks

As we mentioned earlier, one of the most common causes of low transmission fluid is a leak.

If you notice any fluid leaks under your truck (on the garage floor or driveway), it’s important to have it checked out as soon as possible.

4- Strange Noises

If the transmission fluid is low, it can cause the gears to grind or make other strange noises.

If you notice any unusual sounds coming from the transmission, it’s important to have it checked out by a professional.

5- Check Engine Light

In some cases, a low transmission fluid level can trigger the check engine light.

If you notice that the check engine light is on, it’s important to have the truck diagnosed by a professional to determine the cause.

How to Fix Low Transmission Fluid Problem?

In most cases, the only way to properly fix low transmission fluid is to have the transmission system flushed and refilled.

This will remove any debris or contaminants that may be in the system and replenish the fluid level.

In some cases, a transmission repair or replacement may be necessary.

If you’re not sure what to do, it’s always best to consult with a professional. They will be able to diagnose the problem and recommend the best course of action.

How Much will a Transmission Fluid Flush and Fill Cost?

The capacity of your vehicle’s tank is usually between 5 and 15 quarts. You’ll also need a filter, as well as possibly a new pan gasket.

Based on the above, the cost of flushing out and filling your transmission fluid will vary depending on a number of factors, including the type of vehicle you drive and the type of transmission (manual or automatic).

In general, however, you can expect to pay between $100 and $250 for the service.

If you have an older car with a manual transmission, the job is going to be less expensive because it’s a simpler process.

On the other hand, if you have a newer car with an automatic transmission, it’s going to be more expensive because the job is more complex.

Some transmission shops may also charge a higher price if they have to flush your transmission as part of the service. This is an additional step that’s sometimes necessary to remove all of the old fluid from the system.

In most cases, it’s best to have your transmission fluid changed at a shop that specializes in transmission services.

This is because they have the knowledge and experience necessary to do the job correctly. They’ll also have the proper tools and equipment to properly flush the system, if necessary.

What Can Cause Transmission Problems After a Fluid Change?

When a car mechanic changes the transmission fluid, they are supposed to drain all the old fluid out and then fill it up with new, clean fluid.

However, sometimes transmission problems can occur after a fluid change.

The number one reason for this is usually due to contamination.

If the mechanic does not properly clean out the transmission pan and torque converter, small bits of debris, varnish deposits, and old fluid can be left behind.

These contaminants can then mix with the new fluid and cause clogging and other issues.

In addition, if the wrong type of fluid is used, it can also lead to transmission problems.

Therefore, it is important to make sure that the mechanic performs a thorough flush and uses the correct type of fluid in order to avoid transmission problems after a fluid change.

Final Thoughts

Transmission fluid is essential for lubricating the moving parts in your transmission and keeping it cool.

If the fluid levels go down or if the oil becomes contaminated, it will no longer be able to do its job properly.

This will lead to increased friction and heat, which can damage the transmission and cause it to fail.

Flushing out and refilling your transmission fluid is the best way to fix low transmission fluid levels.

However, this is a job best left to a professional. While you can save a few dollars by having the job done at a regular service station, it’s not worth the risk of having your transmission damaged.

Transmission repairs can be very expensive, so it’s best to play it safe and have the work done by an expert professional.
