Signs Your Transmission Fluid Is Bad And Needs Changing

Transmission fluid is an essential component of a vehicle’s transmission system, and it’s responsible for lubricating, cooling, and cleaning the gears and other internal parts. Over time, transmission fluid can become dirty, low, or contaminated, leading to severe problems with your transmission. It’s essential to be aware of the signs that indicate your transmission fluid needs changing. If you notice any of these symptoms, don’t hesitate to bring your vehicle to Marlow Automotive for a transmission fluid change and a thorough vehicle inspection in Plano, TX, and surrounding areas.

Here are some signs that your transmission fluid needs changing:

1. Dirty Transmission Fluid

Dirty transmission fluid is one of the most obvious signs that your transmission needs maintenance. Checking the quality of the fluid is an easy way to determine the condition of your transmission. If you have an automatic transmission, pull out the dipstick and check the consistency and level of the fluid. Wipe it off and re-dip it to get an accurate reading.

Suitable transmission fluid should be clear or have a pink tint. If the fluid appears dark red or brown, it means it’s old and dirty and needs to be replaced. Not only will this dirty fluid cause issues, but it can cause damage to your transmission. Look to see any visible particles, as this can also indicate that it’s time for a transmission fluid change. Don’t wait for transmission damage; schedule an appointment with Marlow Automotive, your go-to for transmission repair in Plano, TX.

2. Transmission whining noise

A whining noise from your transmission is a sign of a problem that needs to be addressed. The timing of the whine can indicate where the problem is located. If the whine occurs when your vehicle is in reverse, it is likely an issue with the transmission fluid line. If the pipe is clogged, the fluid cannot flow properly, and your transmission is at risk of severe damage. 

On the other hand, if the transmission whines when you are moving forward, it indicates a problem with the torque converter. It’s important to have your vehicle inspected by an expert to determine the cause of the whine and recommend the best course of action.

3. Gears slipping

When dirty transmission fluid impedes proper hydraulic power, gears may slip due to insufficient pressure to maintain engagement. Cleaning or replacing the fluid restores adequate fluid flow and pressure, resolving the issue.

Additionally, worn or damaged internal components, such as the clutch or gears, can also cause slipping gears. In these cases, it is crucial to have the transmission inspected by a qualified mechanic and repair or replace any worn or damaged parts as necessary. 

4. Can’t go into reverse gear

Dirty fluid may restrict the fluid flow, making it impossible for the car to engage the reverse gear. Among the potential solutions, replacing or flushing the dirty fluid can be a straightforward fix to the problem.

At Marlow Automotive, our team of certified mechanics performs thorough vehicle inspections in Plano, TX, to identify and address any potential issues that may prevent your car from moving in reverse. From dirty transmission fluid to worn-out internal components, we use the latest diagnostic tools to accurately diagnose the problem and provide effective solutions.

5. Engine running hot

A malfunctioning transmission can contribute to an overheating engine. When transmission fluid does not flow properly, it may not be able to enter the cooling tank and dissipate heat. Also, slipping gears, friction, and wear can lead to increased heat in the transmission, which can then transfer to the rest of the engine. If other potential causes of engine overheating have been ruled out and the issue persists, it may be worth checking the transmission fluid as well, as it may be the underlying cause.

6. Grinding noise

Grinding noises from the transmission can be caused by dirty transmission fluid, leading to issues similar to low fluid levels. If you hear these sounds, checking the fluid levels and their condition is essential. Even if the fluid levels appear sufficient, if the fluid is dirty, it may not effectively lubricate the transmission’s internal parts, resulting in unusual and undesirable noises. It’s important to address this as soon as possible, so it doesn’t cause further damage.
