Why Does Transmission Fluid Need To Be Changed?

Transmission fluid needs to be changed periodically for several important reasons:

  1. Lubrication: Transmission fluid lubricates the moving parts within the transmission system, reducing friction and preventing excessive wear and tear.
  2. Heat Dissipation: The fluid helps to dissipate heat generated during operation, preventing the transmission from overheating and potential damage.
  3. Contaminant Removal: Over time, transmission fluid can accumulate contaminants such as dirt, debris, and metal particles. Changing the fluid removes these contaminants, ensuring smooth operation and preventing clogs or blockages.
  4. Fluid Condition: Transmission fluid can break down over time, losing its effectiveness and becoming less capable of performing its essential functions. Regular fluid changes help maintain the fluid’s quality, ensuring optimal performance.

Changing the transmission fluid at recommended intervals can prevent friction, overheating, and potential damage to the transmission system.

Adhering to the manufacturer’s guidelines is crucial to maintaining the longevity and efficiency of your vehicle’s transmission.

What Are Some Signs That My Transmission Fluid Needs To Be Changed?

Why Does Transmission Fluid Need To Be Changed?

Recognizing the signs that your transmission fluid needs to be changed is crucial for maintaining the health and performance of your vehicle’s transmission system.

Here are some additional details about the signs indicating a need for transmission fluid change:

1. Discolored Fluid

Burnt Transmission Fluid

Transmission fluid should typically have a reddish or pinkish color. If you notice that the fluid appears dark, brown, or black, it is likely contaminated with dirt, debris, or worn-out particles.

Suppose the transmission fluid appears significantly darker than its original color. In that case, it strongly indicates that it has become oxidized and dirty.

This dark fluid often suggests the presence of sludge, which can impede proper lubrication and cooling within the transmission system.

In addition to a change in color, transmission fluid with a burnt smell clearly indicates that it has been subjected to excessive heat and may be ineffective in providing optimal lubrication.

The burnt odour can be caused by overheating, friction, or the breakdown of additives in the fluid.

As it ages, contaminants such as metal shavings, clutch material, and dirt can accumulate in the transmission fluid.

These contaminants can cause increased friction and wear on transmission components, potentially leading to more severe issues if not addressed promptly.

Monitoring the color and condition of your transmission fluid is crucial because clean and adequately functioning fluid is essential for smooth gear shifts, lubrication of moving parts, heat dissipation, and overall transmission performance.

2. Slipping Gears

Transmission Fluid Slipping Gear

Slipping gears, characterized by a sudden loss of power or delayed response when shifting, can indicate the need for a transmission fluid change.

Contaminated or insufficient fluid can cause inadequate hydraulic pressure, leading to gear slipping.

Changing the fluid restores pressure improves lubrication, and prevents further transmission damage.

If experiencing slipping gears, it’s important to check and change the fluid as needed and consult a professional for a proper diagnosis.

3. Rough Shifting

Transmission Rough Shifting

Rough shifting refers to a noticeable jerkiness or harshness during gear changes in an automatic transmission.

It can occur when the transmission fluid is old, degraded, or contaminated.

When the fluid loses effectiveness, it can result in insufficient lubrication and compromised hydraulic pressure, leading to rough shifting.

Any debris or contaminants can be removed by changing the transmission fluid, ensuring smoother gear transitions and improved overall performance.

If you experience rough shifting, it’s advisable to have the transmission fluid checked and changed to maintain the health and longevity of your transmission.

Consulting a professional can help identify and address any underlying issues contributing to the rough shifting.

4. Transmission Overheating
