Can Changing Transmission Fluid be Bad?

You might wonder if changing the transmission fluid can be done safely. The short answer is yes. It can be helpful to change the transmission fluid in certain circumstances. However, it can also prove harmful. 

We will cover a few points here. First, let’s look at why changing transmission oil is so important.

Why is it important to change transmission fluid?

Transmission fluid is crucial for proper lubrication. Transmission fluid can become contaminated with dirt and grime, which can lead to fluid flow problems in the moving parts. Old or contaminated transmission fluid can make it difficult to flow and cause heating problems, whining, and slippage. Since transmission fluids do not evaporate You have to replace them if they become dry or stale like engine oil.

It is recommended that transmission fluid be changed every 50,000 to 100,000 mi. If it has clogged up, The transmission fluid should be changed only if it is done properly. Let’s look at the situations where changing the transmission fluid could cause damage.

When is it okay to not change transmission fluid?

It is important to ask yourself several questions before you make a decision about whether changing the transmission fluid is good or bad for your vehicle.

• Is your car old or new?
• How well is your transmission maintained?
• Do you have an automatic transmission or a manual transmission in your car?
• Are you a low- or high-mileage driver?

Based on the questions above, you can decide whether your transmission fluid needs to change. There are two options: flush the old fluid and change the transmission fluid.

When is the transmission fluid due for replacement?

This will depend on how well your car’s transmission has been maintained. The old transmission fluid can still mix with the new fluid even after it has been changed. After changing the fluid, 50% of the old fluid remains. However, flushing will remove 100% of the old fluid.

If the gearbox, or any other transmission component isn’t maintained well, grease and grime can build-up in the fluid. If this happens, it is possible for the fluid to remain in the transmission system’s tubes. If the vehicle is new, or the transmission system isn’t well-maintained, it is better to change the fluid than flushing.

When is transmission fluid to be changed?
