1. Discolouration

Ordinarily, healthy transmission fluid is typically red or pink for automatic transmissions and light brown for manual transmissions. So, if you notice that your car transmission fluid becomes darker or brownish, that could indicate contamination or degradation of the fluid. Therefore, you have to change it before it affects other parts of your car, causing more havoc.

2. Burnt Odor

Transmission fluid should have a slightly sweet or oily smell. If you detect a burnt odour, similar to burnt toast or overheated machinery, it suggests that the fluid has overheated and degraded, potentially due to friction or overheating within the transmission system. This is a sign you can’t ignore to avoid further damage.

3. Fluid Leaks

If you notice visible leaks or puddles of transmission fluid under your vehicle, these are clear indicators of a problem. Leaks can occur due to damaged seals, gaskets, or transmission cooler lines, leading to low fluid levels and potential transmission damage. Your next line of action is to check if the transfusion fluid is degraded or still okay. You can’t afford to overlook a fluid leak in your car.

4. Slipping Gears

A slipping transmission occurs when the vehicle unexpectedly changes gears or experiences a loss of power during acceleration. Degraded transmission fluid can cause insufficient hydraulic pressure, resulting in slipping gears and reduced performance. Take note!

5. Rough Shifting

Rough or jerky shifting between gears is another common sign of degraded transmission fluid. The fluid’s diminished lubricating and hydraulic properties can lead to harsh gear transitions and hesitation during shifts.

6. Transmission Noise

Unusual noises such as whining, grinding, or clunking coming from the transmission area can indicate internal damage or insufficient lubrication due to degraded fluid. These noises may become more pronounced as the condition of the fluid worsens.

7. Delayed Engagement

Delayed engagement occurs when there is a delay or hesitation in the transmission engaging after shifting into gear. Degraded fluid can impede proper hydraulic function, causing delays in gear engagement and potentially leading to transmission damage.

If you notice any of these signs of degraded transmission fluid, it’s essential to address the issue promptly to prevent further damage to your vehicle’s transmission system. You need to do regular fluid checks and replacements, as manufacturers recommend, to help maintain optimal transmission performance and prolong the lifespan of your transmission.

How long does automatic transmission fluid last?

Now, let’s talk about the automatic transmission, how long can transmission fluid last in automatic cars, and how often it can be changed.

The lifespan of automatic transmission fluid (ATF) can vary depending on several factors, including driving habits, operating conditions, and vehicle manufacturer recommendations. Generally, ATF should be replaced every 30,000 to 100,000 miles or every 2 to 7 years. However, it’s essential to refer to the vehicle’s owner’s manual for specific guidelines tailored to the make and model.

Some modern vehicles may come equipped with lifetime ATF that is designed to last the lifetime of the transmission. However, it’s important to note that even lifetime ATF can degrade over time due to factors such as heat, contamination, and wear and tear on transmission components.
