When Should I Change My Transmission Fluid?

Over time, transmission fluid deteriorates. It is necessary to replace the transmission on a regular basis in order to avoid damage to the transmission. The regularity with which you should replace your transmission fluid is determined by how often the transmission is utilized. If you mostly drive in the city, you are likely to stop and go often. This raises the transmission's working temperature, which implies the pressure on the transmission fluid is increased.

Other factors, such as pulling a trailer or carrying a big load in a vehicle with a high torque, can enhance this pressure. The transmission fluid will deteriorate faster as a result of this extensive usage. In general, a change is recommended every 90.000 kilometers, but this varies per vehicle, so always consult your owner's handbook to know what range is recommended.

How to tell whether it's time to replace your transmission fluid

You may look at a few things to see whether your transmission fluid is still in excellent shape:

  • The first step is to examine the color. A light red hue is common in transmission fluid. It will turn darker when the fluid becomes more burnt as it begins to deteriorate. This indicates that the fluid should be replaced.

  • Automatic drivers who experience gearbox slippage, loud shifting, or a loss of power engagement should get their fluid checked.

  • A transmission fluid that smells like gasoline is good. A foul or burnt smell indicates that the fluid needs to be replaced.

  • It should have a smooth consistency; if it contains debris or other particles, it should be replaced.

Draining old transmission fluid vs flushing it out

When you've concluded that your transmission fluid needs to be changed, you have two alternatives for doing so. The first is to get rid of the old fluid. This is accomplished by pumping in fresh fluid and pushing out the old. The benefit of flushing is that it removes all of the dirt and metal particles that have accumulated in the fluid. If the old transmission fluid is black and burned, however, drain it rather than flush it. That's because flushing might block the valve body with the scorched fluid.

The pan will be emptied and the filter changed if you wish to update your transmission fluid by draining. This approach will not eliminate all of the fluid since around half of it will remain in the system. To reduce the amount of leftovers in the system, certain mechanics drain and refill the system many times. Always refer to the owner's handbook to discover whether the manufacturer recommends draining or flushing.
