What is Automatic Gear Oil Change?

Auto transmissions use gear oil to transmit power from the engine to the gears. This transmission fluid is also responsible for lubricating the gears and preventing them from coming loose, which can cause damage and lessen the car’s performance. It is important to change your gear oil every 3,000 miles or every three months, whichever comes first.

When it comes to your Toyota car, the oil that keeps everything moving is just as important as the engine. The gearbox uses a finely meshed planetary gear train to turn the engine, and it can become damaged over time if not given the proper protection.

That’s why it’s important to change your automatic gear oil every 3,000 miles in Toyota cars. This will keep the gears running smoothly and prevent any damage from happening. If you do have to take your car in for service, make sure to bring along your gearbox oil filter with you so they can verify that you’ve been following this schedule.

How to Check the Oil Level in a Gearbox?

To assess the health of your gearbox oil, check its colour. New oils are brightly coloured, often red, and semi-transparent. As they degrade or gather deposits, they become darker, lose their transparency, and may have a burnt smell due to oxidation.

Follow these steps to check your gearbox oil:

  • Open the bonnet and find the transmission dipstick, which should be indicated in your owner’s manual. If your vehicle doesn’t have one, you may need to use a jack or lift to raise it and carefully remove the transmission fill cap from the assembly.
  • Pull the dipstick out of the filler tube. If you’ve lifted your vehicle, use a ruler, screwdriver, or other tool to sample the oil.
  • Check the oil’s colour. If it’s dark brown, black, or light pink (often due to water contamination), you should change it. Red-brown, semi-transparent fluid is somewhat degraded but doesn’t necessarily mean it needs changing.

How to Exchange the Gear Oil?

If you’re not experienced in vehicle or machinery maintenance, it’s best to get a professional to change your gear oil. However, if you want to do it yourself, follow these steps:

  • If your vehicle or machinery has a drain hole, place a catch pan beneath it. Otherwise, place a catch pan under the entire gearbox assembly.
  • Unscrew the drain bolt or remove the gearbox pan and allow all the fluid to drain into the catch pan.
  • Take out the old gasket and filter, and have replacement components ready.
  • Inspect the gearbox pan and clean the magnet of any small metal pieces. If large fragments are present, your gears may be severely worn and need replacing.
  • Install the new gasket and filter, then bolt the pan back onto the machinery or vehicle.
  • Use the Total Lubricants Catalogue to get the correct gear oil for your vehicle or machinery, after checking your owner’s manual for the type of fluid required. Alternatively, use the Lub Advisor tool and select your vehicle, click the blue ‘Select other component’ button, then choose the correct button for your type of gear assembly.
  • Check your owner’s manual for how much fluid your gearbox requires.
  • Use an oil pump or measure the correct amount and pour it into your gearbox.
  • Allow the oil to settle for a few minutes, then start the engine and run the vehicle for a short period.
  • Check the oil level to make sure it’s correct (refer to the previous section of this article for instructions).
  • Dispose of the used oil responsibly.

The Difference Between Transmission Fluid in an Automatic Versus a Manual Transmission

In an automatic transmission, the fluid acts as a hydraulic fluid that assists in gear changes. It also helps to cool and lubricate the transmission components, including the gears, clutches and bands. Automatic transmission fluid also contains friction modifiers, which are additives that help to reduce wear and tear on the transmission components.

In a manual transmission, the fluid primarily acts as a lubricant for the gears and bearings. It also helps to cool the transmission and prolong its lifespan. Manual transmission fluid does not contain friction modifiers, as the gears and synchronizers require a certain amount of friction to operate correctly.

It’s important to note that the type of fluid required for each transmission can vary depending on the make and model of the car. It’s essential to consult the car’s owner’s manual or a trusted mechanic to ensure that you’re using the correct type of transmission fluid for your vehicle. Using the wrong fluid can lead to significant transmission damage and potentially costly repairs.
