Frequently asked questions on automatic transmission fluid change

Automatic transmission fluid should be changed every 30,000 to 60,000 miles. However, always check your vehicle’s manual for the manufacturer’s recommendation. Your driving habits and the conditions you drive in will affect how quickly your fluid degrades. Regular checks and following the manufacturer’s guidelines will help to make sure your transmission stays in good condition.

Some people believe that changing old transmission fluid can cause issues, especially in high-mileage vehicles. This myth stems from the fact that when automatic transmission fluid is changed, the new fluid can sometimes dislodge debris, causing problems. However, this is usually due to debris build-up.

If you don’t change the automatic transmission fluid, it can become contaminated and lose its effectiveness, leading to transmission wear and potential failure. Over time, dirty automatic transmission fluid can cause increased friction, overheating, and significant transmission damage. Regular changes will help you avoid costly repairs and keep the transmission running smoothly.

Fresh automatic transmission fluid is bright red and clear. If your fluid looks clean and smells fresh, it’s been changed recently. You can also check the service records for confirmation. If in doubt, ask your mechanic to check.

Signs that you might need a transmission flush include:

  • Slipping gears: The transmission struggles to stay in gear.
  • Delayed gear engagement: There’s a noticeable delay when shifting gears.
  • Overheating: The transmission becomes excessively hot.
  • Unusual noises: Grinding or whining sounds from the transmission.
  • Dirty fluid: The automatic transmission fluid is dark or discoloured.

A flush can help remove contaminants and restore the fluid’s effectiveness.

It’s often best to have a professional do it. The process can be messy and requires proper disposal of old fluid. Professional services also include checks and diagnostics to ensure everything is working.

Transmission fluid is used in automatic transmissions, while gearbox oil is used in manual transmissions. They’re made to do different jobs, so they’re not interchangeable. Automatic transmission fluid is designed for the hydraulic and cooling needs of automatic transmissions, while gearbox oil provides the necessary lubrication for manual transmissions.

An automatic transmission flush is a service where all the old automatic transmission fluid is removed, and new fluid is added. It helps remove contaminants and old fluid that might be stuck in the transmission. It’s more thorough than a simple fluid change and can help restore the transmission’s performance.

Yes, changing the automatic transmission fluid is necessary to keep your vehicle’s transmission running well. Over time, the fluid degrades and becomes less effective, leading to potential transmission problems. Regular changes help the transmission run smoothly and can prevent costly repairs down the line.

To extend the life of your automatic transmission fluid:

  • Regular maintenance: Follow the manufacturer’s guidelines for fluid changes.
  • Avoid excessive heat: Don’t overload your vehicle or tow heavy loads when you don’t have to.
  • Check for leaks: Regularly inspect your vehicle for fluid leaks.
  • Smooth driving: Avoid aggressive driving habits that can overheat the transmission.

Proper care and regular upkeep can significantly extend the life of your automatic transmission fluid and transmission.

An automatic transmission fluid change will typically take about 1 to 2 hours, depending on the vehicle and the service provider. This includes draining the old fluid, replacing the filter (if necessary), and refilling with new fluid. If more services or diagnostics are needed, it could take longer.

If your transmission fluid is low:

  • Check for leaks: Look for any visible leaks under the car.
  • Top up the fluid: Use the right type of fluid for your vehicle.
  • Monitor the fluid level: Regularly check the fluid level to make sure it stays within the recommended range.
  • Consult a mechanic: If the fluid level continues to drop speak to a mechanic so that they can inspect and fix any issues.
