Transmission Flush and Fluid Replacement – Getting in Gear with Car Maintenance
Transmission FlushTransmission service is the topic of this post in our Getting in Gear with Car Maintenance series. Part of your recommended regular vehicle maintenance, transmission service includes a transmission flush and transmission fluid change. Regular transmission services will keep your car performing at its best, and keep it running dependably.

What a transmission flush does for your vehicle
Transmission fluid is an essential lubricant that cools and protects the moving components in your vehicle’s transmission, and facilitates gear shifts. Like other automotive fluids, transmission fluid degrades over time. Transmission fluid deterioration can be accelerated by certain types of driving, such as city driving or heavy hauling. A transmission flush service gets rid of the old transmission fluid so it can be replaced with new fluid.

What happens during a transmission flush and fluid replacement?
Your auto service professional will:

  • Remove and inspect the pan
  • Replace or clean the screen or filter
  • Clean and reinstall the pan with a new pan gasket
  • Remove the old transmission fluid and replace it with fresh fluid

Why are transmission flushes important to your vehicle?
A transmission flush gets rid of old fluid and washes away tiny particles, such as clutch material and metal shavings, which accumulate as the fluid ages. Without a flush, those particles eventually clog passages and wedge between moving parts, causing wear within the transmission. Flushing the fluid gets rid of those particles and prevents the wear they cause. Regular transmission service allows your transmission to function better for years longer, which means you’re less likely to breakdown and be faced with a major transmission repair.

How often is a transmission flush needed?
Transmission service is typically recommended every 50,000 miles. As with all auto services, it is important to refer to your owner’s manual to see the recommendations for your specific vehicle.
