What Is a Transmission Flush and Do You Need One?

By Mister Transmission

Maximizing the life of your vehicle’s transmission depends on regular maintenance including getting a transmission flush every three years

Among the myriad of moving parts and components that comprise your vehicle’s engine, the transmission is one of the most important, and it could be one of the costliest to repair or replace in the event of a complete breakdown.

The key to ensuring your transmission is in good working order is a matter of regular maintenance which includes getting a transmission flush every three years or as per the information in your owner’s manual.

What is a transmission flush?

Simply put, it’s a process by which transmission fluid is drained, followed by a process of removing all the grit, grime, and sludge that has been building up inside your transmission. Once completed, your old transmission filter is replaced (if accessible), and new transmission fluid is pumped back into your transmission all while adhering to the specifications of the manufacturer.

How to Tell If You Need a Transmission Flush

There are typically a few telltale signs if the automatic transmission in your car, truck, or SUV requires a transmission flush, including:

  • Your transmission fluid is a dark smoky colour and has a burned odour
  • You notice a leak
  • Your vehicle surges or stalls temporarily after being put into gear
  • The gears are slipping
  • You’re having problems changing gears
  • Your transmission is making strange noises

Remember: a transmission flush is a preventative maintenance procedure, not a cure-all for larger problems if your transmission or any of its moving parts are wearing down.
