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.

Aki and his staff worked very hard to find the source of my troubles and to find parts to repair, rather than change the transmission. They saved me a lot of money. Such courtesy, respect and honesty are hard to find. I will be confident in recommending this shop to all my friends and family.

This place, the owner, the everyone.. All of them absolutely amazing! From the free diagnostic to the surprisingly painless cost of fixing my car.. They are a wonderful, incredibly skilled, and most of all a caring crew. Go there for sure to get anything done for your car. I can't say enough nice things about them. They're so good that I am switching from my mechanic of more than five years and taking my car here for all of its service from now on. When you go here too, you sure as heck won't be let down or disappointed.
