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.

Norm Buda
I broke down just outside Richmond Hill 3 days before Christmas and dropped off my broken vehicle with Gary. I was on a spiritual journey across Canada and that was where things got put on hold. Slow down is the message.Long story short folks, Gary and his men gave it back to me first week of January and I immediately headed back to Alberta. I drove 4km on a rebuilt transmission, transfer case and universal joint replacement. I drove through some of the worst conditions I have ever done before and all the time didn't even have a single worry or thought about the work that was just done cause I just knew they were professionals and I was at peace. Thanks again Gary for your help. God bless you guys! Have a prosperous 2022.

Colin Puchala
Driving through Toronto from out of town we had transmission problems with our van. Ray at Mister Transmission was an absolute star!! After calling several places, I talked to Ray and he was very welcoming and said to bring it over and he would take a look. From the very beginning, I totally trusted his advice and he was accomodating considering our situation. He gave us the straight facts and information that we needed and truly helped us out. Too bad that we are not from the area as he would definitely be someone that I would trust with my vehicles and who would become our "go to" guy. Thanks Ray so much for your help!
