What You're Getting Wrong About Transmission Fluid Changes

Whether you’re a first-time vehicle owner or a seasoned driver, here are some misconceptions you might have about transmission fluid changes.

160,000 Kilometres Is The Maximum Interval For A Transmission Fluid Change.

The main thing drivers get wrong about transmission fluid changes is when to do them. If you look online for recommended transmission fluid change intervals, or even in your vehicle owner’s manual, you’ll likely see a range of 95,000 km–160,000 km (or roughly 60,000 miles–100,000 miles). Many drives automatically default to the higher end of this range. They may even think that 170,000, 180,000, or 190,000 km is close enough. It isn’t.

Let’s remember what transmission fluid does. It cools and cleans transmissions. Did you know most transmission problems involve overheating? Without effective, clean fluid, your transmission is liable to overheat. Furthermore, because transmission fluid collects particulate matter as it cycles through your transmission, it becomes adulterated over time. It eventually turns sludgy, and then it can do more damage than good. There’s no harm in getting your fluid changed every 95,000 km. At Mister Transmission, we don’t charge a lot to perform a fluid change, and this service could save you thousands going forward in unnecessary repairs.

Transmission Fluid Is Mostly Used In Automatic Transmissions.

The above figures are for automatic transmissions. Manual transmissions typically require more frequent fluid/oil changes. A common recommended interval is 45,000–95,000 km. Most cars on Canadian roads use automatic transmissions, so when Canadian drivers first purchase a manual transmission vehicle, they’re often surprised to learn they don’t need transmission fluid at all. They need something else.

Transmission fluid is technically called automatic transmission fluid, or ATF. Manual transmissions use transmission oil, hypoid gear oil, or motor oil. And, just to make things more confusing, some manual transmissions do use ATF. If you could use some clear instruction on what’s best for your manual transmission, you can come to Mister Transmission. Our technicians can recommend what oil or fluid is best for your transmission and perform the necessary fluid/oil changes.

You Maybe Should Be Using Synthetic Transmission Fluid.

Synthetic transmission fluid offers some advantages over traditional ATF. It has the same essential molecular structure, but it’s synthesized. The synthesization process removes some impurities, so this fluid is often more efficient and can go longer without being changed. The technicians at Mister Transmission can let you know if synthetic fluid might be better for your vehicle.

Excellent customer service from start to finish !!! Aki/Manager ,Jody/Service Advisor and Sal went the extra mile to get the transmission connector pipe from an out of town parts dealer as the local dealer was unable to deliver it on time as promised. They replaced the leaking pipe due to rust perforation and also proactively recommended replacing the other rusted transmission pipe above it for peace of mind. This is a common problem for some Toyota Highlanders and Matrix models.The time it took to do the job by lowering the sub-frame was accurate and professionally completed. I highly recommend this branch.

I had a noisy whining noise coming from the drivetrain of my truck and needed to find a shop to inspect it promptly. I quickly found out that there were not many places I could go to in my area. One place suggested Mr Transmission would be a good place to get it looked at. I drove in spoke with the manager, Chris Guziak who had his employees take it for a test drive and then into the shop for inspection afterwards.It was discovered that it was a front differential spline bearing. I had recently purchased the truck which had an active warranty still on it. Chris promptly made out a repair estimate and with some patient negotiations with the warranty company finalized the coverage of the repair costs. Then settled on a date to get the parts & have the truck repaired. After leaving the the truck first thing in the morning, Chris sent me a message at 1:45pm to tell me the repairs had been completed! I was very pleased overall with their expedient, professional service. 🙂
