4 Transmission Oil Change Mistakes To Avoid

4 Transmission Oil Change Mistakes to Avoid

When conducting a transmission oil change, it’s important to get it right, but everybody makes mistakes, so here are four common errors to avoid.

Mistake #1: Confusing Transmission Oil For Transmission Fluid

The first mistake concerns nomenclature. Transmission fluid typically refers to automatic transmission fluid, or ATF. Automatic transmissions use ATF. And, somewhat confusingly, some manual transmissions also use ATF.

However, other manual transmissions use a type of oil. This could be regular engine or motor oil, hypoid gear oil, or transmission oil. Assuming your vehicle still has its original transmission, your owner’s manual should dictate which type of oil is best for your manual transmission. If you’re not sure, bring your vehicle into Mister Transmission and we can inspect your transmission and let you know.

Mistake #2: Waiting Too Long Between Transmission Oil Changes

Whatever type of fluid or oil your transmission needs, it performs the same basic function, which is similar to the function of motor oil in gasoline-powered internal combustion engines. Transmission oil lubricates and cools the transmission. Without enough oil, it’s easy for the transmission to overheat. This can cause lasting—and expensive—damage.

Most vehicles in Canada use automatic transmissions, so if you’re new to manual transmissions, you’re not alone. One mistake drivers of manual transmission vehicles often make is assuming that the fluid change interval is the same; it isn’t. The recommended change interval for manual transmissions is typically a bit shorter for manual transmissions, about every 48,000–80,000 km. Again, your owner’s manual should have a more specific recommendation.

Mistake #3: Not Checking The Quality Of The Transmission Oil When You Do Change It.

Whether it’s transmission fluid or oil, many people tend to focus on quantity over quality. They assume it’s a matter of fluid levels and if the level is below the recommended line, they top it up. And that’s great, but what about the quality of the oil? If it smells burnt or looks discoloured, there could be something wrong with your transmission. If you think there’s something wrong with your transmission oil, bring your vehicle into Mister Transmission and we can check it out.

Mistake #4: Not Knowing What The Heck You’re Doing

At this point you might be thinking, “OK, but how do I check my transmission oil?”. That’s a fair question, but the answer depends on your model of transmission. Come to Mister Transmission for any of your transmission needs.

Victor S
To fix the tranny of my old car was expected of him because he is running the same Mister Transmission place for decades. But what wasn’t expected of him to tune my 40 yr old car to perfection, and fix my leaky carburetor. Changing the upper arms and wheel bearings were also extra. So if you look for something more than just your transmission, I doubt you can find a better mechanic than Kenny at Mister Transmission on Woodbine at Dennison. You’ll be seriously satisfied, and more than pleasantly impressed!

I had an issue with my subaru, and was given limited options in stratford to fix it. I took it to Gary and his team, and not only did he give me options for repair, he was very straightforward and thorough with his explanation on the problem and the best way to solve it. I would highly recommend anyone with transmission issues to take it here, even if only for a second opinion
