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.

I had an issue with my Nissan Altima jerking on the way home. Waited into I could take it here and have them do a quick test drive (which is free and very nice, though they may not feel the same issue which is the hard part). Peter was able to tell something was wrong and it’s a common issue with the CVT transmission on Nissans. He took us in the back of the shop as they were currently working on one and could show us the pulleys and CVT housing and the one piece that fails. Unfortunately, due to the price of the parts from Nissan, and low margins, and the fact that in order to fix the one small part would require a whole new transmission to ensure everything was new, it would be $4,500-5,500 + taxes. This is basically the value of the car (probably more than the worth) so not really an option for us. We appreciated the detailed info and seeing the parts and the free test drive. Very helpful - so if you have an issue with your transmission and know nothing about cars (like me), definitely worth it to take here.

William Ong
My son’s Pontiac Vibe was developing a whiny noise. We traced the sound to the front of the engine. We brought the car to Mister Transmission for them to diagnose. They took time to fully check it out and found the ac compressor to be the culprit. They didn’t charge us at all. I can’t thank them enough. They gave recommendation on what to do. Good people.

Akayla Mitchell
I don’t even know where to begin. Mark went above and beyond from our first conversation and walked me through everything and kept me updated the whole way. My car ended up being more complex then we all originally thought but the team handled it amazingly and Mark made sure I understood everything that was happening and worked longer hours to help trouble shoot. I must say have to worry about a big repair on a 3 month old car was not something I imagined having to navigate but Mark showed compassion and honesty I would go back in a heartbeat(hopefully I won’t need to for a long time!) Thank you again Mark, Tyler and team. My car runs 1000x better than when I bought it.
