What is Transmission Oil and Do You Need to Change It?

You’ve probably heard of a transmission fluid change, and you’ve probably heard of an engine oil change, but what exactly is a transmission oil change?

Automatic Transmission Fluid, Motor Oil, Transmission Oil, And More

There are a number of different fluids in modern automobiles, and many of them need to be changed, topped up, and flushed out periodically. There’s hydraulic steering fluid, brake fluid, windshield wiper fluid, and more. When we talk about auto oil, we’re usually referring to engine oil, also known as motor oil. This oil lubricates an internal combustion engine and is critical to its operation. Your transmission requires a fluid that serves a similar function.

Automatic Transmission Fluid Vs. Manual Transmission Oil

A strong majority of Canadians drive an automatic transmission vehicle. An automatic transmission shifts gears automatically for the driver whereas a manual transmission requires the driver to use a clutch pedal and gear shifter to shift gears to achieve higher speeds. Automatic transmissions use automatic transmission fluid which lubricates and cools the transmission.

Some manual transmissions also use automatic transmission fluid. Other manual transmissions use heavyweight hypoid gear oil and some just use regular motor oil. For manual transmissions that use transmission oil, there is an obvious question: does transmission oil need to be changed much like automatic transmission fluid does?

Are Transmission Oil Changes Necessary?

Yes, transmission oil needs to be changed periodically. Just like automatic transmission fluid, manual transmission oil has to be changed so that your transmission receives the lubrication it needs to operate properly. If you’re driving with the transmission that your vehicle came with, then your vehicle owner’s manual should indicate how often you ought to change your transmission oil.

Speaking very broadly, manual transmission oil needs to be changed on a slightly more frequent schedule than automatic transmission fluid. The usual recommended interval for a manual transmission oil change is about every 50,000-95,000 kilometres. That’s clearly a very wide range. Where your transmission falls within that range depends on a number of factors including the age of your transmission and how you use your vehicle. For example, whether you do more city driving or country driving affects your transmission oil change interval, as well as if you use your vehicle for work-related tasks, such as towing.

Pankaj Parwale
Honest, helpful, and highly recommended! Aki checked my car for a check engine light and accurately diagnosed a transmission issue. Instead of pushing for an expensive full transmission replacement, he checked the transmission pan and suggested starting with a fluid flush since it was already due. His honest approach worked perfectly, and my car has been running great with no issues since. I recommend checking with them for any transmission issues.

Brought in my 18 Silverado with the well known 8 speed transmission problems, mark gave me a call and suggested a trans rebuild, he gave me the full run down from top to bottom on what was wrong and needed replacing and i gave them the go ahead, I didn’t realize how bad I had it until I got the truck back and it drove like new! as someone who works on their own vehicles, I’m picky when it comes to anyone else working on it, the guys at Mr transmission st Thomas were an easy decision, by far one of the easiest shop I’ve had to deal with for any type of service, mark was fair friendly and taught me a thing or two, if you have any transmission needs, these are your go to guys without a doubt
