What is a Transmission Oil Change?

When doing some online research about transmissions you might come across some terms and some ideas with which you are not familiar with. There are automatic transmissions and manual transmissions. Do you know the difference? There is transmission fluid and there is transmission oil? Are they different? Does transmission fluid need to be changed? Does transmission oil need to be changed? Well, don’t worry, this article will try to answer some of those questions.

Automatic vs. Manual Transmissions

A manual transmission requires more work from the driver. A manual transmission needs the driver to physically shift the vehicle into different gears, using a clutch pedal and shift knob. In order to move the vehicle forward and reach higher speeds, the driver must manually shift gears to get to the desired speed. An automatic transmission, on the other hand, does all the grunt work for you, changing gears fluidly as you push on the gas pedal.

Both automatic and manual transmissions have their pros and cons. Automatic transmissions are easier to use but manual transmissions give the driver more control of the vehicle. Vehicles with manual transmissions are more likely to be cheaper and there is some evidence to suggest that they are more fuel efficient. And the reason for going over automatic and manual transmissions will become clear soon.

Transmission Fluid

Transmission fluid allows the transmission to work. Transmission fluid works as a lubricant for the parts within your transmission. Transmission fluid is optimized for the functions of the transmission. These functions include valve operation, brake band friction, and the torque converter. Transmission fluid is required in all automatic transmissions.

Transmission Oil

While all automatic transmission require transmission fluid, this is not true for all manual transmissions. Some manual transmissions do use transmission fluid, but others use gear oil or sometimes engine oil. Sometimes gear oil is called transmission oil. The transmission oil lubricates the manual transmissions and other parts involved.

Transmission oil has a noticeable odour because of its sulfur-bearing anti-wear compounds. These compounds are necessary to reduce high sliding friction by the helical gear cut of the teeth. In a motorcycle in which the clutch is bathed in transmission oil, there is usually nothing separating the lower part of the engine from the transmission, so the same oil lubricates both the engine and transmission.

Transmission Oil Change

The transmission fluid in an automatic transmission will typically need to be changed out every now and then. The same is usually true for transmission oil in manual transmissions. However, speaking very generally, transmission oil changes are needed less frequently than transmission fluid changes. Some auto manufacturers claim that the oil never needs to be changed, as their transmission is a closed circuit. However, the oil might need changing due to other transmission problems, repairs, or leaks. These claims should be treated with a critical eye and you should ask a technician at a transmission shop if your specific vehicle might require a transmission oil change.

Frank Matchett - You fit our vehich

Frank Matchett - You fit our vehichle (Toyota Celica) into the Coquitlam Shop so quickly on Monday, June 29th. I am from Kamloops. This was during Canada Day week too. You found a transmission on Vancouver Island and even offered to pick it up yourself if possible. You personally dropped me off and picked me up at the location I was staying at on Port Moody. I so appreciated that kindness. You went above and beyond and kept me, reassured that I would be home on Thursday. My husband was not with me yet you communicated the updates with both him & myself (he was in Kamloops.) You were wonderful with your communication, swiftness in finding the part, I\'m grateful that you fit my car in during this holiday week & your kindness to drop me off & pick me up was so appreciated. So thankful for all that you did Frank Matchett. Sincerely - Mrs. K Devlin
