Critical Transmission Maintenance Tips

How can you ensure your transmission is in good condition? Read our recommended best practices.

As it’s one of the most important components in your vehicle’s engine, ensuring your transmission is performing optimally is of the utmost importance. Transmissions have a myriad of moving parts that require maintenance to remain in good working order. Furthermore, it can be tricky performing proper maintenance on many of today’s modern transmissions that call for the equipment and experience of a certified technician.

The maintenance recommendations contained within your vehicle’s owner’s manual can assist you with knowing when you should have the transmission filter and fluid replaced. In general, most transmission experts recommend changing the fluid and filter every 40,000 km. Doing so may help you avoid a potential transmission breakdown.

Recommended Transmission Preservation Tactics

There are four simple things you should do to keep your car’s transmission running smoothly and efficiently, including:

  • Get your car’s cooling system serviced. Transmission failure typically occurs when the transmission overheats. One of the ways to prevent that from happening is to get your vehicle’s radiator and cooling system inspected. Your cooling system is responsible for cooling.
  • Replace the transmission filter. If applicable to your vehicle’s transmission, and according to your auto manufacturer’s recommendations, it’s worthwhile to have the transmission filter replaced by a professional technician intermittently.
  • Transmission fluid quality and level checks. Dirty, old transmission fluid, too little or too much fluid, can wreak havoc on your transmission. Some vehicle manufacturers have replaced the transmission dipstick with sealed units, making it impossible for the average driver to check the level and quality of the transmission fluid with ease. Regardless, many transmission problems typically stem from problems related to the transmission fluid quality and level.
  • Periodic inspection by a professional. The No. 1 way to ensure your transmission is in good working order is through periodic inspection and preventative maintenance performed by an experienced and certified technician.

It’s also useful to be mindful of the warning signs your transmission will send you. It helps to understand the basics of how automatic transmissions work.

Was very helpful getting my transmission fluid changed on a 280,000km car. Made sure the car was running right by doing a test drive before and after the appointment, and let me know of something else that needed fixing without pushing me to schedule another appointment so I wasn't running broken was tremendously nice!

Cory Spataro
The crew was super friendly. Even though I berated them with questions they were happy to answer them in detail and the customer service was excellent. It was a very expensive repair but I had a general idea of what the cost would be going in. It took a fairly longer time than they originally said but they were extremely thorough and I felt confident about the repair. However, a couple weeks later, a component sprang a leak and they honored their warranty and repaired everything and then some, free of charge.
