What Is a Toyota Automatic Transmission?

Toyota vehicles with automatic transmissions are more common in Canada than those with manual transmissions. Automatic transmissions use sensors to determine when they should shift gears, changing them by using internal oil pressure. An automatic transmission temporarily disconnects itself from the engine when shifting gears, which is controlled by the lock-up in the torque converter, which transfers power from the engine to the transmission via fluid coupling. An automatic transmission reaches different speeds by creating different gear ratios.

What are the common problems in a Toyota automatic transmission?

Toyota is known for making dependable and durable vehicles. Even so, transmissions are complex and there’s a lot that can go wrong with them. Arguably, Toyota transmissions are the most problematic parts of their vehicles.

There are many registered complaints about Toyota transmissions not accelerating or getting stuck in gear. Other complaints include rough and delayed shifting and sudden losses of problems. These problems are annoying at best and dangerous at worst. That’s why it’s imperative to bring your Toyota to Mister Transmission of Markham for inspection as soon as you notice any of these issues, or if your check engine light turns on for no apparent reason.

How we diagnose transmission problems

The first step in diagnosing a transmission is listening to what the vehicle’s owner says. There are some telltale signs of certain transmission problems, and learning about what you’ve been experiencing can help us decide where to look. Some common signs of Toyota automatic transmission problems include:

  • Transmission shuddering
  • Difficulty accelerating after a stop
  • Rough shifting
  • Delayed shifting
  • Sudden shifting

Modern Toyota vehicles have onboard computers that help the transmission run more efficiently. The downside is that these computers make transmission repair more complicated. Thankfully, we at Mister Transmission of Markham have cutting-edge diagnostic technology that allows us to communicate with your Toyota’s onboard computer.

To determine your transmission’s problem, we first connect your Toyota’s onboard computer to our diagnostic equipment. This creates a code that tells us where the problem is. After an inspection and possible adjustment, we can conduct a test drive. This allows us to test how your transmission handles in real-world conditions. Following this, we may decide that a lift inspection or pan examination are necessary.

Navalan Prabaharan
I had a great experience at this location. Roma was wonderful to talk to and he was very transparent about my options about clutch work for my car. They were very accommodating with my questions and took the time to give me updates about part and labor timing/costs. Everyone I interacted with was kind and courteous, and in the end my car came back feeling brand new! Would definitely recommend to others and should I have another issue, I would bring my business back here.
