The transmission control module is an extremely important part of all vehicles, including the Mazda 3. They are responsible for reaching and maintaining your desired speed as well as getting the best fuel economy for your vehicle. When issues arise you may not notice anything more than some clunky gear changes, but you must act fast to fix these issues before they cause any serious hazards or dangerous conditions on the roads. If you’re wondering how to reset the Mazda 3 transmission control module, it’s easy and only takes a few simple steps.

How to Spot Mazda 3 Transmission Issues

Vehicles fitted with automatic transmissions will have a TCM component used to choose the ideal gear during motion. If you’re facing issues with your TCM then you may notice the issues spread to cause problems with your vehicle fuel economy and driving performance too.

Common signs of a bad transmission control module include:

  • Unpredictable shifting pattern
  • Trouble reaching higher gears
  • Engine light on the dash
  • Poor fuel economy 

Let’s take a closer look at these issues and how to spot the signs of problems with your transmission control module.

Unpredictable shifting

Your TCM sends the signals needed to shift gears in your vehicle, so if you find your vehicle is shifting into the wrong gear or even into neutral without any warning this is a key sign of a fault. You must get this checked out as soon as possible, as it can be dangerous and cause accidents as you won’t have full control of your vehicle.

Problems Shifting into Higher and Lower gears

2013 mazda 3 transmission control module

With automatic vehicles, you will notice the transmission shifts into lower gears as you are gradually slowing, and higher gears when you increase speed on the freeway.

If this doesn’t happen at the right time due to a TCM fault then you may find your vehicle struggling to reach higher speeds with your RPM increasing instead of dropping as you upshift which means you may never reach the higher speed and full potential of the engine of your vehicle. 

Alternatively, you may find an issue with downshifting when you lower your speed. This should cause the transmission controls to lower the gear you need until you come to a stop, but in some cases, you may stay in high gear and not be able to take off from the first gear after stopping.

Being stuck in the same gear

If your vehicle is stuck in first or neutral gear then your transmission may not shift at all causing your vehicle to not move, or even never shift up from the first gear leading to very slow speeds.

All of these issues can lead to poor fuel economy as the optimal gears aren’t being selected leading to poor fuel efficiency and sometimes your check engine light can appear illuminated on your dash. If this happens around the same time as you begin to notice issues with your shifting then it would be advised to seek help from a professional who can use a scan tool to find the root cause of your vehicle issues.

The TCM is a vital part of your car that modern vehicles use in the replacement of hydraulic or mechanical transmission for better performance. Although they do not require replacement, if you are experiencing problems with it then this can require a professional fix.

If you require additional help to replace your TCM you should always seek professional help from a local garage or mechanic.  But in case you’re wondering, the transmission control module is located directly on the roof of the transmission, just under the battery tray.

How to Reset Mazda 3 Transmission Control Module

These steps are tailored for the 2010 Mazda 3 model but work for all other models too.  You must do this when you have some spare time as these steps can take a few hours to complete from start to finish.

  1. Start by removing the terminals and leaving them off for a few hours. This will work to drain the charge from the capacitors. 
  2. Cold start your engine making sure to keep your foot on the brake at all times. Move transmission between the park and your lowest gear three times, minimum.
  3. Drive your car for five minutes at a slow speed with low acceleration. Do not go over 25km/h and stick to quiet streets.
  4. Decelerate without using the brake to come to a full stop, then idle for a minute or two before bringing your vehicle to a stop.
  5. After sitting for a minute, put your foot on the brake and move transmission from the park back into the lowest gear.
  6. Repeat the process with another 5-minute drive at a higher speed, but do not exceed 80km/h. 
  7. Again, decelerate without braking to a full stop and idle for a few minutes. 
  8. After these steps avoid hard acceleration and braking for the next 80 km.
