How Our Mazda 3 TCM Exchange, Repair and Return Service Works

Are you ready to repair your vehicle and send in your part for repair?! Visit our website and follow the steps below:

Placing Your Order

First, you’ll need to enter your TCM Transmission Control Module part number (located next to the Mazda logo). In case you can’t physically see the TCM TCU on top of the transmission (under the battery housing) after you’ve removed the battery, you can call the Mazda Parts Department and they will provide you with this information.

Second, our program for exchange services requires that you provide your vehicle’s VIN number and for you to select “TCM Update/ Programming (VIN & Firmware)” before proceeding to the next step.

Third, select the 4 characters in front of your part number to verify that we have the correct TCM Transmission Control Module for your vehicle in stock. We keep our inventory numbers available per part updated daily so that you’re aware of our ability to meet your needs- we’re big on transparency and respect both your time and ours.

Next, select “Place Your Exchange Order” and proceed to complete the checkout process to receive your good and tested TCM TCU for your Mazda 3 within 2-3 business days. Furthermore, we will include a red paper reminder with your package to send in your original TCM core.

Receiving Order

Upon receiving your order, please verify the exchange Mazda 3 2006-2014 Transmission Control Module TCM we sent you works without issue. You should confirm there is not a check engine light or error lights, the vehicle shifts smoothly, and no hesitation occurs when the vehicle accelerates.

Select "Place Your Exchange Order" for Mazda 3 TCM Exchange Service.

Exchange TCM Installation Tips

Prior to removing or re-installing any electrical unit, we strongly recommend disconnecting the negative battery terminal. Doing so helps prevent fuses/relays from blowing, fault codes, or communication issues occurring.

In fact, one of the main reasons the Mazda 3 TCM fails is due to insufficient heat dissipation. When mounted directly to the transmission, the TCM overheats and eventually fails. In order to extend the life of your rebuilt TCM, we highly recommend re-locating your TCM on the brake lines near the firewall with plastic zip-ties to secure it. Since this area has optimal airflow, it will allow the TCM to operate under cooler temperatures. If you need instructions on how to do this, please visit our step-by-step guide available and installation videos.

Send Your Original Transmission Control Module To Us

Last, ship your refundable core unit back to us within 30 days with the return shipping label we emailed you to receive your original core refund and activate your warranty. Finally, we process your refund the same day we receive your original core unit and we’ll send you an email to notify you we’ve received it. Though we do initiate the core refund process the same day we receive your shipment, it can take 3-5 business days for the refund to be completed.
