Features:

Plug & Play: The software and settings will not be modified, making this module plug and play. No software reload, coding or calibration is required after installation.

Completely Reworked PCB: During the TCM remanufacturing the internal circuit board is completely removed from the housing and is tested at the component level. Any known prone-to-failure parts that are close to the maximum tolerance are automatically replaced.

Quality Tested: All TCMs undergo rigorous tests on our specialized custom-built CAN-bus driven testbed. All functions, shift performance, DTCs, and software are checked and verified for proper operation.

PCB Encapsulation: Once the repair and testing process is completed the PCB is fully encapsulated in a special, low viscosity silicone coating that provides maximum protection against heat, vibration, and outside elements.

Powder Coating: Mazda’s TCM housing is made from cast-aluminum that oxidizes very heavy over time. To prevent this from happening all housings are sand-blasted, powder-coated, and baked in the oven.

Turnaround Time: The entire TCM remanufacturing process takes between 3 to 4 days. This is because it takes 24 to 30 hours to remove the existing conformal coating and fully clean the circuit board and another 24 hours for the new encapsulating to fully cure. In addition to PCB repair time and powder-coating process.

Lifetime Limited Warranty: This module comes with our Lifetime Limited Warranty. Please see here for more information.
