First things first:
Have problems begun?
Is the car running in emergency mode?
Problems with the MAZDA automatic gearbox control module appear suddenly and do not depend on the season of year and the mileage of the car.
Do not rush to go to the auto repair shop for automatic transmission; it is often sufficient to reset your TCM (Transmission Control Module).
Symptoms of MAZDA TCM faulty in the car are:
- Strong "kick" when switching automatic grip from position "P" to position "R"
- Indication on the dash fascia "Check Engine"
, "AT" 
, "ABS" 
, "Slippery Road" (ESP) 
etc.
- Gearbox does not go to "manual mode"
- The car goes in emergency mode only
Typical OBD error codes are
- Error u0073 - control Module Communication Bus "A" is off (the e-Data bus control is disabled)
- Error U0100 - Lost Communication with ECM/PCM "a" error (data bus, engine control module (ECM) "A"-no link)
- Error u0101 - Lost Communication with TCM (data bus, transmission control module (TCM) - no link)
- Error p0715 - Input/Turbine Speed sensor "A" Circuit (the rotation frequency sensor of the input shaft of automatic gearbox (Hydrotransformer turbine)- Electrical circuit failure)
- Error P0720 - Output Speed sensor Circuit error (shaft rotation frequency sensor - fault of electrical circuit)
- Error p0744 - Torque Converter Clutch Circuit Intermittent (Electromagnetic valve coupling of a hydro transformer - unreliable pin of the electrical circuit)
- Error p0745 - Pressure control solenoid valve manifold "A" (Gearbox Electromagnetic fluid pressure control valve - electric circuit fault)
- Error p0748 - Pressure control solenoid valve manifold "A" Electrical Gearbox (electromagnetic pressure control valve - electrical malfunction)
- Error p0753 - Shift solenoid valve manifold "A" Electrical (Gearbox electromagnetic valve A - electrical malfunction)
- Error p0758 - Shift solenoid valve manifold "B" Electrical (Gearbox electromagnetic valve B in - electrical malfunction)
- Error p0763 - Shift solenoid valve manifold "C" Electrical (Gearbox electromagnetic valve C in - electrical malfunction)
- Error p0768 - Shift solenoid valve manifold "D" Electrical (Gearbox electromagnetic valve D - electrical malfunction)
- Error p0773 - Shift solenoid valve manifold "E" Electrical (Gearbox electromagnetic valve E in - electrical malfunction)
- Error p0778 - Pressure control solenoid valve manifold "B" electrical (electromagnetic valve B in pressure control - electrical malfunction)
- Error p0791 - Intermediate Shaft speed sensor "A" Circuit (intermediate shaft frequency sensor - failure of the electrical circuit)
- Error P0841 - Transmission Fluid Pressure sensor/Switch "A" error - Circuit Range/performance (sensor A of the pressure of the work fluid of gearbox - band/function)
- Error P0882 - TCM Power Input Signal Low (Gearbox electronic control module - low power supply voltage)
- Error P0883 - TCM Power Input Signal Low (Gearbox electronic control module - high power supply voltage)
- Error p0884 - TCM Power Input Signal Intermittent (Gearbox electronic control module (TCM), input power signal - unreliable pin of the electrical circuit)
- Error p2709 - Shift solenoid valve manifold "F" Electrical (electromagnetic valve F gear switches - electrical malfunction)
- Other errors (in rare cases)

* If your Transmission Control Module is not on the list, but it looks like the photograph above, there is high chance to repair it.
Plan of Action:
Car Diagnostics
The first step is the most important! The source of your troubles must be determined. To do this, you need to go to a qualified electrician to do the following:
- Computer diagnostics of your car. You note error codes to convey information to us.
- Check the electrical wiring of the vehicle to detect damage to the circuits.
- Verifying the TCM connector for oxides. Check the quality of the pin in the slot.
If you do not have the ability to do this, please contact us and we will try to resolve this issue.
Determination of repair time and cost.
After you have identified the exact "diagnosis", the time for the second step comes. You're getting in touch with us. We determine the starting date of the work. After hearing you we determine the preliminary cost of the troubleshooting work in your TCM.
TCM delivery to us
The third step is your task of bringing TCM yourself to our office or sending with a courier, a shipping company, right to the office! Delivery is paid by the customer!
Diagnosis and repair of Mazda TCM
After we receive your TCM, we performs a primary diagnostic. After we receive your Mazda TCM, we performs a primary diagnostic. After this we repair the electronic control unit of the Mazda.
Pay for work
When the repair is complete, you receive information about the readiness of your TCM. Only then the payment occurs. You can pay cash in our company's office, and use cashless transfers. The payment methods are negotiated with the customer individually.
TCM delivery to you
The final step remains to deliver your TCM to you. You can take it on your own or call a courier from a transport company. You can ship to the transport company's office in your city. The delivery is paid by the customer!
Summing up
We have been repairing Mazda since 2011. Many of the companies involved in the repair of MAZDA automated gearbox are cooperating with us, guaranteeing their customers a quality service.
The main benefits of cooperation with us are:
- Our warranty is 6 months independent of vehicle mileage
- We eliminate all problems that can "get out" while the data is being exploited by MAZDA TCM in independence from errors to repair
- We use high-quality electronic components only and a special compound to fill MAZDA TCM
We guarantee high quality of service. Beware of yourself and your time!
