How to Deal with the Failure of the Mechatronic Unit in the Magotan Transmission?

If the mechatronic unit in the Magotan transmission fails, the solution is to replace it and then upgrade the control software using a computer. Below are the specific details about the transmission mechatronic unit: 1. Working Principle: The transmission mechatronic unit controls the operation of the automatic transmission through solenoid valves. It processes input circuits, connecting signals from sensors and other devices. These signals are processed, impurities are filtered out, and then amplified. They are then converted into electrical signals to drive the solenoid valves. 2. Functions: Using the mechatronic unit for control allows precise management of the solenoid valves, enabling the transmission to operate more efficiently and accurately. This results in smoother vehicle driving and improved fuel efficiency. The mechatronic unit can connect to the system, fully enabling electronic gear shifting. After removing the transmission oil pan, the mechatronic unit becomes visible. Below the unit, there is an aluminum valve body with cylindrical plungers inside. The valve body is equipped with multiple solenoid valves that perform various detection functions.
My Magotan also had a mechatronic unit failure before. The gear shifts were not smooth while driving, and occasionally even got stuck. I immediately drove to the 4S shop for inspection. The technician used a computer diagnosis and found an internal circuit short in the mechatronic unit. The solution was to replace the mechatronic unit part, which cost over 5,000 yuan including labor. After the replacement, the car returned to normal. I learned from this that regular maintenance is crucial—changing the transmission oil every 20,000 kilometers, avoiding sudden acceleration and hard braking, can also extend the life of the mechatronic unit. If such issues are ignored, the transmission could be completely ruined, leading to even more expensive repairs. Therefore, addressing abnormalities early is much more hassle-free than delaying.
Dealing with the mechatronic unit failure of a Magotan by yourself carries certain risks. I tried using an OBD scanner to read the codes and confirm the fault, which turned out to be a sensor malfunction. However, disassembling the unit requires professional knowledge, so I ended up having the entire module replaced at a repair shop. In terms of cost control, choosing a professional shop cost around four thousand yuan to resolve the issue. Non-experts should avoid blind DIY attempts to prevent damaging more components. It's recommended that car owners invest in a good diagnostic tool for regular checks and seek professional help promptly if any abnormalities are detected, ensuring both safety and cost savings.
The repair cost for a malfunctioning mechatronic unit is not low. At the dealership, I spent nearly six thousand yuan to replace it with a new unit. Opting to repair the old part might save half the cost, but it's time-consuming and the lifespan is uncertain. As a car owner, I prioritized safety and paid the full amount for a new unit. Don't take risks to save money—if the unit fails while driving, it could lead to more serious trouble. Regular transmission inspections can also prevent similar issues and reduce expenses.
