Does Replacing the Mechatronic Unit Count as a Major Overhaul?

[KeiraLee]

Replacing the mechatronic unit counts as a major overhaul. During the replacement process, the entire transmission needs to be disassembled. Any disassembly and repair of the transmission can be considered a major overhaul. Below is relevant information about the transmission mechatronic unit: Function: The transmission mechatronic unit is the control center of the transmission. The input circuit of the mechatronic unit receives signals from sensors and other devices, then filters, processes, and amplifies these signals before converting them into electrical signals to drive the controlled solenoid valves. The mechatronic unit also controls the vehicle's shifting logic, ensuring the transmission better matches the engine's operating state, thereby enhancing the vehicle's power, acceleration, and smoothness with higher controllability. Relationship with Temperature: The damage to the mechatronic unit is largely related to high transmission temperatures. During aggressive driving, the temperature inside the clutch plates or torque converter can become very high. High temperatures can cause the electronic control unit to malfunction, and when this happens, replacing the unit is usually the only solution.
