This component must be engineered to handle torque loads and maintain proper drivetrain alignment to prevent premature wear or failure of the drivetrain components. The radiator and cooling fan assembly from the Leaf must be integrated into the front of the donor vehicle.

Component Function Consideration for Swap AC Induction Motor Propels the vehicle Requires precise adapter plate; verify shaft dimensions Thermal Management System Cools motor and inverter May need external radiator; ensure coolant compatibility High Voltage Battery Energy storage Fitment and safety disconnects are critical Thermal Management and Cooling Solutions The Leaf's thermal management system is designed to cool the motor, inverter, and battery pack using a liquid coolant loop. The controller manages the power flow from the battery and communicates with the pedal assembly.
This transaxle contains the differential and final drive, simplifying the powertrain layout compared to traditional internal combustion engine vehicles. Professional fabricators typically use a precision-machined adapter plate that bolts to the transmission bell housing of the Leaf and matches the bolt pattern of the donor vehicle's differential or clutch housing.

The inverter, a critical component, converts the high-voltage DC battery power into three-phase AC current for the motor. Extracting this unit requires disconnecting high-voltage services and managing the significant weight of the assembly, which is often mounted low to enhance the car's center of gravity.
