Various disclosed embodiments include illustrative controller units, vehicles, and methods. In an illustrative embodiment, a controller unit includes a processor and a memory. The memory is configured to store computer-executable instructions configured to cause the processor to receive a request to perform a mechanical load transition between a motor and a mechanical load, send a torque request to the motor responsive to the received request, receive a motor speed value, determine status of the mechanical load transition responsive to the received request and the motor speed value, and output the determined status.
