Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Electronically Controlled Continuously Variable Transaxle (CVT): Notes
The primary objective of the electronically controlled CVT is to deliver torque to the drive axles of the vehicle. The CVT transmits input torque from the internal combustion engine, or uses electrical power from the high voltage traction battery. The electrical power is converted into mechanical power by the traction motor and the generator motor. The electronically controlled CVT operates in several different modes, and under certain conditions can transmit power from the traction motor and engine simultaneously or independently. For additional information, refer to HYBRID ELECTRIC CONTROL SOFTWARE , operating modes.
The key electronically controlled CVT components are:
- planetary gear set
- generator motor
- traction motor
- transaxle control module (TCM)
