More Information
Summary:A method for operating an automatic transmission with resistance change in a control system of the automatic transmission includes detecting an electrical resistance increase in a control loop for a shift element actuator of the automatic transmission, adjusting an electrical current to the shift element actuator in response to the electrical resistance increase, and shifting the automatic transmission to a gear in which the shift element is in the open operating state. A related control device for an automatic transmission is also provided.
