Abstract
Systems and methods for diagnosing operation of a transmission warm-up valve are presented. In one example, the transmission warm-up valve is commanded to an open position and an estimated transmission fluid temperature is compared to an actual transmission fluid temperature to determine whether or not the transmission warm-up valve is operating as commanded.
