摘要:
Systems and methods for managing shift changes of a multi-speed automatic transmission of a vehicle are provided. The multi-speed automatic transmission being capable of establishing a plurality of forward speed ratios. The vehicle may include a transmission shift selector having at least one operator selectable shift request input to request a shift change of the multi-speed automatic transmission. A control circuit operatively coupled to the multi-speed automatic transmission is provided which shifts the multi-speed automatic transmission from a first forward speed ratio to a second forward speed ratio in response to shift criteria. The shift criteria may be based on a plurality of operational characteristics related to the vehicle.
