Systems and methods for reporting on vehicle characteristics determined by the control system of a multi-speed automatic transmission of a vehicle are provided. The control system may output a vehicle mass alert based on a relationship between a vehicle mass threshold and a determined vehicle mass satisfying a condition. The control system may output a vehicle road grade alert based on a relationship between a vehicle road grade threshold and a determined vehicle road grade satisfying a condition.

System and method for reporting on vehicle characteristics determined by transmission control circuit

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.

Manual shifting control system and method for multi-speed automatic transmission

A method of controlling a multispeed transmission includes providing a transmission controller, a plurality of ranges of the transmission of which at least one of the plurality of ranges is defined as a limiting range, and a communication link. The transmission is operated in a first range of the plurality of ranges and the method includes detecting a loss of communication over the communication link between the transmission controller and another controller. The method also includes determining if the first range is defined as the limiting range when communication is lost and commanding a shift from the first range to a second range of the plurality of ranges which is not defined as the limiting range. The method further includes controlling the shift from the first range to the second range.
