Apparatuses, methods and systems comprising vehicle gear shifting controls are disclosed. One embodiment is a method comprising operating a vehicle system comprising an engine structured to output torque, a transmission structured to receive torque from the engine and output torque to one or more ground contacting wheels, and an electronic control system in operative communication with the engine and the transmission. The electronic control system is structured to estimate an engine load parameter using one or more dynamically determined vehicle operating parameters, set an engine load threshold using the engine load parameter, evaluate a current engine load relative to the engine load threshold, and selectably perform an operation to control or influence a shifting event in response to the evaluation.
