Abstract

A system for controlling a transmission including a fluid pump and a fluid motor operably coupled to one another in a fluid circuit is disclosed. The system includes a controller configured to receive signals indicative of operator inputs, and determine a variable pressure limit in the fluid circuit based on the signals indicative of operator inputs. The controller is further configured to control displacement of at least one of the fluid pump and the fluid motor based on the variable pressure limit, such that a pressure level in the fluid circuit is maintained below the variable pressure limit.
