Abstract
A method for mitigating powertrain abuse on a grade can include determining the grade a machine is on, the machine including an impeller clutch located between an engine and a powertrain so as to connect and disconnect engine power from the powertrain; and if the grade is over a threshold, a controller ignores any operator input to the impeller clutch such that machine speed retarding is utilized to keep the machine at a proper speed.
