A powertrain control system is disclosed for use with a mobile machine. The powertrain control system may have an engine, and a continuously variable transmission operatively coupled to the engine. The powertrain control system may also have an operator input device configured to generate a signal indicative of a desired speed of the engine, a feature selector usable by an operator to select activation of a powertrain control feature, and a controller in communication with the engine, the continuously variable transmission, the operator input device, and the feature selector. The controller may be configured to make a determination that the operator has selected activation of the powertrain control feature via the feature selector, lock a speed of the engine based on the determination and the signal, and lock a torque output of the continuously variable transmission based on the determination and the locked speed of the engine.
