A system for controlling slip of a machine is disclosed. The system has a power source configured to produce a power output, at least one driven traction device, and a transmission operably connected to transmit the power output from the power source to the at least one driven traction device. The system further has at least one sensor configured to detect an acceleration of the machine and to generate a corresponding signal, and a controller configured to receive the signal and to reduce a magnitude of power or torque transmitted to the at least one driven traction device when the detected acceleration indicates slip of the at least one driven traction device.
