A method for providing over learn protection for torque steer mitigation includes receiving a compensation torque value corresponding to a torque offset associated with a transmission torque and receiving a handwheel torque value associated with a handwheel of a steering system. The method also includes detecting a mathematical sign of the compensation torque value, detecting a mathematical sign of the handwheel torque value, and determining whether the mathematical sign of the compensation torque value is the same as the mathematical sign of the handwheel torque value. The method also includes, in response to a determination that the mathematical sign of the compensation torque value is not the same as the mathematical sign of the handwheel torque value, adjusting one or more learned gains, and generating an inverted compensation torque value by inverting the mathematical sign of the compensation torque value.
