摘要： A shift quality error detection system for an automatic transmission includes a vehicle acceleration determination module to determine a vehicle acceleration. An acceptance window module defines upper and lower limits of a desired vehicle acceleration. The shift quality error detection module compares the determined vehicle acceleration to the upper and lower limits of the desired vehicle acceleration. A shift quality error detection module selectively provides a shift quality error based on the comparison. A method of detecting shift quality error of an automatic transmission comprises determining a vehicle acceleration during a transmission gear shift. The method also includes comparing the vehicle acceleration to an acceptance window of desired vehicle accelerations and outputting an error signal based on the acceleration comparison.
