The equipment measuring transmission errors of gears under load for assembled automotive transmissions is developed. This instrument can measure a manual transmission for front engine-front drive accurately without alteration and separate out the transmission error of each gear from measured data by discrete Fourier transform. Considering and adjusting resonance of the system united a test transmission with the measuring machine make measuring absolute value possible. The precision of measured transmission errors is confirmed by the comparison between measured values and calculated values from tooth surface. It is also shown that measured transmission errors correspond to gear whine noises.
