In 5th gear, SSE is commanded OFF by the PCM/ TCM to apply the overdrive (4,5,6) clutch. SSB is commanded OFF by the PCM/ TCM to apply the direct (3,5,R) clutch. The overdrive (4,5,6) clutch is applied to transfer power from the input shaft to the rear planetary carrier and the direct (3,5,R) clutch is applied to transfer power from the front planetary carrier to the No. 2 sun gear, providing a 0.858 to 1 gear ratio.
