Powerflow
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.
Fail-safe Mode
Because both SSE and SSB apply the clutches they control when they are turned OFF, 5th gear is the fail-safe. This transmission defaults to 5th gear when certain failures are detected. 5th gear is provided hydraulically with no electrical input.
