2-6 Clutch Releases

26 Pressure Control (PC) Solenoid 

If the transmission is in Second or Sixth gear when an electrical condition commands a protection mode, the 26 PC solenoid defaults to its normally-low state (OFF), allowing PCS 26 clutch fluid pressure to exhaust and the 2-6 clutch to release. See Drive Range- Third Gear for a complete description of 2-6 clutch release.
