3-5-Reverse Clutch Releases

35R Pressure Control (PC) Solenoid 

If the transmission is in Third or Fifth gear when an electrical condition commands a protection mode, the 35R PC solenoid defaults to its normally-low state (OFF), allowing PCS 35R clutch fluid pressure to exhaust and the 3-5-reverse clutch to release. See Drive Range- Fourth Gear for a complete description of 3-5-reverse clutch release.
