CIRCUIT DESCRIPTION:The Pressure Switch Manifold (PSM) is a multiple-switch assembly made up of three Normally Open (N/O) and one Normally Closed (N/C) pressure switches. The Pressure Switch 2 (PS2) monitors the SS2 valve positioning and relays it to the TCM. When PS2 is in the open state, SS2 valve should be in the destroked position. DTC P0756 sets when the SS2 valve is commanded on and PS2 status remains Exhausted/OFF for a period of time that is temperature dependent. The intent of this DTC is to detect a shift valve timeout condition which normally indicates a stuck shift valve in...

CIRCUIT DESCRIPTION:The Pressure Switch Manifold (PSM) is a multiple-switch assembly made up of three Normally Open (N/O) and one Normally Closed (N/C) pressure switches. The Pressure Switch 3 (PS3) monitors the SS3 valve positioning and relays it to the TCM. When PS3 is in the open state, SS3 valve should be in the destroked position. DTC P0761 sets when the SS3 valve is commanded on and PS3 status remains Exhausted/OFF for a period of time that is temperature dependent. The intent of this DTC is to detect a shift valve timeout condition which normally indicates a stuck shift valve in...

The Pressure Switch 3 (PS3) monitors the SS3 valve positioning and relays it to the TCM. When PS3 is in the open state, SV3 valve should be in the destroked position. DTC P0762 sets when the SS3 valve is commanded off and PS3 status remains Pressurized/ON for a period of time that is temperature dependent. The intent of this DTC is to detect a shift valve timeout condition which normally indicates a stuck shift valve in...

CIRCUIT DESCRIPTION:Pressure Control Solenoid 2 (PCS2) controls oncoming, off-going, and holding pressure to any one of the five clutches. This solenoid is referred to as a Pressure Proportional to Current (PPC) solenoid since the output hydraulic pressure supplied by this solenoid is proportional to the controlled current command. The TCM uses information from the turbine and output speed sensors to detect if a clutch is slipping. The clutch being controlled by PCS2 varies depending on the shift that was being completed. DTC P0776 sets when the TCM detects an incorrect oncoming ratio (range-to-range) for an accumulated number of occurrences. ACTION...
