DTC P0776

- Clutch Pressure Control (PC) Solenoid 2 - Stuck Off

DTC P0777

- Clutch Pressure Control (PC) Solenoid 2 - Stuck On

Circuit/System Description

The clutch pressure control (PC) solenoid 2 is part of the control solenoid valve assembly, which has no serviceable components. The PC solenoid

2 regulates transmission fluid pressure to the 3-5-Reverse clutch regulator valve which controls pressure to the 3-5-Reverse clutch. The

transmission control module (TCM) calculates gear ratio based on the RPM signals from the input speed sensor (ISS) and the output speed sensor

(OSS). The TCM compares the expected transmission gear ratio to the calculated gear ratio for each commanded gear.

DTC P0989

- Transmission Fluid Pressure (TFP) Switch 5 Circuit Low Voltage

DTC P0990

- Transmission Fluid Pressure (TFP) Switch 5 Circuit High Voltage

Diagnostic Fault Information

Typical Scan Tool Data

Circuit/System Description

The transmission fluid pressure (TFP) switch 5 is part of the control solenoid valve assembly which has no serviceable parts. The TCM supplies a

signal circuit to the TFP switch 5. The TFP switch 5 has an internal case ground. TFP switch 5 is normally closed or LOW. When oil pressure is

present at the TFP switch 5, the switch is open or HIGH. The normally high pressure control (PC) solenoid 3 controls pressure to the CBR1/4-5-6

clutch regular valve. The TCM monitors the TFP switch 5 signal circuit to determine the position of the CBR1/4-5-6 clutch regulator valve. When

the 4-5-6 clutch is commanded OFF, pressure is present on the TFP switch 5. When the 4-5-6 clutch is commanded ON, the CBR1/4-5-6 clutch

regulator valve moves and pressure to the TFP switch 5 is exhausted through the CBR1/4-5-6 clutch regulator valve.

Conditions for Running the DTC

P0989 or P0990

Conditions for Setting the DTC

P0989

The TCM detects that the TFP switch 5 signal voltage remains LOW after the 4-5-6 clutch transitions from a HIGH pressure state to a LOW

- Clutch Pressure Control (PC) Solenoid 5 Control Circuit High Voltage

Diagnostic Fault Information

Typical Scan Tool Data

Circuit/System Description

The clutch pressure control (PC) solenoid 5 is part of the control solenoid valve assembly which has no serviceable parts. The normally low PC

solenoid 5 regulates and directs oil pressure to the 1-2-3-4 clutch regulator valve and 1-2-3-4 clutch boost valve. Increasing PC solenoid 5 pressure

increases pressure to the 1-2-3-4 clutch. The TCM varies the current to the PC solenoid 5 through a low side driver. Increasing the current to PC

solenoid 5 increases oil pressure by closing OFF the solenoid exhaust port. Decreasing the current to PC solenoid 5 decreases oil pressure by

opening the exhaust port. PC solenoid 5 power is supplied by the TCM through a high side driver (HSD). The HSD protects the circuit and

components from excessive current flow. If excessive current flow is detected, the HSD will turn OFF. When the fault is corrected, the HSD will

reset.

Diagnostic Fault Information

Circuit/System Description

The automatic transmission fluid temperature sensor provides transmission fluid temperature to the transmission control module (TCM). The TCM

supplies a 5 V reference signal to the sensor. The automatic transmission fluid temperature sensor is a variable resistor that measures the

temperature of the transmission fluid and is a thermistor, or a resistor that changes value when the temperature changes. The sensor has a negative

temperature coefficient. This means that as the temperature increases the resistance decreases and vice versa. The TCM will compare the

temperature difference between the engine coolant temperature sensor and the automatic transmission fluid temperature sensor to determine if the

temperatures are within an acceptable operating range of each other. This fault is handled inside the TCM and no external circuits are involved.

Conditions for Running the DTC

P0711

* The ignition voltage is 10.2-15.5 V.

* The engine speed is greater than 400 RPM for 2 s.

* TCM communication is normal.
