Pinpoint Test E : DTCS P0770, P0773, P0774
- Refer to Transmission Controls - 6F35
for schematic and connector information.
Normal Operation and Fault Conditions
SSE controls the multiplexing of the SSD low/reverse and overdrive clutch. If SSE fails off (no pressure) then 1st gear is failed to 4th gear. If clutch select valve 2 sticks in the default position then 1st gear with engine braking is failed to 4th gear and reverse is failed to neutral. SSE is an On/Off solenoid.
DTC Fault Trigger Conditions
DTC Description Fault Trigger Condition PCM P0770:00 Shift Solenoid "E": No Sub Type Information Open, short to power or short to ground in the solenoid or wire harness. PCM P0773:00 Shift Solenoid "E" Electrical: No Sub Type Information Open or short to ground in the solenoid or wire harness. PCM P0774:00 Shift Solenoid "E" Intermittent: No Sub Type Information Intermittent circuit in the solenoid or wire harness open, shorted to ground or shorted to power. Possible Sources
- Connectors damaged or pushed-out terminals, corrosion, loose wires and missing or damaged seals
- SSE
- Transmission internal wiring harness frame
- PCM
- E1 RETRIEVE AND RECORD ALL DTCS
- Using the diagnostic scan tool, retrieve all diagnostic trouble codes (DTCs).
Are diagnostic trouble codes (DTCs) P0770, P0773 and/or P0774 present?
Yes GO to E2 No REFER to: Diagnosis By Symptom . - E2 CHECK THE SHIFT SOLENOID E (SSE) CONTROL CIRCUIT FOR AN OPEN
- Ignition OFF.
- Disconnect Transmission Vehicle Harness C168A.
- Disconnect PCM C175E.
- Inspect the connectors for damaged or pushed-out terminals, corrosion, loose wires and missing or damaged seals.
Is the resistance less than 3 ohms?
Yes GO to E3 No REPAIR the circuit. - E3 CHECK THE SHIFT SOLENOID E (SSE) CONTROL CIRCUIT FOR A SHORT TO GROUND
- Measure:
Positive Lead Measurement / Action Negative Lead C168A-7 Ground
Is the resistance greater than 10, 000 ohms?
Yes GO to E4 No REPAIR the circuit. - Measure:
- E4 CHECK THE SHIFT SOLENOID E (SSE) CONTROL CIRCUIT FOR A SHORT TO POWER
- Ignition ON.
- Measure:
Positive Lead Measurement / Action Negative Lead C168A-7 Ground
Is any voltage present?
Yes REPAIR the circuit. No GO to E5 - E5 CHECK THE SHIFT SOLENOID E (SSE) FOR AN OPEN
- Measure:
Positive Lead Measurement / Action Negative Lead Component side resistance pin 7. Component side resistance pin 5.
Is the resistance between 15 and 34 ohms?
Yes Refer to PCM Guided Routine Testing . No GO to E6 - Measure:
- E6 CHECK SHIFT SOLENOID E (SSE) RESISTANCE
- Remove the transmission internal wiring harness frame. REFER to: Transmission Internal Wiring Harness Frame . Inspect for metal shavings on the exposed metal contacts or other components and clean the solenoid and transmission internal wiring harness frame terminals.
Is the resistance between 15 and 34 ohms?
Yes GO to E7 No INSTALL a new SSE. REFER to: Solenoid . - E7 CHECK SHIFT SOLENOID E (SSE) FOR A SHORT TO GROUND
Is the resistance less than 3 ohms?
Yes INSTALL a new SSE. REFER to: Solenoid . No INSTALL a new transmission internal wiring harness frame. REFER to: Transmission Internal Wiring Harness Frame .
