Repair Instructions
Important:
* Perform the Service Fast Learn Adapts (See: Transmission and Drivetrain/Automatic Transmission/Transaxle/Testing and
Inspection/Programming and Relearning) following all transmission related repairs.
* Before replacing the TCM, perform the Control Solenoid Valve and Transmission Control Module Assembly Inspection (See:
Transmission and Drivetrain/Automatic Transmission/Transaxle/Testing and Inspection/Component Tests and General
Diagnostics/6T70/6T75 - Automatic Transmission/Control Solenoid Valve and Transmission Control Module Assembly Inspection).
Perform the Diagnostic Repair Verification (See: Verification Tests) after completing the diagnostic procedure.

DTC Descriptor
DTC P0751
- Shift Solenoid (SS) 1 Valve Performance - Stuck Off
DTC P0752
- Shift Solenoid (SS) 1 Valve Performance - Stuck On
Circuit/System Description
The shift solenoid (SS) valve 1 is part of the control solenoid valve assembly. The SS valve 1 is a normally closed (NC) solenoid valve and controls
fluid to the clutch select valve 2. The solenoid operates by the transmission control module TCM opening or closing the ground circuit. With the
solenoid circuit grounded, solenoid on, the internal plunger moves and allows the metering ball to move away from the feed seat and against the
exhaust seat, creating signal fluid pressure. The signal fluid acts against the clutch select valve 2 to overcome the valve spring force, moving it to
the apply position.
Conditions for Running the DTC
P0751
* The ignition voltage is greater than 8.6 volts.
* The engine speed is 400 RPM or greater for 5.0 seconds.
* The throttle position signal is valid.
* The engine torque signal is valid.
* The output shaft speed is greater than 0 RPM or the throttle position is greater than 0.4 percent.
