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.

Diagnostic Fault Information



Typical Scan Tool Data



Circuit/System Description



The shift control solenoid (SLC3) is installed on the front valve body. The solenoid linearly control hydraulic pressure in response to signals output



from the transmission control module (TCM). Through this, the SLC3 controls operating hydraulic pressure to the clutch 3 for smooth shifting.



According to each shift control solenoid assembly, the transmission shifts from 1st gear into 6th gear and vice versa. As a fail-safe function, if any



shift control solenoid assembly abnormality occurs, the TCM will disable the current to the solenoids.
