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.

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.
