瀚慖f any test status parameter displays Fault or Malfunction, replace the control solenoid valve assembly.

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.

Circuit/System Description

The shift control solenoid (SLC1) 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 SLC1 controls operating hydraulic pressure to the clutch 1 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
