Circuit/System Testing
WARNING: This page is about a different variant/trim than selected.
- Perform the Line Pressure Check
.
- If the pressure is out of specification correct that concern first.
- Perform the Control Solenoid Valve and Transmission Control Module Assembly Inspection
.
- If a concern is found, repair or replace the control solenoid (w/body and TCM) valve assembly.
- Perform the Control Solenoid Valve and Transmission Control Module Assembly Solenoid Performance Test
.
- If the shift solenoid 1 is found to be stuck On (not allowing exhaust), replace the control solenoid (w/body and TCM) valve assembly.
- If the control solenoid (w/body and TCM) valve assembly shift solenoid functions correctly, inspect the lower control valve body assembly for the following:
- Control solenoid (w/body and TCM) valve assembly filter plate for sediment or debris that could block the apply fluid.
- Clutch select solenoid valve and valve body bore for scratches, gouges, scuffing, scoring, and sediment.
- The valve should move freely in the bore without stopping or binding.
- Inspect clutch select valve 2 (CSV2) fluid circuits for blockage.
