Pinpoint Test H : Torque Converter Clutch Solenoid: Notes
WARNING: This page is about a different variant/trim than selected.
Diagnostic Overview
Diagnostics in this article assume a certain skill level and knowledge of Ford-specific diagnostic practices. Refer to Diagnostic Methods in Service Information for information about these practices.
Refer to Transmission Controls-6F35 for schematic and connector information.
Normal Operation and Fault Conditions
The TCM controls the torque converter lock-up by varying the amount of current applied to the TCC solenoid. When no current is applied to the TCC solenoid, the TCC is fully released. When maximum current is applied, the TCC is fully applied.
