4L80E TCC Lock-Up Solenoid 1991-2013 24210867 AC Delco

AC Delco 4L80E TCC Lock-Up Solenoid - 24210867

Overview

Genuine AC Delco Torque Converter Clutch solenoid for GM 4L80E automatic transmissions.

The TCC solenoid controls the lock-up clutch in the torque converter which is essential for fuel efficiency at highway speeds and preventing transmission overheating during sustained driving conditions. Proper TCC operation reduces fluid temperatures significantly.

A failing TCC solenoid causes shudder during converter lock-up, diagnostic trouble codes P0742 or P0741, and can lead to premature torque converter failure from excessive heat generation.

This OEM replacement ensures proper converter clutch engagement timing and smooth highway driving. The TCC solenoid should always be replaced during rebuilds as a preventative measure.
