AC Delco 6L80 Output Speed Sensor - 213-4579

Genuine AC Delco Output Speed Sensor for GM 6L80 automatic transmissions. Speed sensors are critical inputs to the transmission control module providing real-time rotational speed data used to calculate shift points, TCC engagement timing, and line pressure adjustments for optimal shift quality under all driving conditions.

A failing speed sensor causes erratic shifting, speedometer malfunction, diagnostic trouble codes P0716 through P0722, and can trigger limp mode forcing the transmission into a single gear ratio. This OEM replacement ensures accurate signal output and reliable transmission operation. Always verify sensor resistance before installation.
