ACDelco 24276402 Automatic Transmission Input Speed Sensor

The ACDelco 24276402 Automatic Transmission Input Speed Sensor is a genuine GM OE replacement component designed to monitor the rotational speed of the transmission input shaft. This sensor provides critical data to the vehicle's powertrain control module (PCM) to ensure proper shift timing, torque converter clutch operation, and overall transmission performance.

Key Features:

• Direct OE replacement for reliable fit and function
• Monitors input shaft speed for accurate transmission control
• Helps maintain optimal shift quality and fuel efficiency
• Manufactured to ACDelco's stringent quality standards
• Essential component for proper transmission operation and diagnostics

When the input speed sensor fails, symptoms may include harsh shifting, transmission slipping, illuminated check engine light, or the transmission entering limp mode. Replacing a faulty sensor restores proper communication between the transmission and PCM, ensuring smooth operation and preventing further drivetrain issues.
