This product is a transmission sensor, identified by the OE number 8L45. Transmission sensors are crucial components within modern automatic transmissions.1 They monitor various operating parameters of the transmission, such as speed, temperature, pressure, and fluid level.2 This information is then relayed to the transmission control module (TCM) or engine control unit (ECU), which uses this data to make real-time adjustments to gear shifting, torque converter lockup, and other transmission functions.3 A properly functioning transmission sensor is essential for accurate transmission control, smooth and precise gear shifts, optimal fuel efficiency, and the overall performance and longevity of the automatic transmission.4 A faulty or failing transmission sensor can send incorrect or no signals to the TCM/ECU, leading to a range of transmission problems, including incorrect gear shifting, harsh or erratic shifting, slipping gears, failure to shift, transmission warning lights, reduced performance, and potential internal transmission damage.5 This Sensor 8L45 Automatic Transmission Sensor is engineered to meet or exceed original equipment (OE) specifications for sensor accuracy, signal output, and durability, ensuring a proper fit and reliable function within your Buick's transmission system. It is a New part, manufactured in China, guaranteeing high quality and adherence to manufacturing standards.
