Speed sender for 4-speed Automatic, 01M transmissions. One of two sensors, this sensor specifically interacts with the transmission control module to determine shift points. A failed sender can cause the transmission to stay in a lower gear.
This sensor uses a D-shaped connector. If your vehicle's sensor uses a square shaped, black connector, you will need the "A4 Automatic Square" style speed sensor. If your sensor does not look like the one pictured here, please see the Transmission Speed Sensor G68 (A4 Automatic Square)
