Speed sender for early 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 square connector. If your vehicle's sensor uses a D-shaped, black connector, you will need the "A4 Automatic D-Shaped" style speed sensor. If your sensor does not look like the one pictured here, please see the Transmission Speed Sensor G68 (A4 Automatic D-Shaped)
