Product Details

NTK AU0030 is part of NTK’s technical sensor lineup, a product line developed from the brand’s long OE background in ignition and oxygen sensor technology. For transmission service, this sensor is used to monitor output shaft speed so the vehicle’s control system can manage shifting strategy and speed-related transmission data. It is a direct-fit replacement for many 2010-2017 Buick, Chevrolet, and GMC models, including Buick Encore, Chevrolet Cruze, Chevrolet Malibu, Chevrolet Sonic, Chevrolet Trax, and GMC Terrain. This part cross-references Standard Ignition SC471 for the same application.

What It Helps Address

• Erratic or delayed shifting related to incorrect output speed input
• Transmission warning lights triggered by speed sensor faults
• Harsh or inconsistent shift behavior caused by sensor signal loss
• Speedometer or transmission data issues tied to output sensor failure
• Diagnostic trouble codes associated with transmission speed sensing

Installation Notes and Tips

Verify connector style, terminal count, and harness length before installation. Confirm the sensor location as the transmission output position and inspect the connector, wiring, and sealing surfaces for damage or contamination. On vehicles such as the Chevrolet Cruze, Buick Verano, and GMC Terrain, matching the OE-style connector and harness routing helps support a clean replacement. Clear any stored transmission codes after installation and road test the vehicle to confirm proper signal operation.

Quality Assurance

NTK sensors are produced using OE-based engineering and are tested under thermal shock, vibration, and OBD verification conditions. The AU0030 is manufactured to meet or exceed OE specifications for the listed applications, supporting dependable service in compatible Buick, Chevrolet, and GMC output-speed sensor applications.
