NTK Automatic Transmission Speed Sensor AU0029

NTK AU0029 is an automatic transmission speed sensor built for input-speed monitoring in a range of GM vehicles. It uses a rectangular 1-connector design with a male blade terminal layout and an included wiring harness for a direct electrical connection.

Key Features

• Automatic transmission input speed sensor for transmission control feedback
• Rectangular connector with 1 connector, 2 terminals, and male blade terminals
• Wiring harness length: 7.25 in.
• Wiring harness included; mounting hardware not included
• Built by NTK, The Sensor Specialist, with OE-focused sensor coverage
• Cross-reference: Standard Ignition SC472

Product Details

NTK’s technical sensor line draws on more than 80 years of automotive experience and OE application knowledge. AU0029 is manufactured to meet or exceed OE specifications and is tested under thermal shock, vibration, and OBD verification conditions. For drivers and technicians servicing a Buick Encore, Chevrolet Cruze, or GMC Terrain, this NTK automatic transmission speed sensor supports accurate input-speed signal reporting for the transmission control system.

This part cross-references Standard Ignition SC472 for the same application.

What It Helps Address

• Transmission input speed signal loss
• Erratic or inconsistent shift behavior tied to speed-sensor feedback
• Transmission warning lights related to sensor circuit faults
• Drivability concerns caused by inaccurate input-speed data
• Diagnostic trouble codes associated with the automatic transmission speed sensor circuit

Installation Notes

• Verify connector shape, terminal count, and harness length before installation.
• Inspect the transmission connector and wiring for corrosion, damage, or fluid intrusion.
• Confirm the sensor position matches the vehicle application: input.
• Clear stored codes and road test after installation to confirm proper signal operation.

Quality Assurance

NTK manufactures this sensor to OE-level standards and validates it through thermal shock, vibration, and OBD testing. The AU0029 is part of NTK’s full-line technical sensor coverage for import and domestic vehicles, including applications such as Buick Regal, Chevrolet Malibu, and GMC Acadia.
