Standard Ignition SC129 Automatic Transmission Output Shaft Speed Sensor

Automatic Transmission Output Shaft Speed Sensor

Standard Ignition SC129 is an automatic transmission output shaft speed sensor built for direct-fit service on a wide range of GM and Saturn applications. It uses a female oval plug-in connector with a 2-pin male terminal layout and mounts on the transmission for straightforward replacement.

Key Features

• Automatic transmission output shaft speed sensor for transmission speed signal monitoring
• Female connector, oval shape, plug-in style
• 2-pin male terminal design for OE-style electrical connection
• Mounts on the transmission
• Standard Ignition SC129 for service replacement applications

Detailed Description

Standard Ignition SC129 is engineered for precise signal performance and long service life, with manufacturing control maintained from component selection through finished product. This sensor is used in transmission control systems that rely on output shaft speed data for shifting and drivability. It is a direct replacement choice for vehicles such as the Chevrolet HHR, Chevrolet Malibu, Pontiac G5, Pontiac G6, Saturn Vue, Saturn Aura, and related applications listed in the fitment data. This part cross-references Dorman - OE Solutions 917-620 and Delphi SS11807 for the same application.

What It Helps Resolve

• Erratic or delayed transmission shifting
• Speed signal loss from the transmission output shaft
• Transmission warning lights related to sensor input faults
• Harsh or inconsistent shift behavior caused by inaccurate speed data
• Drivability concerns tied to a failed output shaft speed sensor
