Delphi SS11871 Automatic Transmission Speed Sensor

Automatic Transmission Speed Sensor for Ford and Mercury

The Delphi SS11871 automatic transmission speed sensor is built for output shaft applications on select Ford and Mercury vehicles. It uses a round, 1-connector design with pin terminals and a female terminal layout to support accurate transmission speed signal reporting.

Key Features

• Automatic transmission speed sensor for output shaft applications
• Round connector with 1 connector and 2 terminals
• Pin terminal type with female terminal gender
• Male connector gender for direct replacement-style service
• Package contents include the sensor and instruction sheet
• Delphi SS11871 part number for OE-style transmission sensor replacement

Detailed Description

Delphi brings OE heritage and decades of supplier experience to the SS11871 automatic transmission speed sensor. Built for transmission speed monitoring at the output shaft, this sensor is used on 1999-2000 Ford Windstar and 2000-2003 Ford Taurus and Mercury Sable applications. The SS11871 is a practical replacement choice when you need a transmission speed signal sensor that matches the original connector style and terminal configuration.

This part cross-references Standard Ignition SC458 for the same application. The Delphi SS11871 is also referenced by interchange numbers SN7393, VSS993, and XF2Z 7H103-AA.

What It Helps Address

• Erratic or missing vehicle speed signal from the transmission
• Transmission shifting concerns related to output shaft speed input
• Speedometer operation issues tied to transmission sensor signal loss
• Diagnostic trouble codes associated with transmission speed sensor performance
• Replacement needs after sensor wear, contamination, or electrical failure

Installation Notes and Tips

Verify the connector shape, terminal count, and output shaft location before installation. This Delphi SS11871 uses a round connector, 1 connector, and 2 terminals, so matching the original sensor configuration is important for proper fitment. Mounting hardware and wiring harness are not included, so reuse existing components only if they are in serviceable condition. Confirm vehicle application by year, make, model, and transmission position before ordering.

Quality Assurance

Delphi builds aftermarket parts using OE experience and supplier knowledge developed through service to major automakers. The SS11871 reflects that OE-based engineering approach for transmission sensor replacement on compatible Ford and Mercury applications.
