Delphi SS11856 Automatic Transmission Speed Sensor

Automatic Transmission Speed Sensor for Ford and Lincoln

Delphi SS11856 is an automatic transmission speed sensor built for input shaft applications on a range of Ford and Lincoln vehicles. It uses a 3-terminal blade-style design with a single rectangular male connector and female terminals for a direct electrical connection.

Built from Delphi’s OE experience, this transmission speed sensor supports accurate transmission speed signal reporting for drivability and shift control on applications such as the Ford Explorer, Ford Flex, Ford Fusion, Ford Edge, and Lincoln MKT.

Key Features

• Automatic transmission speed sensor for input shaft and select output shaft applications
• Delphi SS11856 part number for OE-style replacement identification
• 1 rectangular connector with male connector gender and female terminals
• 3-terminal blade connection for secure electrical interface
• Package includes the automatic transmission speed sensor and instruction sheet
• Cross-references Standard Ignition SC501 for the same application

Detailed Description

The Delphi SS11856 transmission speed sensor is engineered for vehicles that rely on precise transmission input shaft speed feedback to help the control system manage shifting and transmission operation. Delphi draws on OE heritage and supplier experience with major automakers, and that background is reflected in the design and electrical layout of this replacement sensor. If you are servicing a Ford Explorer, Ford Flex, Ford Fusion, Ford Edge, or Lincoln MKT, SS11856 is a direct part number to verify against your original sensor.

This part cross-references Standard Ignition SC501 for the same application. It also interchanges with AA5Z 7M101-B, SN8203, and VSS1035.

What It Helps Address

• Erratic or delayed transmission shift behavior
• Transmission speed signal loss or inconsistent sensor readings
• Illuminated transmission-related warning lights tied to speed sensor faults
• Harsh, unstable, or incorrect shift timing caused by input shaft sensor issues
• Diagnostic trouble codes related to transmission speed sensor performance
