Delphi SS11855 Automatic Transmission Speed Sensor

Delphi SS11855 Automatic Transmission Speed Sensor

Delphi SS11855 is an automatic transmission speed sensor built for output shaft and input shaft applications on select Ford, Lincoln, and Mercury vehicles. It uses a 3-terminal blade-style connection with a single rectangular male connector and female terminals for a direct-fit replacement approach.

Key Features

• Automatic transmission speed sensor for output shaft and input shaft applications
• Blade terminal type with 3 terminals
• 1 rectangular male connector with female terminals
• No wiring harness included
• Package contents: automatic transmission speed sensor and instruction sheet
• Delphi SS11855 cross-references Standard Ignition SC493 for the same application

Detailed Description

Delphi SS11855 is engineered for vehicles that rely on accurate transmission speed signal input for shifting and drivability control. It is a fitment-based replacement for select Ford Explorer, Ford Flex, Ford Fusion, Ford Edge, Ford Taurus, Ford Taurus X, Lincoln Continental, Lincoln MKT, Lincoln MKS, Lincoln MKZ, Lincoln MKX, and Mercury Sable applications. Delphi draws on OE heritage and decades of supplier experience to build aftermarket parts with the same application knowledge used in original equipment development.

What It Helps Address

• Erratic or delayed shifting caused by an inaccurate transmission speed signal
• Transmission warning lights related to speed sensor faults
• Harsh or inconsistent shift behavior tied to sensor signal loss
• Speedometer or drivability concerns linked to transmission output or input shaft sensing
• Diagnostic trouble codes associated with transmission speed sensor performance

Installation Notes and Tips

Verify the connector shape, terminal count, and shaft location before installation. This part uses a single rectangular connector and does not include a wiring harness or mounting hardware, so inspect the vehicle connector and surrounding transmission area before replacement. Confirm the application by year, make, model, and shaft position for Ford Edge, Ford Explorer, and Lincoln MKZ/MKX/MKS vehicles before ordering.

Quality Assurance

Delphi builds this replacement sensor using OE-focused engineering knowledge developed through long-term supplier experience with major automakers. That background supports consistent fitment and signal performance for transmission service on Ford, Lincoln, and Mercury applications.
