Motorcraft DY1400 Turbine Shaft Speed Sensor (TSS) Automatic Transmission

The Motorcraft DY1400 is a genuine OEM Turbine Shaft Speed Sensor (TSS) designed for Ford automatic transmissions. This sensor monitors the rotational speed of the transmission's turbine shaft and relays that data to the vehicle's powertrain control module (PCM), enabling precise shift timing and accurate speedometer readings.

As a genuine Motorcraft part, the DY1400 is engineered to the exact same specifications as the original factory component, ensuring a direct OEM-grade fit and reliable long-term performance without modification or adaptation.

Key Features:

• Genuine OEM Motorcraft turbine shaft speed sensor (TSS)
• Monitors turbine shaft speed to support accurate transmission shift control
• Provides input data to the PCM for speedometer and shift point calibration
• Direct OE replacement — no cutting, splicing, or adaptation required
• Engineered and validated by Ford Motor Company
• Backed by the Motorcraft limited warranty

Symptoms of a failing turbine shaft speed sensor can include erratic shifting, harsh or delayed gear changes, incorrect speedometer readings, and transmission-related diagnostic trouble codes (DTCs). Replacing the sensor with a genuine Motorcraft unit restores factory-correct operation and helps prevent further driveline issues.
