• NTK AU0140 is backed by OE-focused sensor engineering.
• Compatible with multiple Ford, Lincoln, and Mercury applications.

Detailed Description

NTK AU0140 is part of the NTK Automatic Transmission Speed Sensor line and is designed for vehicles that rely on precise transmission speed data for shifting and control. This sensor is used across Ford Mustang, Ford Explorer, Ford Explorer Sport Trac, Mercury Mountaineer, Lincoln LS, Ford Thunderbird, and Lincoln Aviator applications, with fitment covering both input and output positions where listed. The AU0140 part number appears in OE-style replacement searches for these applications, and the sensor construction reflects NTK’s OE experience and technical sensor focus.

NTK builds its technical sensors using testing that includes thermal shock, vibration, and OBD verification. That approach supports consistent signal performance and OE-level specification alignment for drivers servicing transmission sensor faults on Ford, Lincoln, and Mercury platforms. If you are replacing a failed transmission speed sensor, AU0140 provides a fitment-specific solution for the listed applications.

What It Is Used For

• Restoring transmission speed signal accuracy.
• Addressing harsh, delayed, or inconsistent shifting caused by sensor faults.
• Replacing a damaged or electrically failed speed sensor.
• Resolving transmission-related diagnostic trouble codes tied to speed input or output signals.
• Servicing OE-style transmission sensor applications on Ford, Lincoln, and Mercury vehicles.

Installation Notes and Tips

Confirm the vehicle year, make, model, and sensor position before ordering AU0140. Verify the connector shape, terminal count, and mounting location against the original part to ensure proper electrical and mechanical match. This part does not include mounting hardware or a wiring harness.
