What It Helps Address

• Erratic or delayed transmission shifting
• Transmission speed signal faults
• Check engine lights related to speed sensor performance
• Harsh or inconsistent gear changes
• Loss of transmission input speed data

Installation Notes and Tips

Verify the connector style, terminal count, and sensor position before installation. This part is listed for input and output applications depending on vehicle fitment, so confirm the exact location on the vehicle before replacement. Inspect the connector and harness for corrosion, bent terminals, or damaged wiring before installing the new sensor. For best results, clear diagnostic trouble codes after installation and confirm proper transmission operation during a road test.

Quality Assurance

NTK manufactures this sensor to OE-level specifications and subjects it to thermal shock, vibration, and OBD verification testing. That OE-driven process supports consistent performance across the listed Ford, Lincoln, and Mercury applications, including Ford F-150, Ford E-150, and Lincoln Town Car fitments. Part number AU0173 is part of NTK’s technical sensor lineup for aftermarket coverage.
