Supply the speed signal your truck's transmission control depends on with this Dorman sensor, part number 904-7373 from the HD Solutions line. It is an automatic transmission speed sensor designed to fit and work like the original equipment unit. It fits many Freightliner trucks, among them the 2005-2006 Freightliner Argosy, 2017-2021 Freightliner 114SD and 2010-2021 Freightliner Cascadia (all engines). See the "Vehicles it fits" section for the full list.
- Direct replacement: Built to fit and function like the original equipment sensor. If the old sensor has failed, it helps restore the vehicle functions that depend on speed.
- Durable construction: Engineered to precise standards for accurate signal output, with a plastic housing.
- Easy installation: Designed to install with the original hardware and plug into the vehicle's existing wiring through a single tee-shaped connector with 4 blade terminals.
- Quality tested: Put through try-on validation and rigorous quality testing for a quality fit.
The sensor reads transmission speed and sends that signal to the vehicle's control module, which uses it for speed-dependent functions. Signs a transmission speed sensor may need replacing include erratic or harsh shifting and a lit warning light. Other faults can cause the same symptoms, so diagnose the cause before replacing the sensor.
The package contains 1 sensor. Mounting hardware and a wiring harness are not included, so consult the vehicle service information for the correct fasteners. Country of origin: Mexico.
