Keep your automatic transmission's control module informed about fluid pressure with the Standard Ignition Automatic Transmission Pressure Switch Manifold PSA100. This transmission pressure switch assembly is a direct-fit OE replacement for many vehicles, including the 1999-2007 Chevrolet Silverado 1500, plus other Chevrolet, GMC, Buick and Cadillac models. See the "Vehicles it fits" section for the full list and engine details.
A pressure switch manifold uses a set of pressure-sensitive switches to report hydraulic pressure in the transmission's fluid circuits to the vehicle's control module. The module uses that signal to help determine the selected gear range and manage shifting.
- Direct-fit OE replacement: Designed for proper fit, form and function, with straightforward installation.
- Copper alloy conductors: Provide excellent electrical conductivity with low resistive losses.
- Robust design: High-grade material built to handle the demands of today's service professionals.
- Quality control: As a global manufacturer, Standard Ignition maintains quality control throughout the manufacturing process.
Signs this part may need replacing: Harsh, delayed or erratic shifting, or a check engine light with transmission-related trouble codes. These symptoms can have other causes, so diagnose the transmission before replacing parts. If a failed pressure switch manifold is the cause, PSA100 replaces it.
