ATP Parts JE-9 Automatic Transmission Pressure Switch Manifold

Automatic Transmission Pressure Switch Manifold

ATP Parts JE-9 is an automatic transmission pressure switch manifold for GM and related applications that use manifold pressure logic to report gear range to the vehicle control system. It routes hydraulic pressure to the switch assembly based on selector position and manual valve position, helping the PCM or TCM read the transmission state correctly.

Key Features

• Automatic transmission pressure switch manifold for electronic gear-range signaling
• Uses fluid pressure to activate the switch logic at the electrical pins
• Supports transmission range input for PCM and TCM operation
• Fits a wide range of Chevrolet, GMC, Cadillac, Buick, Pontiac, Hummer, Isuzu, Saab, and Oldsmobile applications
• ATP Parts JE-9 cross-references Dorman - HELP 74442 for the same application

Product Details

The ATP Parts JE-9 pressure switch manifold is built for transmissions that rely on manifold pressure to communicate operating range. In vehicles such as the Chevrolet Silverado 1500, GMC Sierra 1500, and Chevrolet Tahoe, the switch assembly helps translate hydraulic pressure into the electrical signals used by the control module. This makes it a direct-fit service part for many 1993-2008 GM truck, SUV, van, and performance applications.

Compatible With 1993-2008 Chevrolet Silverado 1500, 1995-2008 Chevrolet Tahoe, and 1999-2008 GMC Sierra 1500 applications, this manifold pressure switch assembly is also listed for models including the Chevrolet Colorado, GMC Envoy, and Cadillac Escalade. Part number JE-9 is also referenced by BBB Industries 16826 and TechSmart M14001.

Common Problems It Can Address

• Incorrect gear-range signal to the transmission control module
• Transmission warning lights related to pressure switch input
• Delayed or inconsistent range recognition during shifting
• Fault codes tied to manifold pressure switch performance
• Driveability issues caused by inaccurate selector-position reporting

Installation Notes and Tips

Verify transmission type and application notes before installation. Some listings specify 4L60-E, THM700-R4/4L60/MD8 coverage, so confirm the exact transmission family on the vehicle. Inspect the connector, wiring, and fluid condition during service to help ensure the new manifold switch assembly can report range information accurately.

Quality Assurance

ATP Parts supplies transmission hard parts for service applications that depend on accurate hydraulic-to-electrical signal conversion. JE-9 is cataloged for broad OE-style fitment across multiple GM platforms and related badge-engineered vehicles.
