Auto Transmiss Parts 772014 Automatic Transmission Pressure Switch Manifold

The Auto Transmiss Parts 772014 is a direct-fit automatic transmission pressure switch manifold (PSM) designed to restore proper electronic shift control in compatible automatic transmission applications. This replacement part integrates multiple pressure switches into a single assembly, providing the transmission control system with accurate gear position and hydraulic circuit status information.

How It Works:

The pressure switch manifold mounts directly to the transmission valve body. Hydraulic fluid pressure is routed to the individual switches based on the position of the gear selector and the manual valve. The resulting digital logic signals at the electrical connector pins are read by the vehicle's Powertrain Control Module (PCM) or Transmission Control Module (TCM) to determine the current operating gear range and regulate shift solenoid operation, line pressure, and torque converter clutch engagement.

Key Features:

• Multi-switch assembly combining several pressure switches in one unit
• Direct replacement for failed or leaking OEM pressure switch manifolds
• Manufactured to meet or exceed original equipment specifications
• Restores accurate gear range detection and transmission control
• Designed for precise fit to OEM valve body mounting points

Also known as an auto trans pressure switch manifold or PSM, this part is a common service item on electronically controlled automatic transmissions. Cross-reference part number: JE-10.
