Keep your automatic transmission reading line pressure accurately with the Standard Ignition Automatic Transmission Pressure Switch Manifold (PSA101). It drops in as a direct-fit replacement for the 1993 Cadillac Allante, 1995-1999 Cadillac DeVille, 1995-1999 Cadillac Eldorado, and 1995-1999 Oldsmobile Aurora.

The pressure switch manifold houses the pressure switches that sense transmission fluid pressure across the hydraulic control circuits and report that information to the control module, which uses it to help manage shift timing and range detection.

  • What it does: Monitors automatic transmission fluid pressure and signals the control module for shift-timing and gear-range control.
  • Direct fit: Engineered to replace the original unit on the listed applications for a straightforward installation.
  • Signs it may need replacing: Erratic or harsh shifts, incorrect gear selection, or stored transmission pressure-switch fault codes — diagnose the cause first, and if a failed switch manifold is the source, this part replaces it.
