Keep your automatic transmission shifting on schedule with the Standard Ignition Automatic Transmission Pressure Switch Manifold (PSA102). It installs as a direct-fit replacement across a broad range of GM trucks, vans and SUVs, including the 1991-1994 Chevrolet Blazer, 1991-1999 Chevrolet C1500, 1995-2007 Chevrolet Tahoe, 1999-2000 and 2002-2006 Cadillac Escalade, and 1996-2009 Chevrolet Express 1500/2500/3500 and GMC Savana — see the Buyer's Guide tab for the full list.

This pressure switch manifold houses the transmission's pressure switches, which monitor hydraulic fluid pressure inside the automatic transmission and report it to the control module so shifts are commanded at the right time. Over time these switches can fail electrically or leak. If a faulty pressure switch manifold is the cause of erratic shifting, harsh engagement, or stored transmission trouble codes, this assembly replaces the original unit — diagnose the cause before replacing.

  • OE-level performance: built to meet or exceed OE performance so the job gets done right the first time.
  • Direct-fit replacement: engineered to drop in for straightforward installation on the listed applications.
  • Complete assembly: supplied as a pressure switch manifold assembly.
  • Country of origin: Taiwan.
