Restore Peak Performance to Your GM Vehicle
Is your 1998-1999 Oldsmobile Cutlass, Pontiac Grand Am, or Buick LeSabre suffering from erratic behavior? Issues like poor fuel economy, harsh shifting, a no-start condition, or a persistent Check Engine Light can often be traced back to a failing Powertrain Control Module (PCM). This module is the central computer of your vehicle, responsible for managing critical engine and transmission functions. When it fails, the entire driving experience is compromised.
This replacement PCM, part number 9357440, is the definitive solution to get your vehicle running reliably again. We take the guesswork out of the repair by pre-programming the unit specifically for your car using your Vehicle Identification Number (VIN). This ensures that all software is correct for your vehicle’s specific configuration and includes the latest updates available from General Motors. This plug-and-play approach simplifies installation and eliminates the need for expensive dealership programming.

Expert Pro Tip
Before replacing your PCM, always perform a thorough check of the vehicle’s battery, charging system, and all main power and ground connections to the module. A corroded ground wire or a weak battery can mimic PCM failure symptoms, leading to an unnecessary and costly replacement. A few minutes with a multimeter can save you hours of frustration.
