Keep your automatic transmission shifting on command with the Standard Ignition Automatic Transmission Control Solenoid, part number TCS40. It installs as a direct-fit replacement for the 1997-2001 Cadillac Catera — see the Buyer's Guide tab for engine-level application details. An electro-hydraulic control solenoid opens and closes on signals from the transmission control module to regulate the flow of transmission fluid, managing shift timing and hydraulic pressure inside the automatic transmission. When a failed control solenoid is the cause of harsh or delayed shifts, slipping, or a shift-related fault code, this unit replaces it.

  • Emission-component quality: produced by a global emission-components manufacturer with quality control maintained across the process, from componentry through finished product.
  • Broad coverage: part of one of the market's widest sensor and solenoid programs, so the right service part is on hand.
  • Direct-fit replacement: a straightforward swap for the listed application.

Because shift complaints can stem from other causes, diagnose the fault before replacing this solenoid. Signs it may need replacing include erratic or delayed engagement, slipping, or a stored solenoid-circuit trouble code.
