Keep your automatic transmission’s hydraulic circuits responding on command with the Pioneer Transmission Control Solenoid, part number 771031. It is an exact-fit replacement for a wide range of Chevrolet, GMC, Cadillac, Pontiac and Isuzu trucks, vans, SUVs and cars, including the 1996-2004 Chevrolet Corvette, 1996-2002 Chevrolet S10, 1996-2002 GMC Yukon, 1996-2002 Pontiac Firebird and 1999-2002 Chevrolet Silverado 1500.
An automatic transmission control solenoid is an electrically operated valve. The vehicle’s control module energizes it to direct transmission fluid through the transmission’s hydraulic passages, helping the transmission carry out the commands it receives from the vehicle’s computer.
- Exact fit: Pioneer builds its transmission components as exact-fit replacement parts, made without compromise.
- Electronically controlled: Responds to signals from the vehicle’s control module to route transmission fluid.
- Broad coverage: Listed for dozens of Cadillac, Chevrolet, GMC, Isuzu and Pontiac applications.
Signs a transmission control solenoid may need replacing include harsh, delayed or erratic shifts, a transmission that won’t shift or stays in one gear, and an illuminated check engine light. Wiring, fluid condition or internal transmission problems can cause the same symptoms, so diagnose the cause before replacing. If a failed solenoid is responsible, this part replaces it.
Additional applications include the 1996-2002 Chevrolet Astro, 1996-2002 Chevrolet Express 1500, 1996-2002 GMC Safari and 1996-2000 Isuzu Hombre. See the Buyer’s Guide tab for the full list.
