Standard Ignition PS-119 Automatic Transmission Spark Control Switch

Automatic Transmission Spark Control Switch for GM Classics

Standard Ignition PS-119 is an automatic transmission spark control switch built for precise oil pressure sensing in classic GM applications. It is engineered with a female connector, male blade terminals, and a 2-terminal layout for direct service replacement on supported Chevrolet and GMC vehicles.

Key Features

• Female connector with male blade terminals
• 2-terminal design for automatic transmission spark control service
• High-temperature polyimide film diaphragm construction
• Calibrated with laser etching for accurate pressure reading
• Built to withstand rapid pressure pulsations and demanding operating conditions
• 100% tested for activation, leak checking, and specification compliance

Detailed Description

Standard Ignition PS-119 is made for vehicles that rely on accurate transmission pressure input to manage spark control operation. The switch uses durable materials and a calibrated circuit design to help maintain consistent pressure response, while the diaphragm construction is selected for cycle durability and resistance to oil leakage. This part cross-references Standard Ignition TCS104 for the same application. It is a direct-fit service option for classic Chevrolet and GMC models, including Chevrolet Camaro, Chevrolet Nova, Chevrolet Corvette, and GMC Jimmy applications from the early 1970s.

Compatible With 1970-1971 Chevrolet Camaro, 1970-1972 Chevrolet Nova, and 1971-1972 GMC Jimmy applications, PS-119 also serves other GM platforms such as Chevrolet Caprice, Impala, Monte Carlo, Blazer, El Camino, Bel Air, and several GMC van and Suburban models. If you are searching for a Chevrolet Camaro transmission spark control switch or a GMC Jimmy automatic transmission pressure switch, this part number is a relevant match for the listed vehicles.

Common Problems This Part May Address

• Erratic spark control response tied to transmission pressure input
• Oil leakage at the switch body
• Intermittent electrical switching from worn internal components
• Pressure signal inconsistency during rapid pulsation conditions
• Failure of the original transmission spark control switch on listed GM vehicles

Installation Notes and Tips

Verify connector style, terminal count, and vehicle application before installation. PS-119 uses a female connector and male blade terminals, so the harness connection should match the original configuration. Confirm the transmission and engine application on the vehicle, especially when servicing 1970-1973 Chevrolet and GMC models with multiple drivetrain combinations.

Quality Assurance

Standard Ignition manufactures this switch with laser-calibrated circuitry, high-temperature diaphragm materials, and automated end-of-line testing. Each unit is checked for activation and leaks, then stressed to confirm specification compliance under demanding operating conditions.
