Standard Ignition TCS400 Automatic Transmission Control Solenoid

Automatic Transmission Shift Control Solenoid

Standard Ignition TCS400 is an automatic transmission control solenoid built for precise shift control in select Ford applications. It uses a stainless steel filter screen to help keep contamination away from valve components, along with a copper winding and OE-matched electrical characteristics for consistent operation.

Key Features

• Stainless steel filter screen helps protect valve components from contamination
• 100% copper winding supports positive valve actuation on command
• Resistance and inductance matched to OE specifications for proper fit, form, and function
• Precision-ground pintle moves freely to block or vent fluid pressure
• Male blade terminals with 2 + 3 terminal layout

Product Details

This Standard Ignition transmission solenoid is engineered for automatic transmission shift control where accurate fluid pressure routing is critical. The TCS400 is used in Ford E-350 Super Duty, Ford E-150, and Ford E-250 applications listed below, and it cross-references Dorman OE Solutions 924-971 for the same application. The TCS400 part number is also referenced by 9C2Z3Z719A and TCS943, with Standard Ignition TCS323 listed as another interchange.

• Contamination affecting valve body operation
• Electrical issues tied to worn solenoid windings or terminals
• Fluid pressure routing problems inside the transmission

Installation Notes and Tips

Verify the transmission code, connector style, and OE part number before installation. Inspect the valve body, wiring, and fluid condition during service so the new solenoid is not affected by existing contamination or electrical damage. Confirm the application matches your Ford E-350 Super Duty, E-150, or E-250 by year and transmission configuration.

Quality Assurance

Standard Ignition builds this solenoid with OE-matched resistance and inductance, a copper winding, and a precision-ground pintle to support consistent transmission control performance.
