Fitment And Identification

Match this solenoid to the removed component by transmission model, screen color, connector style, physical configuration, and OEM reference number. This listing is for the two-red-screen EPC solenoid configuration.

The 4L30E transmission family was used across different vehicle and valve-body applications. Confirm the vehicle’s transmission identification and compare the original solenoid before ordering. Do not rely on model year alone to establish compatibility.

Service Information

The EPC solenoid controls hydraulic pressure in the transmission valve body. A failing or out-of-specification solenoid may be associated with harsh shifts, delayed engagement, slipping, shift flare, inconsistent shift quality, or transmission fault codes. These conditions may also be caused by worn valve-body components, damaged wiring, contaminated fluid, internal transmission wear, or electronic-control issues.

Diagnose the transmission before installing replacement parts. During service, inspect the valve body, harness, electrical connector, fluid condition, and related pressure-control components. Follow the manufacturer’s procedure for installation and fluid refill.

Use the manufacturer-specified ATF when completing service. Lubegard ATF Protectant may be used when compatible with the application and according to product directions; it does not replace needed transmission repair.
