The 4L60E Valve Body for model years 2003-2008 has a Bosch Style EPC. Please see RED ARROW above for its location.



The 03-Up 4L60E uses a silver body Holley EPC solenoid with a molded connector (2). The valve body also has a full annular TCC with a bridge in the center of the square passage (3).

Problem: Some or all Solenoid Codes set when the vehicle is started.

Possible Cause #1: Check battery voltage during cranking. If the battery voltage drops below 10.5 volts, the battery needs charging, the cables need to be cleaned, or the battery needs to be replaced.

Possible Cause #2: The ignition switch may be faulty. Install a fused jumper wire between the positive battery cable and the "Trans" fuse in the fuse box on trucks. This will keep battery power to the solenoids during cranking if the ignition switch is bad. Start the engine and check for codes. If no codes are present with the jumper wire in place, then the ignition switch is bad.
