4L80E 7-Piece Master Solenoid Kit with Internal Wire Harness and Filter (2004-On)

When a 4L80E starts throwing shift codes, hanging in gear, or losing converter lockup, the solenoids and the internal wire harness are almost always where the trouble lives. Replacing one piece at a time is how you end up back under the truck a month later chasing the next failure. This 7-piece master kit refreshes the whole electrical package in one job, so the transmission goes back together sorted.

The set covers the EPC pressure control solenoid that sets line pressure, the A and B shift solenoids, and the TCC lockup solenoid, along with the internal wire harness that ties them to the case connector and a fresh filter. The pieces cross to GM OEM numbers 24248892 (EPC), 24230288 and 24230289 (shift), 24210864 (TCC), and 24200161 (harness). Everything is new, not rebuilt, so you are not gambling the job on tired parts.

This is the 2004-on version, so it fits the later 4L80E and 4L85E units found across the GM truck, van, and SUV lineup. Confirm your year before ordering, since the connector and harness changed at the 2004 split. Lay it out against the valve body, swap the electrical package as a set, and give the unit a clean bill of health instead of a partial fix. Ships from the USA.
