Remanufactured 4L80E Pump Assembly – 2004-up GM Transmission (Core Charge Applies)

Working on a 4L80E transmission?

If you're rebuilding one from 2004 or newer, you might need a pump assembly.

This is a remanufactured unit from General Motors—fully disassembled, cleaned, inspected, and rebuilt with new parts where needed.

It's functionally equivalent to a brand new pump, and it's ready to install.

The interchange number is 34500EB, and it comes with a 6-month warranty.

Just a heads-up: there's a $100 core charge, so you'll need to send your old pump back.

But that's standard for reman parts.

If your 4L80E is slipping or has low line pressure, the pump might be the culprit.

Grab this reman unit and get your trans shifting right again.
