4L80E Trans Pump Questions
Good Morning,
I am in the middle of a rebuild of my 4L80E on a 2005 Chevy Express van. I have been following a tutorial for the complete teardown and subsequent rebuilding of it. I have come to a spot where I am dealing with rebuilding the pump on it. I have purchased a reman pump, but had to remove all the valves from my old one. I have confirmed with the place I purchased it from that it is the correct part number (34500ED) for my model year transmission by confirming the cast numbers on both halves of the pump assembly. What I need is a place to purchase the valves that are inside the pump, TCC enabling valve, TCC Valve, and the converter limit valve. Can anyone help me out with where I can purchase these as the ones out of my old pump do not fit properly, thanks in advance for any help.
