A Faceplace Marketbook 4L80E has been acquired from a truck that had a 6.5 diesel with a cracked block. I was seriously considering a 6L80 swap like
@97Centurion did, but I keep seeing people with 6L80s commenting they wish they had the reliability of a 4L80. Also, I got the 4L80 for $400. The fluid looks decent-ish and he swore it was under a camper shell until last week, so it shouldn't have more than a teaspoon of water in the fluid.
So, school me on 4L80s. I know it's an earlier version because it has the trans cooler fittings closer together and no top bolt hole. Is the wiring receptacle the earlier or later version? I don't see a bolt-down for the plug, so I'm thinking it's a '94-96 transmission, and that's what he claimed. The receptacle is loose, so the pan needs to come off so I can reattach whatever retaining ring has come loose.
It needs a torque converter, a dipstick, a pan and filter, rear seal, and depending on the condition of the internal wiring harness I may buy a new harness from RockAuto. Anything else I should replace out-of-hand?
