I'm looking for a 4L80E for my new project. I'd like a good used unit or a core that I can rebuild. Preferably early 2000s vintage to match the 5.3 I'm going to bolt to it. Happy to pay cash, or I have a 4L60E that came complete with the 5.3 and is supposed to be good, with a stock truck converter; I'd throw this into a trade with cash if anybody wants it.
Just trying to learn, are all 4L80E the same or at least interchange ?
and if you are getting a junkyard one , what parts do you need to also pull that goes with the trans you pull ? Is there a matching control box etc ?
I have a 2005 Van with a 4.8 and 4L80E , its still OK , but you never know :)
Thanks for the info
There are differences in model years, most of them broadly interchange (2wd and 4wd have differences).
The GM ECM controls the trans, Holley and other aftermarket ECMs will also control it. In the case of my harness and ECM that were intended for a 4L60E, there are some wiring plug differences at the trans that I'll have to change, as well as reprogramming the ECM to match.

If you need help in the yard I'm willing.
