What Years 4L80E are Compatible?

I recently purchased a 2000 C3500 CCLB, I’m pretty sure the 4L80E in it is toast. What years would interchange with this year model?

97-02 will work. Earlier units have different cooler lines. Late units are weird.

So the electronics are plug and play also? And what do you mean by weird? Lol

I think its 05 and up that use a whole different controller. You will be safe sticking with a GMT400 unit 97+.

You're welcome! It was helpful for me when I was looking for a junkyard 80E for my red truck. There's a lot of other cool info on that site as well.
