Is it possible to swap in a 4L80E for the stock 4L60E?
Just wondering if these two transmissions can be swapped? If so, what would be involved and what parts would I need to put a 4L80E into my 1997 Tahoe 4x4? Has anyone ever made this swap? I would like to make my Tahoe a better tow vehicle.

Not sure but I can tell you who will know.
Bone yards have substitution books, they tell what can fit where with what.
Most don't have a problem helping you out if they think they can sell you something, so just make like you want to buy one.

I think you need an ECU as well.
Why do you want a 4L60 the 4L80 is much stronger?Peter Smet

Shouldn't be a hard swap, even if the bellhousing doesn't match you should be able to swap that. But you would still need to either have the ECU updated, or replaced.
Why not see if you can get your hands on a wrecked 4x4 with an allison tranny.Patrick
