most likely 4l60e on the 00-01, 00 was a changeover year and 02 they made some more changes, call your local dealer's parts department and give them last 8 of your vin and they can verify

4l80 only came in 2500 series suvs. The lower bellhousing can be unbolted on the 4l80 so it's ez to tell them apart. You have a 4160.

I’ve heard that some of the 2002 year Denali xls on a 1500 chassis came with a 4L80E trans. I had a client with a 2002 xl Denali that I think had a 4L80 in it. It was pretty awesome. I’d love to have the 4L80 trans in my 2006. Would be an awesome rig haha. I thought all the Denali trucks with the 6.0L had the 4L65E trans?! That’s what I was told. Lol.

Away!
I'm under the same impression on the 4l65e.

The 4L65e came into being in 2001 however I would bet yours is the 4L60e.
Outside they don't really have any cosmetic cues that I am aware of. Your VIN would help as would the code on your glove box door. I believe the M30 code is the 4L60e. I'll have to look further for a code for the heavier duty 4L65e.
