I am on the 3rd 48RE rebuild (two since June 2008) in my 2005/QC.
It is important to keep on top of the band adjustments but in your case, 4 turns is quite a bit.. The band inside of the pan which handles Manual Low (First) and Reverse and the outer "Kickdown Band" are the two adjustments that you need to stay on top of; especially if you are drag racing, etc. The outer one is likely the more important of the two and doesn't require dropping the pan to adjust.

I went with a rigid band from an older 1970 (727 Torqueflite) which is the parent transmission to the 48RE. The 2005's factory band is a flimsy deal and has what amounts to a spray on coating of band material; they won't take much abuse. When they fail, the rivets chew into the drum almost immediately and make drum replacement a given. See the attached image of a brand new one.

We made a few mistakes but I think we have the right combination this time. Joe at Westminster has been a lot of help giving advice.

If yours suffers a total failure and there is band material in the pan, make sure you REPLACE the inline check valve near the front cooler. Also change out the 2 electrical pressure solenoids inside the pan (valve body area).

They aren't a bad transmission if you give them 1/2 a chance. They are very similar to the 48RE used in the diesels but there are enough internal and calibration differences to make them unique.

I'm no expert on these things. But lots of $$$ and downtime later, I know a few things that won't work! :D
The adjustments are easy to do yourself. Buy a decent inch pound torque wrench and follow the instructions in the service manual for the 48RE (gas engine section).

Ending on a good note it was just a few degrees above freezing here last night (Fall already). A 3900 foot D.A. instead of 5800+ makes a nice difference in power output. I was out at sea level last weekend (not in Orlando though) and I forgot what a huge difference it makes in power output. I envy you guys living at or near sea level.
We picked up nearly 3 pounds of boost in my buddies new Shelby just by dropping 4000 feet. That thing is a missile...11.8 @ 120 M.P.H. (drag radials) and 2 tanks at 27 M.P.G. during the trip-(a bit bigger gallon here in Canada). 270 miles on 45.46 liters= 27 m.p.g. with the a/c on... Cool or what !!??

My stock-build 48RE gave up shortly after the head and cam swap so I didn't really think it would be a good idea rebuilding the tranny to stock specs...
I hope this one lasts for a little while, the drag season here is nearly over.
