Like you guys, I ran into the same problem with my 97 GC with the 44RE. I have both a Chiltons and a Haynes for it and both of them had different numbers for the band adjustments. I called the service manager at the dealer and he transferred my to their transmission guy and I asked him what he used. He had numbers for the front and rear band adjustments that were about 1/2 of the amounts listed in the Chiltons and Haynes. I used his numbers for the adjustments, changed the filter at the same time, put a drain plug in the pan and put it back together. I only did that once, and I don't have the mileage in front of me at the moment, but I think it was somewhere around 75-100K. I have over 250K on it now, and it's still doing o.k. My experience with automatics has taught me that the greater the number of turns out from snug, the slower and softer the shift happens because the piston that is tightening the band has to move further in the bore in the valve body. I think, but don't have hard evidence to back it up, that this slow engagement causes more wear to the bands and friction discs in the clutch packs. After adjusting per the dealer mechanic's specs , mine did shift faster and firmer. Just my 2 cents. If anybody wants those band adjustment specs, I can post them.
Found the specs I used: Front band - 1 1/2 turns out. Rear band - 1 3/4 turns out
