I have 125,000 miles on my 97 2500HD V10 with the 47RE. No problems whatsoever. Towed boats, fifthwheel, jet skis (not at the same time)and had a slide in camper. Always towed in So Cal and AZ deserts during the summer.
Changed transmission fluid once a year.
My 97 shifts smoother than my brand new 600. Although I only have 1500 miles on it.
