Mine has never been out of the truck, almost 300,000 miles, the last
50K have been behind a turbo engine, at about 150 HP, and pulling
33" tires, I drove it to Moab, and have taken plenty of long trips, it's
as solid as it can be.
I keep putting fluid in it because it always has lost fluid, not a drip, but
a mist while driving, so keep it full, mine likes to be over full by about 1
quart, I don't know why, but it seems to happier when I'm on steep
stuff off road.
I did add a slick 50 auto trans treatment at 70K miles when I first changed
the fluid, and I think I would add a Lucas trans treatment just for good measure
