I sent my ml torque converter in to precision to have it freshened up, a billet stator installed and to have the stall bumped up a little bit they said the converter looked perfect and everything was in spec. I've been having issues with the converter though in 5th gear if I'm in it hard it seems to start slipping when I get up around 95-100mph the truck revs wide open and quits pulling almost any ideas? The tranny was also freshened up about 1500 miles ago I'm not getting any codes at all any ideas?
