hey guys my 47rh played out while towing about 30,000 miles ago I put a triple disk precision torque converter in with a transgo shift kit and all new cluthes. last week I noticed when the trans got warm it will not shift right for example when I turn on a side road no matter how slow I turned it would not shift out of 3rd until it reached 45 and shifted to OD if I stop at stop sign and take off it shifts from 1st to 3rd then OD. if the trans is cold or I use the shifter to from 1,2,D it does absolutely perfect. does anyone have any idea???
