Hello, just rebuilt 5R55W due to grenaded O.D. planet. Replaced O.D. planet, sun gear, bearing, clutches, drum and convertor. Trans shifts okay 1,2,3 but 3 to 4 is harsh. I rechecked band adjustment of 120 inch lbs and back off 2 turns, I also tried different variations; loosening and tightening to no avail. I also replaced the O.D. servo, again to no avail. O.D. light is flashing rapidly but lock-up works fine...any help would be greatly appreciated, John.
