Ok i swapped 4l80e into my truck from a truck with a bad frame that sat for about 3 years and was fine prior to sitting. changed the filter and fluid dropping the pan not a complete flush and fill. when i get on it to downshift sometimes it doesnt want to shift back to OD. is there anything i can do for this short of a rebuild? any additives? 98 k2500
