Lagging when shifting?? (727 auto, w/ full manual valve body)

......U guys have to give more info.......we can only guess with having 1/2 or less info.....So u have the Trans Go -2 in it then?....do u have the kick down/throttle pressure linkages/cable on it and set right?...shifting too soon is a misadjusted kd linkage/cable...or somethings likely not clearanced right, in that case tranny may/will need to come back out.........kim......
