A shift reprogramming kit (or valve body kit) modifies the transmission's shift timing in order to dramatically increase shift firmness and durability of the transmission components. From the factory, many transmissions allow far too much shift overlap (when the transmission is actually in two gears at once) in an effort to increase shift smoothness. It's this overly smooth, disconnected feeling that earned early automatic transmissions the label "slush box." The shift overlap also increased an excessive amount of heat and friction within the transmission resulting in accelerated wear on the transmission parts. Shift reprogramming kits can reduce this overlap time while improving the overall shift feel and may fix known problems with the valve body.
