TransGo Performance Shift Kits® correct certain inherent design (or time caused) malfunctions, and at the same time, carefully revise the control system to supply more controlled oil to the shifting clutches and bands that activate the various gear ratios in the transmission. Additionally most kits increase the apply rate and holding ability of the Torque Converter Clutch (on models equipped with one). Most kits also increase lubrication flow for better cooling, converter feed, and of course lubrication to the gears, bearings, shafts, and bushings.
