Sonnax shift improver performance packs combine innovative heavy-duty performance calibration for firmer shifts under load without sacrificing low-speed drivability. The precision components in these kits upgrade your transmission for maximum achievement and durability by recalibrating pressures, recalibrating shift accumulation, and including improved parts for areas that commonly wear. They are suitable for any heavy-duty application and are a critical foundation for other upgrades when modifying the transmission for high performance use. Sonnax shift improver performance packs additional facts and features: * Shorter shifts, which get progressively firmer with load * Faster pressure increase and higher overall pressure for greater clutch/band holding power * Three ultra-reliable, patented, billet pinless accumulator pistons * Unique 1-2 accumulator spring combination for shifts with character * Improved high rpm pressure * Third accumulator valve gets the 2-3 right the first time, every time * Consistent results, no guessing on calibration * Prevents worn accumulators and separator plate * Optional TCC on-off conversion prevents excess TCC pressure

Sonnax manual shift shafts help rebuilders use late model cores to rebuild into early model units. Sonnax manual shift shafts contain early model manual shift shafts that retrofit to a late model manual shaft detent lever, allowing the late model case and detent lever to be used in early models. These shafts offer a more economical solution than the OE manual shift shaft and detent lever kit, without the added cost for such additional components as the OE lever, pin, and shaft seal--parts rarely used during the rebuild. The manual shift shaft and fasteners have been yellow zinc plated for corrosion resistance to road salt and other environmental contaminates. The flange face of the nuts is serrated for better holding capacity.

TCI Maximizer rebuild kits also increase the torque capacity of the transmission to make towing or off-roading a breeze.
