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 hydraulic line pressure booster kits contain stronger pressure regulator springs and large ratio boost valves designed to work together, providing progressive pressure increases as driving conditions become more demanding. Their springs are approximately 10 percent stronger than OEM and more conservative in impact than other aftermarket kit springs. Large ratio boost valves provide higher pressure incrementally and when it's needed the most. The combination of these springs and valves in the Sonnax hydraulic line pressure booster kits gives you the best of both worlds--a modest pressure increase at the low-end, with a high-end pressure that's equal to or greater than that of other aftermarket kit springs.

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.

Transmission cases made in 1994 and 1995 have neutral safety switch mounting holes, but do not have the top mount shifter bracket holes. That's where these Sonnax shift cable mount brackets come into play, by allowing installation of the 1994 and 1995 transmissions or cases into 1996–97 vehicles that originally had case mounted shifter brackets. Additionally, if a late case has become damaged or has broken top mount bosses, these Sonnax shift cable mounting brackets can be used as an alternative to allow you to correctly mount the shifter cable and allow the reuse of the case.

Sonnax universal remanufactured valve bodies have been uniquely designed to fit a variety of '99-later Chrysler applications, regardless of OE checkball or solenoid configuration. The convenience of stocking one SKU number for various applications saves time, money and interchangeability confusion. The channel casting has been resurfaced to SAE recommended flatness and surface finish. The seasoned casting warpage is now eliminated, removing cross-leaks and manufacturing burrs that resulted in clutch distress and shift complaints. A new separator plate is also installed, along with gaskets, to seal the critical surfaces between the valve body and channel casting. Heavy-duty/high performance accumulator pistons with dual-guide seals are installed to prevent piston-to-bore scuffing and restore clutch pressures due to leakage. Patented Sonnax valves are installed to restore hydraulic pressures and eliminate shift complaints, trouble codes, converter concerns and overdrive clutch distress. Their patented accumulator cover plate—made from stronger, thicker material and secured with additional screws—is also installed to prevent flexing or breakage. To guarantee the highest level of operational performance, these remanufactured valve bodies are tested on state-of-the art equipment to verify that pressures match OE specification. Product notes: * One SKU fits all applications, saving time, money and confusion * Resurfaced OE channel casting eliminates warpage, burrs, and cross-leaks cost effectively * New separator plate and gaskets provide critical seal between cast surfaces * Patented Sonnax valves and pistons restore hydraulic integrity of circuits to eliminate shift complaints and clutch distress * Patented Sonnax accumulator cover plate stronger than OE to prevent flexing and breaking
