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

TCI Trans-Scat valve body kits offer you two options: you can either have good, solid shifting that's well suited to towing, or you can have competition-style shifting. These kits eliminate slippage and lag, improve fuel economy, extend clutch life, and really improve the 2nd and 3rd gear shifts. In addition to delivering crisper shifting, they allow you to downshift on demand, and most will allow you to hold first gear for extended periods, such as when climbing long hills while towing. All kits give you the full range of normal automatic functions when in "drive."

B&M's ShiftPlus electronic shift improvers use vacuums or electronics to improve the characteristics of your transmission, and let you change settings as you drive. Great for performance, towing, and RV use, these shift improvers recalibrate your transmission in one of two ways: Vacuum-style transmissions, such as a GM 4T60E, simply recalibrate the hydraulic system through the modulator circuit to provide firmer, more positive shifts; electronically controlled transmissions, such as a Ford AODE, recalibrate the transmission's hydraulic system electronically to give you a firmer, quicker shift, for better performance and longer transmission life. A flip of the switch allows the transmission to operate in the original factory mode at level 1 (firmer than factory) or level 2 (much firmer than factory). Either type installs in minutes with a few simple hand tools, without removing the pan.
