These components upgrade the transmission for maximum performance and durability by recalibrating pressures, recalibrating shift accumulation and includes improved parts for areas that commonly wear. It is suitable for any heavy duty application and a foundation for other upgrades when modifying the transmission for high performance uses. Shorter shifts which get progressively firmer with load. Faster pressure increase and higher overall pressure for greater clutch/band holding power. Improved high RPM pressure. Prevents worn accumulators and separator plate. Optional TCC on-off conversion prevents excess TCC pressure.APPLICATIONS Hummer (H3) (H3T) 2006-2010 L5 3.7L 4SPD RWD 4x4Hummer (H3) (H3T) 2008-2010 V8 5.3L 4SPD RWD 4x4Buick Roadmaster, Wagon 1994-1996 V8 5.7L 4SPD RWDRainier 2004-2007 L6 4.2L V8 5.3L 4SPD RWD AWDCadillac Fleetwood, Brougham 1994-1996 V8 4.9L 5.7L 4SPD RWDEscalade ESV EXT 1999-2007 V8 5.3L 5.7L 6.0L 4SPD RWD AWDCadillac Limo 1994-1996 V8 4.9L 5.7L 4SPD RWDChevrolet Astro Van Safari 1995-2007 V6 4.3L 4SPD RWD 4x4Avalanche 2001-2007 V8 5.3L 4SPD RWD 4x4Camaro 1994-2002 V6 3.4L 3.8L 4SPD RWDCamaro 1994-2002 V8 5.0L 5.7L 4SPD RWDCaprice, Wagon 1994-1996 V6 4.3L V8 5.0L 5.7L 4SPD RWDBlazer Jimmy 1994-2007 L4 2.2L V6 4.2L 4.3L 4SPD RWD 4x4Blazer Jimmy 1994-2007 V8 5.3L 4SPD RWD 4x4Envoy Trailblazer 1994-2009 L4 2.2L V6 4.2L 4.3L 4SPD RWD 4x4Envoy Trailblazer 1994-2009 V8 5.3L 4SPD RWD 4x4Colorado Canyon 2004-2006 L4 2.8L L5 3.5L 4SPD RWD 4x4Colorado Canyon 2007-2011 L4 2.9L L5 3.7L 4SPD RWD 4x4Corvette 1994-2005 V8 5.7L 6.0L 4SPD RWDExpress Savana 1500-2500 1996-2011 V6 4.3L V8 4.8L 5.3L 5.7L 4SPD RWD 4x4Impala 1994-1999 V8 5.7L 4SPD RWDS10 S15 Jimmy Sonoma 1994-2004 L4 2.5L V6 4.3L 4SPD RWD 4x4Silverado Sierra 1500-3500 1995-2010 V6 4.2L 4.3L 5.4L 5.7L 6.0L V8 4.8L 5.0L 5.3L 4SPD RWD 4x4Suburban 1500-2500 1994-2008 V8 4.8L 5.0L 5.3L 5.7L 4SPD RWD 4x4Tahoe Yukon 1994-2009 V8 4.8L 5.0L 5.3L 5.7L 4SPD RWD 4x4Isuzu Ascender 2003-2009 L6 4.2L V8 5.3L 5.4L 4SPD RWD 4x4Hombre 1997-2000 L4 2.2L V6 4.3L 4SPD RWD 4x4I280 2006 L4 2.8L 4SPD RWDI290 2007-2009 L4 2.9L 4SPD RWDI350 2006 L5 3.5L 4SPD RWD 4x4I370 2007-2009 L5 3.5L 4SPD RWD 4x4Oldsmobile Bravada 1994-2004 L6 4.2L V6 4.3L 4SPD RWD 4x4Pontiac Firebird 1994-2002 V6 3.4L 3.8L V8 5.7L 4SPD RWDGTO 2004-2007 V8 5.7L 6.0L 4SPD RWDSaab 9-7 9-7X 2005-2009 L6 4.2L V8 5.3L 4SPD AWDGTO 2004 V8 6.0L 4SPD RWD Parts ship daily from our distribution center.FREE SHIPPING on US Orders IN A HURRY - EXPEDITED SHIPPING IS AVAILABLE FOR THIS ITEMGOT QUESTIONS on your specific Year/Make/Model?Send us a messageThis item is packaged for Professional Transmission Shops.
