Scoring is caused by repeated oscillation of the accumulator piston within the bore during normal operation. Once this bore is damaged the case must be scrapped.

The kit's piston is compatible with all OE accumulator springs.Sleeve is manufactured from wear-resistant aluminumRequires no machining of the transmission caseContentsRepair SleevePistonO-Ring FluorocarbonAccumulator PinApplications4L60EHummer (H3) (H3T) 2006-2010 V8 5.3LBuick Rainer 2004-2007 L6 4.2L V8 5.3LRoadmaster, Wagon 1994-1996 V8 5.7LCadillac Escalade, ESV, EXT 1999-2007 V8 5.3L 5.7L 6.0LFleetwood, Brougham 1993-1-996 V8 4.9L 5.7LLimo 1993-1996 V8 4.9L 5.7LChevrolet Astro Van, GMC Safari 1995-2007 V6 4.3LAvalanche 2001-2009 V8 5.3LBlazer, Jimmy 1993-2007 V6 4.3L V8 5.3LEnvoy, Trailblazer 1993-2009 L4 2.2L L6 4.2L V6 4.3L V8 5.3LCamaro 1994-2002 V8 5.7LCaprice, Wagon 1993-1996 V6 4.3L V8 5.0L 5.7LColorado, Canyon 2004-2011 L4 2.8L L5 3.5L L4 2.9L L5 3.7L V8 5.3LExpress, Savana 1996-2011 V6 4.3L V8 4.8L 5.3L 5.7LImpala 1994-1999 V8 5.7LS10, S15, Jimmy, Sonoma 1993-2004 L4 2.2L 2.5L V6 4.3LSilverado, Sierra 1500-3500 1995-2010 V6 4.2L V6 4.3L V8 4.8L 5.0L 5.3L V6 5.4L 5.7L 6.0LSuburban 1500-2500 1993-2008 V8 4.8L 5.L 5.3L 5.7LTahoe, Yukon 1993-2009 V8 4.8L 5.0L 5.3L 5.7LIsuzu Ascender 2003-2009 L6 4.2L V8 5.3L 5.4LHombre 1997-2000 L4 2.2L V6 4.3Li280 2006 L4 2.8Li290 2007 L4 2.9Li350 2006 L5 3.5Li370 2007-2009 L5 3.5LOldsmobile Bravada 1993-2004 L6 4.2L V6 4.3LPontiac Firebird 1994-2002 V6 3.4L 3.8L V8 5.7LGTO 2004 V8 5.7LSAAB 9-7, 9-7X 2005-2009 L6 4.2L V8 5.3L 4L65EHummer (H2)(H2 SUT) 2004-2007 V8 6.0L 4SPD RWD 4X4Buick Rainer 2004-2007 L6 4.2L V8 5.3L 4SPD RWD AWDChevrolet Express, GMC Savana 1996-2011 V8 4.8L 5.3L 5.7L 4SPD RWD 4X4Blazer, Jimmy 1992-2007 V6 4.3L V8 5.3L 4SPD RWD 4X4Envoy, Trailblazer 1992-2009 V6 4.3L V8 5.3L 4SPD RWD 4X4SSR 2003-2007 L6 4.2L V8 5.3L 6.0L 4SPD RWD Parts ship daily from our distribution center.FREE SHIPPING on US Orders GOT QUESTIONS on your specific Year/Make/Model?
