img{max-width:100%} 4T65E Transmission Sonnax 3-4 Accumulator PistonIncludes:1 PistonDescription:It is common to have poor 3-4 shifts, no 4th gear or a burned 4th clutch in 4T65E units. This can be caused by excessive wear at the 3-4 accumulator piston pin bore, which allows 4th clutch oil to exhaust and can result in harsh 4th, no 4th gear or a burned 4th clutch. Pin bore wear also reduces 3rd clutch pressure during 3-4 shift. The 4th shift quality depends on the condition of the piston and accumulator valves. If the 4th accumulator piston siezes, the 4th shift will be very hard. This piston restores accumulator pressure and eliminates cross leaks.Features:Piston is manufactured from high grade billet aluminum to prevent wearTight tolerances and surface finish restore proper clearancesLine boost valve is no longer than the OE valve to increase wear surface areaPiston accepts OE or standard replacement D-Ring APPLICATIONSAllure 2005-2008 V6 3.6L 3.8L 4 Spd FWDCentury 2000-2005 V6 3.1L 4 Spd FWDLaCrosse 2005-2009 V6 3.6L 3.8L; V8 5.3L 4 Spd FWDLeSabre 1998-2004 V6 3.8L 4 Spd FWDLucerne 2006-2011 V6 3.8L 3.9L 4 Spd FWDPark Avenue, Ultra 1997-2005 V6 3.8L 3.8L SC 4 Spd FWDRegal 1997-2004 V6 3.8L 3.8L SC 4 Spd FWDRendezvous 2002-2007 V6 3.4L 3.5L 3.6L 4 Spd FWD AWDRiviera 1997-1999 V6 3.8L 4 Spd FWDTerraza 2005-2007 V6 3.5L 3.9L 4 Spd FWD AWDImpala 2000-2006 V6 3.4L 3.8L 4 Spd FWDImpala 2000-2006 V6 3.8L W S.C. 4 Spd FWDImpala 2006-2011 V6 3.5L 3.9L; V8 5.3L 4 Spd FWDMalibu 2006-2007 V6 3.9L 4 Spd FWDMonte Carlo 1997-2005 V6 3.4L 3.8L 4 Spd FWDMonte Carlo 1997-2005 V6 3.8L W S.C. 4 Spd FWDMonte Carlo 2006-2007 V6 3.5L 3.9L; V8 5.3L 4 Spd FWDUplander 2005-2008 V6 3.5L 3.9L 4 Spd FWD AWDVenture Van ,APV 1999-2005 V6 3.4L 4 Spd FWD AWDAurora 2001-2002 V6 3.5L 4 Spd FWDIntrique 1998-2002 V6 3.5L 3.8L 4 Spd FWDSilhouette 1999-2004 V6 3.4L 4 Spd FWDAztek 2001-2006 V6 3.4L 4 Spd FWD AWDBonneville 1997-2006 V6 3.8L 4 Spd FWDBonneville 1997-2006 V6 3.8L W S.C. 4 Spd FWDGrand Prix 1997 V6 3.8L W S.C. 4 Spd FWDGrand Prix 1998-2007 V6 3.1L 3.8L 4 Spd FWDGrand Prix 1998-2007 V6 3.8L W S.C. 4 Spd FWDGrand Prix 2005-2008 V8 5.3L 4 Spd FWDG6 2005-2009 V6 3.9L 4 Spd FWDMontana SV6 2005-2008 V6 3.5L 3.9L 4 Spd FWD AWDRelay 2005-2007 V6 3.5L 3.9L 4 Spd FWD AWDS80 1999-2004 L5 2.5L 4 Spd FWDXC90 2003-2006 L5 2.5L 4 Spd FWD¬†¬†Parts ship daily from our distribution center.FREE SHIPPING on US Orders GOT QUESTIONS on your specific Year/Make/Model?¬† Send us a message¬†√ā¬ŅHabla espa√ɬĪol?
