4T65E Transmission TCC Apply Valve Kit with Seal Sonnax 84754-43K

img{max-width:100%} 4T65E Transmission TCC Apply Valve Kit with Seal Sonnax 84754-43KContinuous oscillation of the converter apply valve in the cast-aluminum bore causes bore wear, particularly at the TCC signal valve spool closest to the solenoid. Wear in this area allows TCC signal oil to leak, which inhibits the valve from stroking to the lockup position. Due to the valve body casting design and oil flow, this valve is also subject to extreme side loading, which increases the wear rate. Early OE versions of this valve were made from non-anodized aluminum, and show significant wear marks.Hardcoat anodized aluminum valve with an expandable PTFE seal on the TCC signal valve spool provides a positive seal to ensure proper stroking of the valve.The most inward Sonnax valve spool is almost 2.5 times longer then the OE spool, creating more valve-to-bore sealing area.Greater sealing area combined with annular grooves allows the valve to stay centered in the bore and prevents side loading.An extra PTFE seal and a new spring to fit within the valve spring pocket are included in the kit.A replacement O-ring has been included for the OE end plug, to be used after inspecting the TCC regulated apply valve.NoteAlways inspect the TCC regulated apply valve for wear. The O-ring in this kit should be used to replace the original end plug O-ring after inspection. Worn valves or bores can be repaired using the Sonnax TCC regulated apply valve and sleeve kit 84754-34K.ContentsValvePTFE Seals (2) 1 extraSpringO-RingAPPLICATIONSAllure 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 ¿Habla español?
