img{max-width:100%} 4L60E 4L65E 4L70E Transmission Regulator & Isolator Valve Kit Sonnax 77754-04KAny application, including '98-later EC3 unitsSevere wear of the TCC regulator valve bore caused by oscillation of the OE valve allows regulated converter apply pressure to exhaust. This is a primary cause for TCC-related slip code P1870 and overheated converters. Exhausting apply pressure also diminishes line pressure, which can result in burnt clutches. Excess wear at the isolator valve bore reduces TCC apply pressure. Reconditioning the bore and installing Sonnax TCC regulator and isolator valve kit 77754-04K restores normal TCC operation by restablishing the hydraulic integrity of this circuit.Sleeve manufactured from highly wear-resistant aluminumHardcoat anodized aluminum regulator valve combats premature wearIsolator valve lengthened to operate in unworn portions of the boreAnnular grooves help center valves in bore to reduce future side-load wearContentsIsolator ValveSpringRegulator ValveRegulator Sleeve APPLICATIONSHummer (H3)(H3T) 2006-2010 L5 3.7L V8 5.3LBuick Rainer 2004-2007 L6 4.2L V8 5.3LCadillac Escalade, ESV, EXT 1999-2007 V8 5.3L 5.7L 6.0LFleetwood, Brougham 1993-1996 V8 4.9L 5.7LLimo 1993-1996 V8 4.9L 5.7LChevrolet Asto Van, Safari 1995-2007 V6 4.3LAvalanche 2001-2009 V8 5.3LBlazer, Jimmy 1993-2007 L4 2.2L L6 4.2L V6 4.3L V8 5.3LEnvoy, Trailblazer 1993-2009 L4 2.2L L6 4.2L V6 4.3L V8 5.3LCamaro 1994-2002 V6 3.4L 3.8L 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 1500-2500 1996-2011 V6 4.3L V8 4.8L 5.3L 5.7LS10, S15, Jimmy, Sonoma 1993-2004 L4 .4L 2.5L V6 4.3LSilverado, Sierra 1500-3500 1995-2010 V6 4.2L V6 4.3L V8 4.8L 5.0L 5.L V6 5.4L 5.7L 6.0LTahoe, 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 2007-2009 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 Parts ship daily from our distribution center.FREE SHIPPING on US OrdersIn a Hurry - this item is available for expedited shippingGOT QUESTIONS on your specific Year/Make/Model?
