Description: 4L80E 4L85E Transgo Shift Kit or Valve Body Repair kit for GM applications 1991-2009 This TransGo 4L80E SHIFT KIT® Valve Body Repair Kit fits 1991 to 2013 General Motors vehicles equipped with the 4L80E and 4L85E automatic transmission. Common complaints on this transmission soft 2-3, no upshifts, burnt direct clutch, broken hard parts due to high pressure, low pressure due to solenoid filter breakup as well as gear ratio and solenoid performance codes.The boost valve assembly is notorious for wear causing both low pressure as well as runaway boost pressure. With the low boost problem results in complaints of soft 2-3, direct clutch failure as well as the gear ratio and solenoid performance codes. On the other hand, the runaway boost pressure problem results in costly broken case, direct drum and piston.Features and benefits:This kit includes valve body, case and pump components and modifications designed to deliver increased durability while providing short smooth shifts. These changes work in concert with a slight increase in line pressure to greatly improve the overall durability and shift feel of the transmission. The included highly improved wide land self-cleaning design boost valve and bushing resists wear so that pressure rise keeps working properly. Lastly, the EPC boost pressure relief valve system provided helps prevent runaway boost pressure to stop case and valve body wall blow-out due to excess pressure.Corrects/Prevents/Reduces:High pressure parts breakageSoft 2-3 shiftBurnt direct clutchSlow 3-2 downshiftNo upshiftsHarsh 1-2 shiftLow pressure due to solenoid filter breakupCodes 39, 68, 85, 86, 87, P0731, P0732, P0733, P0734, P0751, P0756, P0894 and P1870Includes:USA-made hardened boost valve and bushingPressure regulator valve spacer, washer, springs and snap ringNew stronger 4th feed bolt and washer(2) Direct and reverse feed hole cup sealsRelief valve system plate, valve, spring, e-clip and drill bit(2) Accumulator valve springs, end plug and O-ringActuator filter tapered plug, O-ring, spring and end plug Hummer H1 1993-2005 V8 Gas 6.5L Diesel 4 Spd RWD 4X4Escalade, ESV, EXT 2006-2007 V8 4.8L 5.3L 4 Spd RWD AWDAvalanche 2001-2003 V8 8.1L 4 Spd RWD 4X4Express, Savana, 2500-3500 1996-2009 V8 4.8L 5.3L 5.7L 4 Spd RWD 4X4Express, Savana, 2500-3500 1996-2009 V8 6.0L 7.4L 4 Spd RWD 4X4Express, Savana, 2500-3500 2006-2010 V8 6.6L Diesel 4 Spd RWD 4X4Express, Savana, 3500 2002 V8 8.1L 4 Spd RWD 4X4Silverado,Sierra,1500-3500 1995-2007 V8 5.0L 5.7L 6.0L 6.5L 4 Spd RWD 4X4Silverado,Sierra,1500-3500 1995-2007 V8 6.6L Diesel 4 Spd RWD 4X4Suburban 1500-2500 1995-2007 V8 5.7L 6.0L 4 Spd RWD 4X4Suburban 1500-2500 1995-2007 V8 6.5L Diesel 4 Spd RWD 4X4Tahoe, Yukon 1995-2007 V8 5.7L 6.0L 4 Spd RWD 4x4Tahoe, Yukon 1995-2007 V8 6.5L Diesel 4 Spd RWD 4X4NPR Truck 1991-2004 V8 5.7L 4 Spd RWDNPR Truck 2005-2010 V8 6.0L Gas 4 Spd RWDXJS 1993-1996 L6 4.0L; V12 6.0L 4 Spd RWD Please be sure your Pan has 17 Bolt Holesfor your Transmission to be a 4L80E Parts ship daily from our distribution center.
