![]() ![]() 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. The included highly improved wide land self-cleaning design boost valve and bushing resists wear so that pressure rise keeps working properly. 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 TransGo 4L80E SHIFT KIT® Valve Body Repair Kit includes valve body, case and pump components and modifications designed to deliver increased durability while providing short smooth shifts. On the other hand, the runaway boost pressure problem results in costly broken case, direct drum and piston. 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. The boost valve assembly in these transmissions are notorious for wear causing both low pressure as well as runaway boost pressure. Step 1 Identify the Type Accum housing you are using (2nd or 3rd Type), then choose new spacer that matches your housing and install it with new small orange spring. The springs in this kit provide the tension needed to keep the clutches from applying in 1 st or 2 nd at high RPM as well as providing for a cleaner forced throttle 3-2 downshift by helping the 3-4 clutch release faster.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 the 4L80E and 4L85E automatic transmissions are soft 2-3 shifts, no upshifts, burnt direct clutch, broken hard parts (due to high pressure), and low pressure (due to solenoid filter breakup as well as gear ratio and solenoid performance codes). This 700-2&3 Reprogramming Kit fits 1982 to 1993 General Motors vehicles equipped with the 700R4/4L60 automatic transmission. This TransGo Reprogramming Kit provides full manual control for upshifting and downshifting 1 st through 4 th gear, there are no automatic shift functions retained. This TransGo clutch spring kit includes a new 3-4 orifice capsule to mitigate the checkball leak and also provides an additional exhaust for the trapped residual oil. Secondly the tension that OE springs provided was inadequate. Depending on the clutch stack up the OE load release springs could be rendered non-functional. Many techs prefer to install additional frictions in the 3-4 clutch. The GM load release springs are a step in the right direction however they have their limitations. Starting in 1988 through the last year of production of the 4L60E series transmission, GM installed load release springs in the input drum help counteract the accidental oil intrusion into the 3-4 clutch circuit. Without a sufficient air bleed, this trapped oil behind the 3-4 piston can allow the 3-4 clutch to partially apply in 1st and 2nd gear resulting in 3-4 clutch failure at high RPM’s. ![]() These transmissions often come in with complaints of erratic shifts, TCC slip as well as various solenoid performance and gear ratio codes. ![]() It is designed for the off-road driver only and for vehicles that do not have any TCM. This TransGo 6T70-A SHIFT KIT® Valve Body Repair Kit fits 2007 to 2013 General Motors vehicles equipped with GEN1 6T70 and 6T75 automatic transmissions. This kit delivers short firm shifts for performance as well as greater overall durability. Additionally, minor cross leaks can lead to fluid buildup behind the 3-4 apply piston and become trapped. This TransGo Reprogramming Kit provides full manual control for upshifting and downshifting 1st through 4th gear, there are no automatic shift functions retained. Will shift to any gear, at any speed, by moving lever. Trans will start off in whatever gear shifter is in.

This TransGo 4L6-CCV valve kit fits 1993 to 2015 General Motors vehicles equipped with the 4L60E. This 7-CS clutch spring kit fits 1982 to 2015 General Motors vehicles equipped with the 700R4/4L60, 4L60E, 4L65E and 4L70E automatic transmission. ![]()
