Lastly, the EPC boost pressure relief valve system provided helps protect against accidental runaway boost pressure to stop the case and direct drum failure. In addition, the included highly improved wide land design boost valve and bushing resists wear so that pressure regulation functions consistently for the long haul.
Dual feeding the 3rd gear clutch triples the torque capacity of the 3rd gear clutch which is the Achilles heel of this transmission. Also, the laminated triple separator plate provides dual feed for the 3rd gear clutch without having to dismantle the transmission. Features and benefits: This TransGo Reprogramming Kit includes valve body, pump and internal components that are calibrated to work in concert with an elevated line pressure curve that will greatly improve the overall durability and shift feel of the transmission. On the other hand, the runaway boost pressure problem can result in a costly broken case, direct drum and piston failure. With the low boost pressure problem, the resulting complaints are a soft 2-3 shift, direct clutch failure as well as the gear ratio and solenoid performance codes. The boost valve assembly is notorious for wear causing both low pressure as well as runaway boost pressure. Common complaints on this transmission are, no upshifts, soft 2-3 shift, burnt direct frictions, broken hard parts as well as gear ratio and solenoid performance codes. Shift Kit Transgo Reprogramming HD2 1991/13 4L80E 4L85E This 4L80E-HD2 Reprogramming Kit fits 1991 to 2013 General Motors vehicles equipped with the 4L80E and 4L85E automatic transmission.
