| Shift Kit; For 4L80E, 4L85E Transmissions |
| 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 breakage
- Soft 2-3 shift
- Burnt direct clutch
- Slow 3-2 downshift
- No upshifts
- Harsh 1-2 shift
- Low pressure due to solenoid filter breakup
- Codes 39, 68, 85, 86, 87, P0731, P0732, P0733, P0734, P0751, P0756, P0894 and P1870
Includes:
- USA-made hardened boost valve and bushing
- Pressure regulator valve spacer, washer, springs and snap ring
- New stronger 4th feed bolt and washer
- (2) Direct and reverse feed hole cup seals
- Relief valve system plate, valve, spring, e-clip and drill bit
- (2) Accumulator valve springs, end plug and O-ring
- Actuator filter tapered plug, O-ring, spring and end plug
TransGo recommends using the 4L80E actuator feed limit valve boring kit (part # 48ACTTL) for all General Motors 4L80E rebuilds.
TransGo Shift Kit vs. Reprogramming Kit
Shift Kit® -- DESIGNED FOR DURABILITY
TransGo Shift Kit® valve body repair kits correct, prevent and reduce multiple transmission problems such as shift irregularities and durability issues. These kits are designed for normal everyday use and light duty towing.
Reprogramming Kit -- ENGINEERED FOR PERFORMANCE
TransGo Reprogramming Kit™ valve body performance kits are made for Heavy Duty and/or Performance applications, and include additional features such as:
- Gear Command™: Allows full control of downshifting and will hold any gear to any RPM. Retains automatic up shifts in the drive position. Certain units allow manual up shifts on driver command.
- Manual Shift Control: This feature fully converts the valve body to manual/stick shift operation – no automatic shifts. Most Manual Shift Control kits also allow you the ability to easily convert back to automatic.
- Tuneless: Patent-pending internal calibration technology “tuneless” allows install without the need for additional transmission tuning software or programmers.
What is a Shift Kit?
TransGo Shift Kit® valve body repair kits are a combination of new and re-engineered components that are primarily installed in the valve body, but sometimes the pump or even in the transmission itself. These kits solve a variety of inherent problems and weaknesses that differ by transmission model, including usual warp and wear, often allowing a higher mileage transmission to work better than a new one. Typical components of a valve body repair kit include springs, valves, check balls, gaskets, separator plates, etc.
