Lastly, the TCC limit and lube regulator valve springs provided combats the excessive drain-back and loss of pump prime complaints on 2001-2003 models. Both increases in percentage values are when the lock-up clutch is off and line pressure is at maximum. Common complaints with this transmission are erratic shifts, broken parts, TCC slip as well as various solenoid performance and gear ratio codes. With this kit installed the friction torque capacity of the C2 is increased by approximately 111%, while the C3 and C4 brake is increased by approximately 100%. This TransGo 6T70-G2 SHIFT KIT® Valve Body Repair Kit fits 2013 and newer General Motors vehicles equipped with a GEN2 6T70, 6T75 and 6T80 automatic transmission. instructions SUCK THE BIG ONE, hope TransGo has.

The kit’s valve body components together with the internal modifications are designed to provide substantial gains in friction plate durability. Juice/Attitude, Transgo shift kit, Silencer ring removed, 3.73 gears, Off road tires. Complaints of no move after the vehicle has been parked with the engine off for an extended period of time are due to excessive torque converter drain-back and loss of pump prime. The C2 clutch is the weak link of this Allison transmission leading to 3-4 slip complaints as well as neutralizing under heavy load in 4 th and 5 th and burnt C2 clutch plates.

Note : The five-speeds have an external MLP switch, while the six-speeds have an internal MLP switch. Common complaints on this transmission are neutralizes under high load in 4 th or 5 th, burnt C2 clutch plates, no move forward or reverse, stuck in one gear as well as gear ratio and solenoid performance codes. Lastly, the drop-in USA-made hardened steel B2 Control vale utilizes an unworn area of the bore restoring the circuit integrity.This TransGo Allison SHIFT KIT® Valve Body Repair Kit fits 2001 to 2005 General Motors vehicles equipped with the Allison 1000, 20 five-speed automatic transmission. The furnished bushing and valve will restore the solenoid modulator valve function using the existing worn bore. Common complaints with these transmissions are shuttle or flare on the 2-3 shift, slips with throttle in 3rd and/or 4 th gear and TCC performance codes. Common complaints on this transmission are neutralizes under high load in 4 th or 5 th, burnt C2 clutch plates. Similarly, a new redesigned drop-in solenoid modulator valve system does not require any tooling. This U660E SHIFT KIT® Valve Body Repair Kit fits 2006 to 2018 Toyota and Lexus vehicles equipped with the U660E and U660F automatic transmissions. This TransGo Allison SHIFT KIT® Valve Body Repair Kit fits 2001 to 2005 General Motors vehicles equipped with the Allison 1000, 20 five-speed automatic transmission. TRANSGO 4L60E-PRO High Performance Valve Body Kit User Manual. For models with VLP solenoid and sensor, you need SK 42RLE-VLP. The kit includes a drop-in USA-made hardened steel TCC boost valve and bushing to restores the hydraulic circuit integrity. This TransGo 604 SHIFT KIT® Valve Body Repair Kit fits 1989 and newer Chrysler, Plymouth, Dodge, Eagle, Ram, Jeep and Mitsubishi vehicles equipped with the A604/41TE, A606/42LE and 42RLE automatic transmission without variable line pressure solenoid and sensor. As a result, shift quality complaints and codes can occur along with low or high main line pressure. If the pressure feeding the solenoids is too high or too low, output will also be too high or too low.

This is necessary to prevent more fluid from being fed to the solenoids than they can effectively regulate and to limit what max line pressure output is. The modulating valve and spring are calibrated to prevent solenoid feed pressure from exceeding a predetermined PSI, no matter what main line pressure is. The purpose of solenoid modulator valve is to limit the pressure going to solenoids, just like an AFL valve or solenoid pressure regulator valve does on other units. The other area of concern is a worn-out solenoid modulator valve bore. When the TCC boost valve and bushing wear out, the computer can no longer control the apply and release of the lock-up as it is supposed to. The first area of concern leading to the TCC complaints is a worn-out TCC boost valve and bushing. This U660E SHIFT KIT® Valve Body Repair Kit fits 2006 to 2018 Toyota and Lexus vehicles equipped with the U660E and U660F automatic transmissions.
