This U660E SHIFT KIT® Valve Body Repair Kit fits 2006 to 2018 Toyota and Lexus vehicles equipped with the U660E and U660F automatic transmissions. Common complaints with these transmissions are shuttle or flare on the 2-3 shift, slips with throttle in 3rd and/or 4th gear and TCC performance codes.
The first area of concern leading to the TCC complaints is a worn-out TCC boost valve and bushing. 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 other area of concern is a worn-out solenoid modulator valve bore. 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 modulating valve and spring are calibrated to prevent solenoid feed pressure from exceeding a predetermined PSI, no matter what main line pressure is. 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. If the pressure feeding the solenoids is too high or too low, output will also be too high or too low. As a result, shift quality complaints and codes can occur along with low or high main line pressure.
Features & Benefits:
The kit includes a drop-in USA-made hardened steel TCC boost valve and bushing to restores the hydraulic circuit integrity. Similarly, a new redesigned drop-in solenoid modulator valve system does not require any tooling. The furnished bushing and valve will restore the solenoid modulator valve function using the existing worn bore. Lastly, the drop-in USA-made hardened steel B2 Control vale utilizes an unworn area of the bore restoring the circuit integrity.

Shuttle or flare 2-3 shift
Slips with throttle in 3rd and/or 4th gear
TCC slip codes

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.
Was ist ein Schaltungssatz?
TransGo Shift Kit® Ventilkörper-Reparatursätze sind eine Kombination aus neuen und überarbeiteten Komponenten, die hauptsächlich im Ventilkörper, manchmal aber auch in der Pumpe oder sogar im Getriebe selbst eingebaut werden. Diese Kits beheben eine Vielzahl von typischen Problemen und Schwachstellen, die sich je nach Getriebemodell unterscheiden, wie z. B. die üblichen Verformungen und Abnutzungserscheinungen, und ermöglichen oft, dass ein Getriebe mit höherer Laufleistung besser funktioniert als ein neues. Typische Bestandteile eines Ventilkörper-Reparatursatzes sind Federn, Ventile, Rückschlagkugeln, Dichtungen, Trennplatten, etc..
