Toyota/Lexus vehicles equipped with U760E and U760F transmissions often exhibit several common concerns related to wear in the lockup control valve bore. Oscillation of the lockup control valve and stroking of the plunger valve in its sleeve results in wear that prevents full hydraulic control of the lockup circuit. TCC slip, RPM surge, harsh downshifts and/or slip codes can accompany the TCC apply/release concerns that develop in these cases. Sonnax oversized lockup control valve kit 47740-31K allows the bore to be refurbished, restoring normal TCC operation.
