Sonnax Zip Kit U660E-ZIP targets the root cause of multiple complaints by sealing the critical circuit pressure losses in the Toyota/Lexus U660E valve body. The kit contains uniquely designed parts to prevent the loss of pressures within the main line, clutch apply control and lockup control circuits. The kit also seals multiple circuits known to suffer from end plug leakage or poor checkball sealing. No special tools are required for installing these parts. More Information
A340E AND A340F
Fits '00-Later V6 & V8, late models, Type 3 & 4 valve bodies.
The secondary pressure regulator valve in Toyota A340E/F late units receives regulated line fluid pressure from the main pressure regulator valve, and routes it to the converter and lubrication circuits. The continual oscillation of the steel valve within the aluminum casting creates wear, allowing this valuable fluid pressure to exhaust, resulting in converter complaints, burnt apply components and lube-related failures. The Sonnax oversized secondary pressure regulator valve kit 97741-18K restores proper hydraulic clearance in a refurbished bore and includes an O-ringed end plug to positively seal the balance pressure circuit.
Kit can be used to replace either OE ratio.
Toyota/Lexus vehicles equipped with U660E/F, U760E/F units commonly exhibit a number of symptoms related to line pressure instability. A few of these concerns are poor line rise and clutch/brake slippage, higher than normal pressures in reverse, erratic shifts and low converter feed pressure. These issues can frequently be traced to excess wear in the primary pressure regulator valve bore. To address these problems and restore full hydraulic control, Sonnax offers oversized primary pressure regulator and reverse boost valve kit 47740-02K.
In Toyota and Lexus U660E/F units, the steel OE solenoid modulator valve is prone to side-loading in the bore. This side-loading action, combined with repeated oscillation of the valve, prematurely wears the cast aluminum bore. The result is line pressure leakage and excessive SL, SLT, and SLU solenoid pressure, which floods the solenoids and creates shift quality concerns, solenoid codes, and deviation of proper control pressures available to various valves. Sonnax oversized solenoid modulator valve kit 47740-24K allows you to recondition the bore and install improved components to restore normal solenoid supply pressures.
Tool kit for 47740-24K and 47740-25K.
Sonnax F-Tool kits designed to service a specific bore require the VB-FIX, a self-aligning valve body reaming fixture.
