Wear at the various OE end plugs in Toyota/Lexus U151E, U151F and U250E units allows critical circuit leakage of solenoid modulator, secondary regulator and line pressures. These pressure losses impair control of the clutches, resulting in various shift complaints and eventual failure. Sonnax O-ringed end plug kit 27741-20K contains all of the circuit sealing end plugs required to prevent this critical oil pressure loss.
