4 ECT (ELECTRONIC CONTROLLED TRNSMISSION) SYSTEM OUTLINE REVIOUS UTOMTIC TRNSMISSIONS HVE SELECTED ECH GER SHIFT USING MECHNICLLY CONTROLLED THROTTLE HYDRULIC RESSURE, GOVERNOR HYDRULIC RESSURE ND LOCK U HYDRULIC RESSURE. THE ECT, HOWEVER, ELECTRICLLY CONTROLS THE LINE RESSURE ND LOCK U RESSURE ETC., THROUGH THE SOLENOID VLVE. ECT ECU CONTROL OF THE SOLENOID VLVE SED ON THE INUT SIGNLS FROM ECH SENSOR MKES SMOOTH DRIVING OSSILE Y SHIFT SELECTION FOR ECH GER WHICH IS MOST RORITE TO THE DRIVING CONDITIONS T THT TIME.. GER SHIFT OERTION DURING DRIVING, THE ECU SELECTS THE SHIFT FOR ECH GER WHICH IS MOST RORITE TO THE DRIVING CONDITIONS, SED ON INUT SIGNLS FROM THE EFI WTER TEM. SENSOR TO TERMINL THW OF THE ECU, ND LSO THE INUT SIGNLS TO TERMINL S OF THE ECU FROM THE SEED SENSOR DEVOTED TO THE ECT. CURRENT IS THEN OUTUT TO THE ECT SOLENOIDS. WHEN SHIFTING TO ST SEED, CURRENT FLOWS FROM TERMINL S OF THE ECU TERMINL OF THE ECT SOLENOIDS GROUND, ND CONTINUITY TO THE NO. SOLENOID CUSES THE SHIFT. FOR ND SEED, CURRENT FLOWS FROM TERMINL S OF THE ECU TERMINL OF THE ECT SOLENOIDS GROUND, ND FROM TERMINL S OF THE ECU TERMINL OF THE ECT SOLENOIDS GROUND, ND CONTINUITY TO SOLENOIDS NO. ND NO. CUSES THE SHIFT. FOR RD SEED, THERE IS NO CONTINUITY TO NO. SOLENOID, ONLY TO NO., CUSING THE SHIFT. SHIFTING INTO TH SEED (OVER DRIVE) TKES LCE WHEN THERE IS NO CONTINUITY TO EITHER NO. OR NO. SOLENOID.. LOCK U OERTION WHEN THE ECT ECU JUDGES FROM ECH SIGNL THT LOCK U OERTION CONDITIONS HVE EEN MET, CURRENT FLOWS FROM TERMINL SL OF THE ECT ECU TERMINL OF THE ECT SOLENOID GROUND, CUSING CONTINUITY TO THE LOCK U SOLENOID ND CUSING LOCK U OERTION.. STO LIGHT CIRCUIT IF THE KE EDL IS DERESSED (STO LIGHT ON) WHEN DRIVING IN LOCK U CONDITION, SIGNL IS INUT TO TERMINL /K OF THE ECU, THE ECU OERTES ND CONTINUITY TO THE LOCK U SOLENOID IS CUT.. OVERDRIVE CIRCUIT * O/D MIN ON WHEN THE O/D MIN IS TURNED ON (O/D OFF INDICTOR LIGHT TURNS OFF), SIGNL IS INUT TO TERMINL OD OF THE ECU ND ECU OERTION CUSES GER SHIFT WHEN THE CONDITIONS FOR OVERDRIVE RE MET. * O/D MIN OFF WHEN THE OVERDRIVE IS TURNED TO OFF, THE CURRENT FLOWING THROUGH THE O/D OFF INDICTOR LIGHT FLOWS THROUGH THE O/D MIN TO GROUND. CUSING THE INDICTOR LIGHT TO LIGHT U. T THE SME TIME, SIGNL IS INUT TO TERMINL OD OF THE ECU ND ECU OERTION REVENTS SHIFT INTO OVERDRIVE. 5. ECT TTERN SELECT CIRCUIT IF THE ECT TTERN SELECT IS CHNGED FROM NORML TO OWER, THE CURRENT FLOWING THROUGH THE OWER INDICTOR FLOWS TO GROUND, CURRENT FLOWS TO TERMINL OF THE ECT ECU, THE ECU OERTES, ND SHIFT U ND SHIFT DOWN OCCUR T HIGHER VEHICLE SEEDS THN WHEN THE IS IN NORML OSITION.
