Automatic transmission-11 Diagnosis input solenoid valve 1and 2 S1 and S2 is the normal open solenoid valve, which is used to set the gear-position with other switch solenoid valve. It determines the static gear-position by operating the gear shift valve. Refer to Table 3.5, solenoid valve 3and 4 S3 and S4 are the normal-opened solenoid valve which is used to control the shifting quality and sequence in solenoid valve 5 S5 is the variable pressure solenoid valve which can release the pressure of gear-position shifting. It provides solenoid valve 6 S6 is the normal-opened solenoid valve, which is used to the set the H/L level of pipeline pressure. The solenoid valve 7 S7 is the normal-opened solenoid valve which is used to control the engagement status of torque converter Table 3.4 Status and function of solenoid valve Gear-position S1 S2 1 st -Gear On On 2 nd -Gear Off On 3 rd -Gear Off Off 4 th -Gear On Off R-Gear One of them is in On position at least.
