The AF33-5 uses five electromagnetic shift solenoid valves to control upshifts and downshifts in all forward gear ranges. These shift solenoid valves are controlled by the TCM and work together in a combination of ON and OFF sequences to control the various shift valves. The TCM uses numerous inputs to determine which solenoid state combination the transmission should be in. The following table shows the solenoid state combination required for each gear range. refer to SHIFT SOLENOID VALVE STATE AND GEAR RATIO .
