Pressure Switches
(PS-A, PS-B, PS-C, PS-D, PS-E)
Each of the five shift pressure control solenoids has a
corresponding pressure switch, which is normally
closed. The pressure switch is designed to open when
shift solenoid control pressure exceeds 40 psi. All five
of the pressure switches are identical and will
interchange in the solenoid body, as shown in Figure
7. Their particular functions are as follows:
PS-A = Coast Clutch
PS-B = Overdrive Clutch
PS-C = Intermediate Clutch
PS-D = Direct Clutch
PS-E = Low/Reverse Clutch
Refer to Figure 6 for their particular locations in the
solenoid body.
