Circuit / System Description
The TFP switch?5 is part of the control solenoid (w/body and TCM) valve assembly and is not serviced separately. The TCM supplies 12?volts to the TFP switch?5 on the TFP switch?5 signal circuit; the TFP switch?5 has an internal case ground. TFP switch?5 is normally closed, Low. When oil pressure is present at the TFP switch?5, the switch is open, high. The normally low clutch PC solenoid?3 controls the transmission fluid to the R1/4-5-6 clutch. The TCM monitors the normally closed TFP switch?5 signal circuit to determine the R1/4-5-6 clutch status.
