Pinpoint Test K: Odd Clutch Pressure Control Solenoids

WARNING: This page is about a different variant/trim than selected.
  1. Refer to TRANSMISSION CONTROLS - TR9070 for schematic and connector information.

    Normal Operation and Fault Conditions 

    The TR9070 uses 2 clutches, the even clutch and the odd clutch, to transmit engine power to the gearbox. Each clutch directs power to 4 gears in the transmission. The clutches are controlled by hydraulic pressure from the clutch control valve body. Pressure control solenoid "A", also called the odd clutch pressure control valve (OCPV), and pressure control solenoid "C", also called the odd redundant shut-off valve (ORSV), are used to engage and disengage the odd gear clutch. Pressure control solenoid "F", also called the odd clutch cooling flow control valve (OCFV), controls fluid flow to the transmission fluid cooler. All 3 odd clutch control valves receive power from the TCM through the transmission solenoid power control 1 (TSPC1) circuit. The TCM controls each solenoid through dedicated low side drivers.
