DTC Descriptor
DTC P0751
- Shift Solenoid (SS) 1 Valve Performance - Stuck OFF
DTC P0752
- Shift Solenoid (SS) 1 Valve Performance - Stuck ON
Circuit/System Description
The shift solenoid (SS) 1 is part of the control solenoid valve assembly which has no serviceable parts. The control solenoid valve assembly is
attached to the lower control valve body. The solenoid operates by the TCM opening or closing the ground circuit. With the solenoid circuit
grounded (solenoid on), the internal plunger and metering ball block the exhaust fluid creating signal fluid pressure. The signal fluid acts against
the clutch select valve 2 to overcome the valve spring force moving it to the apply position, allowing the shift. The TCM shifts the transmission by
operating the solenoids in on/off combinations.
