DTC Description Component Action
P073DUnable to Engage NeutralDirect or forward clutch
pack
This DTC may set when there is a mechanical/hydraulic concern with the
direct or forward clutch pack, possibly deformed clutch plates or a rolled
clutch seal allowing the direct clutch or the forward clutch to mechanically or
hydraulically apply in neutral. PLACE the transmission in neutral with the
engine running to see if there is any creep torque, this fault causes the
transmission to partially engage forward gear in neutral. This DTC may set
with P0752, P0757, P0762, and/or P0767. CLEAR the DTC . If the DTC
returns, check the transmission for internal failure.

Pinpoint Tests
Power is routed through the transmission solenoid power control relay (inside the PCM ) to all transmission solenoids. If the power
circuit to the transmission solenoids or the transmission solenoid power control relay fails open, all solenoids are failed electrically off.
Check for open, short to ground or the transmission connector disconnected. The transmission solenoid power control relay disables
power to the transmission solenoids when certain transmission DTC s are set.
• Carry out KOEO and KOER procedures.
• Retrieve and record all DTC s.
• Repair all non-transmission DTC s first.
• Repair all transmission DTC s second.
• Clear all 2WD CMDTC s and attempt to repeat them.
• Repair all CMDTC s.
• If only pass codes are obtained, REFER to: Diagnosis By Symptom(307-01 Automatic Transmission - 6-Speed Automatic
Transmission - 6F35, Diagnosis and Testing). for further information and diagnosis.

Normal Operation and Fault Conditions
The PCM applies and releases the various clutches in the transmission by actuating the shift solenoids in the solenoid body. Shift
Solenoid A (SSA) is a Variable Force Solenoid (VFS).
NOTE:Without a voltage signal return to the PCM , the transmission solenoid power control relay is commanded off. Using a fused
jumper wire between a transmission solenoid control circuit and the signal return circuit, the transmission solenoid power control relay
circuit supplies power to the transmission solenoids when the ignition is cycled from off to on. Do not use a solenoid control circuit that
may be at fault, refer to DTC Charts for a fault listing.

Normal Operation and Fault Conditions
Shift Solenoid E (SSE) controls the multiplexing of the Shift Solenoid D (SSD) low/reverse and overdrive clutch. If Shift Solenoid E
(SSE) fails off (no pressure) then 1st gear is failed to 4th gear. If clutch select valve 2 sticks in the default position then 1st gear with
engine braking is failed to 4th gear and reverse is failed to neutral. Shift Solenoid E (SSE) is an On/Off solenoid.
NOTE:Without a voltage signal return to the PCM , the transmission solenoid power control relay is commanded off. Using a fused
jumper wire between a transmission solenoid control circuit and the signal return circuit, the transmission solenoid power control relay
circuit supplies power to the transmission solenoids when the ignition is cycled from off to on. Do not use a solenoid control circuit that
may be at fault, refer to DTC Charts for a fault listing.

Normal Operation and Fault Conditions
The transmission solenoid power control relay controls vehicle power to all solenoids. Power is routed through the transmission
solenoid power control relay (inside the PCM ) to all transmission solenoids. If the power circuit to the transmission solenoids or the
transmission solenoid power control relay fails open, all solenoids are failed electrically off. Check for open, short to ground or the
transmission connector disconnected. The transmission solenoid power control relay disables power to the transmission solenoids
when certain transmission DTC s are set.
NOTE:Without a voltage signal return to the PCM , the transmission solenoid power control relay is commanded off. Using a fused
jumper wire between a transmission solenoid control circuit and the signal return circuit, the transmission solenoid power control relay
circuit supplies power to the transmission solenoids when the ignition is cycled from off to on. Do not use a solenoid control circuit that

Refer to Wiring Diagrams Cell 29 for schematic and connector information.
Normal Operation and Fault Conditions
The TFT sensor is located in the solenoid body leadframe. The resistance value of the TFT sensor varies with temperature change.
The PCM monitors the voltage drop across the TFT sensor to determine the temperature of the transmission fluid. When the ignition is
turned to the run position, the PCM uses this initial input signal to determine whether a cold start shift schedule is necessary. The cold
start shift schedule allows delayed shifts when the transmission fluid is cold. The PCM inhibits TCC operation at low transmission fluid
temperatures and adjusts line pressure to temperature.

The PCM controls torque converter lock-up by varying the amount of current applied to the TCC solenoid. When no current is applied
to the TCC solenoid, the TCC is fully released. When maximum current is applied, the TCC is fully applied.
