Fig. 158: Shift Solenoid Valve Driving Signal Combination Table 

General Description 

Shift solenoid valve D is installed in the transmission housing. It is controlled by the ON/OFF signal from 
the powertrain control module (PCM) to apply line pressure to lock-up shift valve. The signal from the PCM 
is output to apply clutch pressure control pressure to the proper gear change clutch according to the gear 
change schedule. When the signal to shift solenoid valve D from the PCM is ON, and line pressure is 
applied to the lock-up shift valve, it operates against the lock-up shift valve spring. When the signal to shift 
solenoid valve D from the PCM is OFF, and line pressure is discharged, the lock-up shift valve is inactive. 
The PCM monitors the input shaft (mainshaft) speed and the output shaft (countershaft) speed at the gear 
change determined by the shift schedule. When an improper gear ratio is output compared to the 
predetermined gear change mode, a shift solenoid valve D OFF failure is detected and a DTC is stored.

Malfunction Threshold 

One of these symptoms occurs. 

MALFUNCTION THRESHOLD SYMPTOM 1 

MALFUNCTION THRESHOLD SYMPTOM 2 

Driving Pattern 

Start the engine, and accelerate the vehicle until the transmission shifts into 5th gear in the D position. 

Drive the vehicle in this manner only if the traffic regulations and ambient conditions allow.  

Diagnosis Details 

Conditions for illuminating the MIL 

When a malfunction is detected during the first drive cycle, a Temporary DTC is stored in the PCM 
memory. If the malfunction recurs during the next (second) drive cycle, the MIL comes on and the DTC and 
the freeze frame data are stored. 

Conditions for clearing the MIL 

The MIL will be cleared if the malfunction does not recur during three consecutive trips in which the 
diagnostic runs. 

The MIL, the DTC, the Temporary DTC, and the freeze frame data can be cleared by using the scan tool 
Clear command or by disconnecting the battery.

ENABLE CONDITIONS 

Malfunction Threshold 

One of these conditions occurs. 

The actual gear position is neutral for at least 3 seconds when 1st gear in-gear is commanded, though 
there is no record of being in neutral when reverse gear in-gear is commanded.  

The actual gear position is neutral for at least 3 seconds though 1st gear in-gear is commanded and 
reverse drive occurred during this driving cycle.  

Driving Pattern 

Start the engine, and accelerate the vehicle until the transmission shifts into 5th gear in the D position. 

Drive the vehicle in this manner only if the traffic regulations and ambient conditions allow.
