TROUBLESHOOTING HINTS (THE MOST 
LIKELY CAUSES FOR THIS CODE TO BE 
SET ARE:)

• Transaxle assembly powertrain parts failure

• Malfunction of the P0715: input shaft speed sen-

sor system

• Malfunction of the P0720: output shaft speed 

sensor system

• Malfunction of the P0748: line pressure linear 

solenoid valve system circuit

• Malfunction of the P0753: low clutch linear sole-

noid valve system circuit

• Malfunction of the P0758: 2-6 brake linear sole-

noid valve system circuit

• Malfunction of the P0763: 3-5 reverse clutch lin-

ear solenoid valve system circuit

• Malfunction of the P0768: high clutch linear sole-

noid valve system circuit

• Malfunction of the P1753: low clutch shift sole-

noid valve system circuit

• Malfunction of the low clutch, 2-6 brake, 3-5 

reverse clutch, high clutch

• Malfunction of the valve body assembly

DIAGNOSIS

STEP 1. Check the DTC.
Check that P0715 (input shaft speed sensor) and P0720 (out-
put shaft speed sensor) are set.
Q: Is the DTC set?

YES : Check and repair the relevant DTC system.
NO :  Go to Step 2.
