3. Test-drive the vehicle in 5th gear, with the shift lever in D, at speeds over 7 mph (12 km/h), and  
with the engine speed above 1, 000 rpm for at least 12 seconds.  
4. Monitor the OBD STATUS for P0735 in the DTCs MENU with the HDS.  
DTC Description  
OBD Status  
P0735 5th Gear Incorrect Ratio  
Does the HDS indicate FAILED?  
YES : The failure is duplicated. Replace the 4th/5th clutch or the transmission See AUTOMATIC  
TRANSMISSION DISASSEMBLY AND REASSEMBLY or AUTOMATIC TRANSMISSION  
REMOVAL AND INSTALLATION , then do the repair verification .  
NO : If the HDS indicates PASSED, intermittent failure, the system is OK at this time. If the HDS  
indicates NOT COMPLETED, test-drive again.

1. ATF check:  
ο‚‘
ο‚‘
ο‚‘
1. Warm up the engine to normal operating temperature (the radiator fan comes on).  
2. Make sure that the transmission is filled to the proper level, and check for fluid leaks.  
3. DRAIN THE ATF through a strainer. Inspect the strainer for metal debris or excessive clutch  
material.  
Does the strainer have metal debris or excessive clutch material?  
YES : Replace the transmission See AUTOMATIC TRANSMISSION DISASSEMBLY AND  
REASSEMBLY or AUTOMATIC TRANSMISSION REMOVAL AND INSTALLATION , then do  
the repair verification .  
NO : REPLACE THE ATF , then go to step 2.  
2. Shift solenoid valve E operation check:  
ο‚‘
ο‚‘
ο‚‘
1. Turn the ignition switch to ON (II).  
2. Clear the DTC with the HDS.  
3. Select Shift Solenoid Valve E in the Miscellaneous Test Menu, and check that shift solenoid  
valve E operates with the HDS.  
Is a clicking sound heard?  
YES : Shift solenoid valve E is OK. Go to step 3.  
NO : REPLACE SHIFT SOLENOID VALVE E , then do the repair verification .  
3. A/T clutch pressure control solenoid valve A operation check:  
ο‚‘
1. Run the engine until the Engine Coolant Temperature reaches 176 Β°F (80 Β°C) with the HDS in  
the A/T Data List.

2. Select Clutch Pressure Control (Linear) Solenoid Valve A in the Miscellaneous Test Menu, and  
test A/T clutch pressure control solenoid valve A with the HDS.  
Does the HDS indicate NORMAL?  
NORMAL A/T clutch pressure control solenoid valve A is OK. Go to step 4.  
FAILURE Follow the instructions indicated on the HDS according to the test result. If a part is replaced,  
do the repair verification .  
4. Problem verification (OBD STATUS check):

ο‚‘
1. Turn the ignition switch to ON (II).  
2. Clear the DTC with the HDS.  
3. Test-drive the vehicle on a level road with a steady speed at 60 mph (96 km/h) for at least 20  
seconds.  
ο‚‘
4. Monitor the OBD STATUS for P0741 in the DTCs MENU with the HDS.  
DTC Description  
OBD Status  
P0741 Torque Converter Clutch Circuit Performance or Stuck OFF  
Does the HDS indicate FAILED?  
YES : The failure is duplicated. Faulty torque converter clutch mechanism, lock-up control valve, or  
lock-up shift valve. Repair the hydraulic system related with these parts, or replace the torque converter,  
the main valve body (lock-up control valve), the regulator valve body (lock-up shift valve), or the  
transmission See AUTOMATIC TRANSMISSION DISASSEMBLY AND REASSEMBLY or  
AUTOMATIC TRANSMISSION REMOVAL AND INSTALLATION , then do the repair  
verification .  
NO : If the HDS indicates PASSED, intermittent failure, the system is OK at this time. If the HDS
