N: DTC P0736 REVERSE INCORRECT RATIO
DTC DETECTING CONDITION:
Target gear ratio and actual gear ratio do not match.
TROUBLE SYMPTOM:
•Shift point is too high or too low.
•Excessive shift shock.
•Gear is not changed.
•The vehicle does not move in D or R range with the engine running at high speed.
Step Check Yes No
1CHECK DTC OF TCM.Is any DTC of the followings
detected? P0715, P0720,
P0753, P0758, P0763, P0768,
P0773, P0751, P0756, P0761,

Pe r for m t h e d ia g -
nosis according to
DTC.
Go to step 2.
2CHECK TURBINE SPEED SENSOR USING
SUBARU SELECT MONITOR.
1) Lift-up the vehicle and support with rigid
racks.
NOTE:Raise all wheels off floor.
2) Start the engine, and drive it.
3) Read the current data of torque converter
turbine speed using Subaru Select Monitor.
DATA, OPERATION, Subar u Select Monitor.>
NOTE:The speed difference between front and rear
wheels may light the ABS warning light, but this
indicates no malfunction. When AT control di-
agnosis is finished, perform the VDC memory
clearance procedure of on-board diagnostics
system. ORY MODE, OPERATION, Subaru Select
Monitor.>
Does the displayed value of the
Subaru Select Monitor change
according to engine speed and
shifting?
Go to step 3.Perform the diag-
nosis according to
DTC P0715,
P1710.
3CHECK FRONT AND REAR VEHICLE
SPEED SENSORS.
Do the values displayed for
each of the Subaru Select
Monitor and the speedometer
substantially match?
Go to step 4.Perform the diag-
nosis according to
DTC P0720,
P1706.
4CHECK INHIBITOR SWITCH.Do the values displayed for the
Subaru Select Monitor and the
meter indicator match?
Go to step 5.Perform the diag-
nosis according to
DTC P0705.
5DRIVING CHECK.
1) Turn the ignition switch to OFF.
2) After restarting the engine, check that the
SPORT indicator light is not blinking, and per-
form a drive check based on the inspection
mode. Inspection Mode.>
Is DTC displayed again? Check the DTC.
Then, when pro-
ceeded again to
step 5, go to step
6.
Go to step 6.
6CHECK AFTER REPAIR.Is the trouble symptom inre-
pairable (malfunction in shifting
such as excessive shift shock,
engine speed increases exces-
sively when shifting)?
Replace the trans-
mission assembly.
Te m p o r a r y p o o r
contact occurs.
Check that the
harness connec-
tor is not faulty.

DTC DETECTING CONDITION:
•Defective lock-up clutch or torque converter assembly
•Defective control valve
•Defective turbine speed sensor 1 or 2
TROUBLE SYMPTOM:
No lock-up occurs. (After engine is warmed-up)
Step Check Yes No
1CHECK DTC OF TCM.Is any DTC of the followings
detected? P0715, P0725,

Pe r for m t h e d ia g -
nosis according to
each DTC.
Go to step 2.
2DRIVING CHECK FOR LOCK-UP CONDI-
TION
1) Perform a drive check based on the inspec-
tion mode with the following conditions. to 5AT(diag)-19, PROCEDURE, Inspection
Mode.>
(1) Read the current data of throttle open-
ing angle using Subaru Select Monitor.
DATA, O PER ATION, Subar u Select Moni-
tor.>
(2) Keep the same vehicle speed at 60 km/
h with 10% or less throttle opening angle
which is read currently on Subaru Select
Monitor. CURRENT DATA, OPERATION, Subaru
Select Monitor.>
(3) Read the current data of L/U solenoid
target pressure using Subaru Select Moni-
tor. RENT DATA, OPERATION, Subaru Select
Monitor.>
(4) Check the engine speed and turbine
speed when the L/U solenoid target value
displayed on Subaru Select Monitor is 500
kPa or more.
Are the engine speed and tur-
bine speed almost the same?
Te m p o r a r y p o o r
contact or open
circuit occurs.
Recheck that the
harness connec-
tor has no faulty.
Go to step 3.
