DTC P0735 A/T 5TH GEAR FUNCTIONPFP:31940
DescriptionNCS001SV
This malfunction is detected when the A/T does not shift into 5th gear position as instructed by TCM. This is
not only caused by electrical malfunction (circuits open or shorted) but also by mechanical malfunction such
as control valve sticking, improper solenoid valve operation.
On Board Diagnosis LogicNCS001SW

This is an OBD-II self-diagnostic item.

Diagnostic trouble code “P0735 A/T 5TH GR FNCTN” with CONSULT-III or 22th judgment flicker without
CONSULT-III is detected when TCM detects any inconsistency in the actual gear ratio.
Possible CauseNCS001SX

Harness or connectors
(Solenoid circuits are open or shorted.)

Input clutch solenoid valve

Front brake solenoid valve

Direct clutch solenoid valve

High and low reverse clutch solenoid valve

Each clutch

Hydraulic control circuit
DTC Confirmation ProcedureNCS001SY
CAUTION:
Always drive vehicle at a safe speed.
NOTE:
If “DTC Confirmation Procedure” has been previously performed, always turn ignition switch OFF and
wait at least 10 seconds before performing the next test.
After the repair, perform the following procedure to confirm the malfunction is eliminated.
WITH CONSULT-III
1. Start the engine and select “DATA MONITOR” mode for “TRANSMISSION” with CONSULT-III.
2. Make sure that “ATF TEMP 1” is within the following range.
ATF TEMP 1: 20°C – 140°C
If out of range, drive vehicle to warm ATF or stop engine to cool ATF.
3. Select “5TH GR FNCTN P0735” of “DTC WORK SUPPORT” mode for “TRANSMISSION” with CON-
SULT-III.
4. Drive vehicle and maintain the following conditions.
VEHICLE SPEED: 10 km/h (6 MPH) or more
ACCELE POSI: 0.6/8 or more
ENGINE SPEED: TURBINE REV − 50 rpm or more
TURBINE REV: 300 rpm or more
GEAR: “5” position
MANU MODE SW: ON
5. Keep the current driving status for at least 5 consecutive seconds if CONSULT-III screen changes from
“OUT OF CONDITION” to “TESTING”.
CAUTION:
If “TESTING” does not appear on CONSULT-III for a long time, select “SELF-DIAG RESULTS”. In
case a 1st trip DTC other than P0735 is shown, refer to “AT- 8 6 , "
Display Items List" ”.
If “COMPLETED RESULT NG” is detected, go to AT- 1 2 4 , "
Diagnostic Procedure" .
If “STOP VEHICLE” is detected, go to the following step.
6. Stop vehicle.
7. Drive vehicle in “D” position allowing it to shift from 1st to 5th gear and check shift timing and shift shock.
–Touch “OK” to complete the inspection when normally shifted from the 1st to 5th gear.
–Touch “NG” when an unusual shift shock, etc. occurs in spite of shifting from the 1st to 5th gear. Go to AT-
52, "ROAD TEST" .

DTC P0740 TORQUE CONVERTER CLUTCH SOLENOID VALVEPFP:31940
DescriptionNCS0003I

Torque converter clutch solenoid valve is activated, with the gear in D4 , D5 , M2 , M3 , M4 and M5 by the
TCM in response to signals sent from the vehicle speed sensor and accelerator pedal position sensor
(throttle position sensor). Torque converter clutch piston operation will then be controlled.

Lock-up operation, however, is prohibited when A/T fluid temperature is too low.

When the accelerator pedal is depressed (less than 1.0/8) in lock-up condition, the engine speed should
not change abruptly. If there is a big jump in engine speed, there is no lock-up.
CONSULT-III Reference ValueNCS0003J
