DTC P0732 A/T 2ND GEAR FUNCTIONPFP:31940
DescriptionNCS001SG
This malfunction is detected when the A/T does not shift into 2nd 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 LogicNCS001SH

This is an OBD-II self-diagnostic item.

Diagnostic trouble code “P0732 A/T 2ND GR FNCTN” with CONSULT-III or 19th judgment flicker without
CONSULT-III is detected when TCM detects any inconsistency in the actual gear ratio.
Possible CauseNCS001SI

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 ProcedureNCS001SJ
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 “2ND GR FNCTN P0732” of “DTC WORK SUPPORT” mode for “TRANSMISSION” with CON-
SULT-III.

ACCELE POSI: 0.6/8 or more
ENGINE SPEED: TURBINE REV − 50 rpm or more
TURBINE REV: 300 rpm or more
GEAR: “2” 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 P0732 is shown, refer to “AT- 8 6 , "
Display Items List" ”.
If “COMPLETED RESULT NG” is detected, go to AT- 11 8 , "
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-

INSPECTION
Installation and Inspection of Torque Converter

After inserting a torque converter to a A/T, be sure to check dis-
tance “A” to ensure it is within the reference value limit.
INSTALLATION
Install the removed parts in the reverse order of the removal, while paying attention to the following work.

When installing A/T assembly to the engine assembly, attach the
fixing bolts in accordance with the following standard.
–: Engine to transmission
–: Transmission to engine

Align the positions of tightening bolts for drive plate with those of
the torque converter, and temporarily tighten the bolts. Then
tighten the bolts with the specified torque.
CAUTION:

When turning crankshaft, turn it clockwise as viewed from
the front of the engine.

When tightening the tightening bolts for torque converter
after fixing crankshaft pulley bolts, be sure to confirm the
tightening torque of crankshaft pulley mounting bolts.
Refer to EM-53, "
TIMING CHAIN" .

After converter is installed to drive plate, rotate crankshaft several turns and check to be sure that
transmission rotates freely without binding.
