6 SPD A/T SOLENOID REPLACEMENT – MULTIPLE DTCS

This bulletin provides information relating to the replacement of various shift solenoids on 6-speed
automatic transaxles with DTCs P0741, P0743, P0748, P0753, P0758, P0763, P0768, P0773,
P1778 and P2709. Replace the solenoids if current or history codes are present; Do not replace the
transaxle. To reduce vehicle repair time, this procedure can be performed with the transaxle
installed in the vehicle. Refer to KGIS for solenoid pack removal and reinstallation procedures for
the specific year and model of the vehicle.

6 SPD A/T SOLENOID REPLACEMENT – MULTIPLE DTCS

Service Procedure:
1. Using GDS, check for DTC in the “Automatic Transaxle” menu. Record the DTC and
description. Delete the DTC.
2.

From GDS, select the following parameters: Vehicle and A/T menu > “Actuation Test”

Press the “Start” button and check the “Result” box for a message indicating “Success”.

3.

If the test results show:
 “Success” – GDS requested the TCM to activate the solenoids. Use chassis ears or
stethoscope to listen for solenoid operation. If the solenoids are audible, the harness
currently has no open/short circuit. Proceed to Step 5.
 “Failure” - The GDS did not request the TCM to activate the solenoids. Proceed to Step 4.

4.

Visually check the wiring harness between the PCM and transmission for a damaged wire or
short circuit to ground. Check for a damaged pin or pin not fully inserted into the connector.
 If damage exists, repair or replace the ECM control harness and drive the vehicle to
confirm the repair.
 If not, proceed to Step 5.



STEEL OIL PAN:
Apply Kia RTV Silicone Gasket Maker
(P/N UM010 CH046) to the oil pan and
reinstall it.



PLASTIC OIL PAN:
Install a new gasket to the oil pan and
reinstall it.

For Idle Stop and Go (ISG) equipped
vehicles, allow the vehicle to remain
undisturbed for 4 hours after all repairs
are complete. This will allow for the
required self-recalibration of the system
to take place. Otherwise, the ISG
system will not operate correctly.

 NOTICE
Refer to KGIS or TSB TRA 046 for information on ATF requirements by model. Refill
the transmission with the same amount of fluid as was drained during removal
process.

9.



Attach the GDS to the DLC and select
vehicle > A/T menu > Current Data >
Oil Temperature Sensor.



Start the engine and remove the level
checking plug when the ATF is within
122°F~140°F (50~60°C). The level is
correct when oil flows out of the level
checking plug in a thin steady stream.

 NOTICE
Refer to PS171 for information on fluid
level checking on vehicles equipped
with plastic oil pans.


Filling and checking of fluid level is
done through valve body side cover

Clear the codes and test drive the vehicle for two driving cycles (two key-on to key-off driving
cycles, including 1-2-3-4-5-6 upshifts and 6-5-4-3-2-1 downshifts). If the DTC returns, perform
the following repairs:

P0758



Replace the control wiring harness between the PCM and transmi
ssion. If the solenoid DTCs do not return, release the vehicle to th
e customer.



If any of the solenoid DTCs return again, replace the PCM.

11.

After all repairs are complete, test drive the vehicle for two driving cycles (two key-ON to keyOFF driving cycles, including 1-2-3-4-5-6 upshifts and 6-5-4-3-2-1 downshifts) to confirm the
DTC no longer returns, and for proper transmission operation

12.

Test drive the vehicle to confirm proper transmission operation.
