Disassembly Procedure

Caution
•  Disassemble the control valve body and replace the malfunctioning part only if there is a malfunction in the control valve body determined by the troubleshooting procedure and using the vehicle diagnostic tester (M-MDS).
However, if there is a malfunction in the parts other than the following, replace the control valve body with a new one because the parts other than the following are not shipped from the factory as a single component.
―  ON/OFF solenoid
―  Oil pressure switch A
―  Oil pressure switch B
―  Coupler component
•  Do not drop or apply a shock to the control valve body. Replace the control valve body with a new one if it was dropped or received an impact.
•  If the control valve body is placed with the shift solenoid side facing down on a workbench, the wiring harness or connector of the coupler component may be damaged. When placing the control valve body on a workbench, always place it with the control valve body connector side facing down. However, if the control valve body is directly placed on the workbench, the control valve body connector area or the sensor may be damaged. Always place the control valve body on an impact-absorbing material, which is free of foreign matter, so that the connector area and the sensor do not contact the workbench directly.

C  :Precision flathead screwdriver
Caution
•  Do not scratch the shift solenoid, shift solenoid connector, oil pressure switch and oil pressure switch connector with the precision flathead screwdriver.
•  When disconnecting the connectors, pulling the wiring harness may cause poor connection, do not pull the wiring harness.
(5)  Using pliers, detach the tie wrap clips secured to oil pressure switch A.

4.  Remove oil pressure switch A using the following procedure:

Caution
•  The pins for securing the solenoid valves are located in the areas circled with dotted lines, and they may drop down and be lost during oil pressure switch A removal.When removing oil pressure switch A, be careful not to drop the pins for securing the solenoid valves, and if they do drop, be careful that they do not get lost.
•  Never change the shift solenoid assembly position. If the assembly position is changed, it may cause a malfunction.
