1-2 Shift Solenoid Valve Replacement
Removal Procedure
Important: Retainer clips hold in each of the valve line-ups. Use a small screwdriver in order to remove the retainer clips. Be careful not to
score the valve body when removing the retainer clips and valves. Before removing the valve line-ups, inspect each valve line-up for freedom of
movement.
1. Remove the transmission side cover. Refer to Control Valve Body Cover Replacement (See: Automatic Transmission/Transaxle/Valve
Body/Service and Repair/Control Valve Body Cover Replacement) .
2. Remove the 1-2 shift solenoid retainer clip (304), the 1-2 shift solenoid (305) with O-ring (303), the 1-2 shift valve (302), and the 1-2 shift valve
spring (301).
Installation Procedure
1. Install the 1-2 shift valve spring (301), the 1-2 shift valve (302), the 1-2 shift solenoid (305) with O-ring (303) and the 1-2 shift solenoid retainer
clip (304).
2. Install the transmission side cover. Refer to Control Valve Body Cover Replacement (See: Automatic Transmission/Transaxle/Valve
Body/Service and Repair/Control Valve Body Cover Replacement) .
Important: It is recommended that transmission adaptive pressure (TAP) information be reset.
Resetting the TAP values using a scan tool will erase all learned values in all cells. As a result, The ECM, PCM or TCM will need to
relearn TAP values. Transmission performance may be affected as new TAP values are learned.
3. Reset the TAP values. Refer to Transmission Adaptive Functions (See: Automatic Transmission/Transaxle/Description and
Operation/Transmission Adaptive Functions) .
