9.8 ~ 11.8 N.m (1.0 ~ 1.2 kgf.m, 7.2 ~ 8.7 lb-ft)

5.
Lift the vehicle after loosening valve body cover upper bolts.
6.
Remove the valve body cover (A) by loosening bolts.
Tightening torque:
11.8 ~ 13.7 N.m (1.2 ~ 1.4 kgf.m, 8.7 ~ 10.1 lb-ft)

7.
Remove the solenoid valve harness (A) and oil temperature sensor (B) after removing the bolts.
Tightening torque:
9.8 ~ 11.8 N.m (1.0 ~ 1.2 kgf.m, 7.2 ~ 8.7 lb-ft)

8.
Remove solenoid valve support bracket (A).
Tightening torque:
9.8 ~ 11.8 N.m (1.0 ~ 1.2 kgf.m, 7.2 ~ 8.7 lb-ft)

9.8 ~ 11.8 N.m (1.0 ~ 1.2 kgf.m, 7.2 ~ 8.7 lb-ft)

Installation
1.
Install in the reverse order of removal.
  
The existing valve body cover gasket (A) must be replaced with a new one. (Do not reuse it.)

2.
Perform the procedures below after installing.
(1)
Refill the automatic transaxle with fluid.
(Refer to Hydraulic System - "Fluid")
(2)
Clear the diagnostic trouble codes (DTC) using the KDS/GDS. Disconnecting the battery negative terminal will not clear the DTCs. Clear DTCs using the KDS/GDS at all times.
(3)
Reset the automatic transaxle adaptive values using the KDS/GDS.

(4)
Perform the TCM adaptive values learning procedure.
(Refer to Automatic Transaxle Control System - "Adjustment")
(5)
After installing, check for leakage of coolant or fluid from hose connection during engine start.
