1.
Move the shift lever to "N" range.
2.
Remove the valve body assembly.
(Refer to Hydraulic System - "Valve Body")
3.
Disconnect the input & output speed sensor connector (A).
4.
Loosen the solenoid valve harness bolts (B).

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

5.
Disconnect the solenoid valve connector (A).

6.
Remove the clip (A) and then remove the connector by pressing it downward.

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