and front suspension member (2).
CAUTION:
• Always insert a wooden block between oil pan (upper) of
engine and front suspension member when removing A/T
assembly from the engine. (Because VVEL control shaft
position sensor may be damaged by the interference
between VVEL control shaft position sensor and dash
panel if the operation is performed without the wooden
block inserted.)
