CONTROL VALVE BODY
Precaution
(1) Pay close attention when handling the control valve because it consists of the most precise and
delicate parts of the transaxle.
(2) Neatly arrange the removed parts in order to avoid mixing up similar parts.
(3) Disassemble the control valve assembly and thoroughly clean it when the clutch and/or brake
bands are burned, and/or when the automatic transaxle fluid is degenerated.
Disassembly
Disassemble in the sequence shown in the figure.
