c. Place mating surface of valve body face down, and remove
internal parts.
CAUTION:
 If a valve is hard to remove, place valve body face down
and lightly tap it with a soft hammer.
 Do not drop or damage valves and sleeves.
INSPECTION
Valve Springs
 Check each valve spring for damage or deformation. Also measure
free length and outer diameter. Refer to TM-321, "
Control Valves".
 Replace valve springs if deformed or fatigued.
Control Valves
Check sliding surfaces of valves, sleeves and plugs. Replace if necessary.
ASSEMBLY
CAUTION:
 Apply ATF to all components before installation.
 Lay control valve body down when installing valves. Do not
stand control valve body upright.
Lubricate control valve body and all valves with ATF. Install control
valves by sliding them carefully into their bores.
CAUTION:
 Install each control valve one by one.
 Install control valves after checking, because some of them
are similar.
 Do not scratch or damage valve body.
