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.

Be careful not to drop or damage valves and sleeves.
INSPECTION
Valve Springs

Check each valve spring for damage or deformation. Also mea-
sure free length and outer diameter. Refer to AT - 3 8 0 , "

Va l v e s" .

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.

Be careful not to scratch or damage valve body.
