Use extreme care that the separator plate and oil

transfer plate do not separate.

A slight

separation could dislocate the check valve balls

and cause malfunction of the transmission.

Install the assembled modulator valve onto the

oil transfer plate as shown in figure 6-5.

Install three 1/4-

20 x 2 1/2-inch bolts to retain the modulator body, oil

transfer plate, separator plate and control valve

assembly as a unit.

Do not tighten the bolts at this time.

Aline the bolt holes in the control valve

assembly with those in the separator plate and oil

transfer plate.

When all bolt holes are alined, tighten the

bolts installed in (26), above, to 9 to 11 pound feet (12 to

15 Nm) torque.

(28)

Install manual selector valve 53 (fig. 6-7) into

bore O of the control valve body.

Valve 53 must be positioned so that its flat

side is upward (when assembly is positioned as in fig. 6-

8).

(30)

Install stop bolt 64 (B, foldout 16) into

control valve assembly.

The flat end of the bolt must

aline with the flat side of the selector valve (fig. 6-8).

Tighten the stop bolt to 36 to 43 pound feet (49 to 58

Nm) torque.
