Install upper, inter and lower body. Place oil circuit of upper body face up. Install steel balls in their proper positions. Install upper separating gasket, upper inter separating gasket and upper separating plate in order shown in illustration. Install reamer bolts f from bottom of upper body. Using reamer bolts as guides, install separating plate and gaskets as a set. Install pilot filter. Place lower body as shown in illustration (side of inter body face up). Install steel balls in their proper positions. Install inter body on upper body using reamer bolts f as guides. Be careful not to dislocate or drop steel balls. Install check balls and oil cooler relief valve springs in their proper positions in lower body. Install lower separating gasket, lower inter separating gasket and lower separating plate in order shown in illustration. Install bolts e from bottom of lower body. Using bolts e as guides, install separating plate and gaskets as a set. Temporarily install support plates on lower body. Install lower body on inter body using reamer bolts f as guides and tighten reamer bolts f slightly.
Install O-rings to solenoid valves and terminal body. Apply ATF to O-rings.
