ASSEMBLY
Upper Valve Body
1) Apply A/T fluid to each valve, plate washer, spring, plunger,
sleeve and key.
Insert primary regulator valve (2) about half way then place
plate washer and spring. Push in primary regulator valve
assembly all the way in. Insert plunger with sleeve and hold
them with the key.
2) Apply A/T fluid to each valve, sleeve, spring, plug and key
and insert them, then fix them with the key.
3) Install oil strainers (1) and put steel balls (2).NOTE:
 Note the location of the key shown in picture.
 Compression spring has a identification color paint of
yellow.
 Note the direction of the primary regulator valve.
NOTE:
Note the direction of the fail valve.
