DISASSEMBLY

NOTICE:
- Disassembling and reassembling should be conducted on a clean vinyl sheet or mat, or aluminum tray.
- Make the valve slide through the valve hole by its own weight. Do not forcibly pull out the valve using needle nose pliers. When having difficulty in removing it, slant and shake the valve body or use a magnet hand.
- Do not place the disassembled parts directly on metal work bench or waste cloth.
- Do not use dropped parts.
- Make sure that no burr is identified before assembling.





1. CHECK PRIMARY REGULATOR VALVE POSITION
Write down the relative position of the primary regulator valve sleeve, the plug and the pin.

NOTICE: Because the line pressure is changed by the position of the pin and the groove in the sleeve end, make sure to check the position.





2. REMOVE SHIFT SOLENOID VALVE
a. Remove the 5 bolts and 5 shift solenoid valves.
3. REMOVE LOWER VALVE BODY





a. Remove the 8 bolts.





b. Remove the 7 bolts, cover and gasket.





c. Remove the bolt, cover and 2 pressure relief balls.





d. Using snap ring pliers, remove the 2 snap rings.





e. Remove 4 springs from the valve body.
f. Remove 2 pistons from the valve body.





g. Remove the 7 bolts from lower value body.





h. Remove lower value body with plate from the upper value body.
