4. Remove the stator shaft (E) and stator shaft stop (F), then remove the regulator separator plate (G) and two dowel pins (H).

5. Remove the servo body (I) (12 bolts), then remove the separator plate (J) and two dowel pins (K).

6. Remove the cooler check valve spring (L) and valve (M), then remove the main valve body (N) (three bolts). Do not let the check balls (O) fall out.

7. Remove the ATF pump driven gear shaft (P), then remove the ATF pump gears (Q).

8. Remove the main separator plate (R) and two dowel pins (S).

9. Remove the ATF magnet (T), clean and reinstall it in the torque converter housing (U).

10. Clean the inlet opening (A) of the ATF strainer (B) thoroughly with compressed air, then check that it is in good condition and that the inlet opening is not clogged.

11. Test the ATF strainer by pouring clean ATF through the inlet opening, and replace it if it is clogged or damaged.

12. Remove the O-rings (V) (W) from the stator shaft and ATF strainer. Install the new ones when installing the valve bodies.

Valve Body Repair

NOTE: This repair is only necessary if one or more of the valves in a valve body do not slide smoothly in their bores. Use this procedure to free the valves.

1. Soak a sheet of # 600 abrasive paper in ATF for about 30 minutes.

2. Carefully tap the valve body so the sticking valve drops out of its bore. It may be necessary to use a small screwdriver to pry the valve free. Be careful not to scratch the bore with the screwdriver.

3. Inspect the valve for any scuff marks. Use the ATF soaked # 600 paper to polish off any burrs that are on the valve, then wash the valve in solvent and dry it with compressed air.

4. Roll up half a sheet of ATF-soaked # 600 paper and insert it in the valve bore of the sticking valve.

Twist the paper slightly, so that it unrolls and fits the bore tightly, then polish the bore by twisting the paper as you push it in and out.

NOTE: The valve body is aluminum and doesn't require much polishing to remove any burrs.

5. Remove the # 600 paper. Thoroughly wash the entire valve body in solvent, then dry it with compressed air.

6. Coat the valve with ATF, then drop it into its bore. It should drop to the bottom of the bore under its own weight. If not, repeat step 4, then retest. If the valve still sticks, replace the valve body.

7. Remove the valve, and thoroughly clean it and the valve body with solvent. Dry all parts with compressed air, then reassemble using ATF as a lubricant.

Valve Body Valve Installation

1. Coat all parts with ATF before assembly.

2. Install the valves and springs in the sequence shown for the main valve body, regulator valve body, and servo body. Refer to the following valve cap illustrations, and install each valve cap so the end shown facing up will be facing the outside of the valve body.

3. Install all the springs and seats. Insert the spring (A) in the valve, then install the valve in the valve body (B). Push the spring in with a screwdriver, then install the spring seat (C).

Main Valve Body Disassembly, Inspection, and Reassembly
