Valve Body Repair

6. Remove the cooler check valve spring (L) and thecooler check 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 the 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 the ATF strainer. Install the new ones when
installing the valve bodies. 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 does not
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. 1. Coat all parts with ATF before assembly.
2. Install the valves and the springs in the sequence
shown for the main valve body (see page 14-303),
the regulator valve body (see page 14-305), and the
servo body (see page 14- 306). Refer to the
following valve cap illustrations, and install each
valvecapsotheendshownfacingupwillbefacing
the outside of the valve body.
3. Install all the springs and the 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).

NOTE: Do not hold the shift solenoid valve connector to remove and to install the shift solenoid valves. Hold
the shift solenoid valve body.
 Do not install shift solenoid valve A before installing shift solenoid valve D, and do not install shift
solenoid valve B before solenoid valve E. If solenoid
valves A and B are installed before solenoid valves D
and E, it may damage the hydraulic control system.
1. Remove the shift solenoid valves by holding the solenoid valve body.
2. Install new O-rings (two O-ring per shift solenoid valve) (F) on the shift solenoid valves.
NOTE: A new solenoid valve comes with new
O-rings. If you install a new solenoid valve, use the
O-rings provided with it.
3. Install shift solenoid valve D by holding the shift solenoid valve body; be sure to install mounting
bracket contacts the servo body.
4. Install shift solenoid valve A by holding the shift solenoid valve body; be sure to install mounting
bracket contacts the bracket on shift solenoid
valve D. 5. Install shift solenoid valve E by holding the shift
solenoid valve body; be sure to install mounting
bracket contacts the servo body.
6. Install shift solenoid valve B by holding the shift solenoid valve body; be sure to install mounting
bracket contacts the bracket on shift solenoid
valve E.
7. Install shift solenoid valve C by holding the shift solenoid valve body; be sure to install mounting
bracket contacts the servo body.

commercially available 3/8 ’’-16 slide hammer (A).
2. Install a new mainshaft bearing until it bottoms in the housing using the driver and the 62 x 68 mm
attachment. 3. Install a new oil seal flush using the housing using

NOTE: Do not drive the seal into the torque
converter housing until it bottoms out; it will block
the fluid return passage and cause transmission
damage.
