COMPONENTS

DISASSEMBLY

1. Remove solenoids.




a. Remove timing solenoid.
b. Remove O-ring from solenoid.




c. Remove shift solenoid A, shift solenoid B, line pressure solenoid and look-up solenoid.
d. Remove O-rings from solenoids.

2. Remove solenoid body.




a. Place lower body facedown and remove bolts.
Be careful not to drop solenoid body.




b. Place upper body face down, and remove solenoid body with separator gaskets and separator plate.
c. Remove separator gaskets, separator plate and oil filter from solenoid body.

3. Disassemble upper and lower bodies.




a. Place lower body facedown, and remove bolts, reamer bolts and support plate.




b. Position upper body downward. Remove lower body with separator plate and separator gasket attached to upper body.







c. Remove oil filter, separator gaskets and separator plate from upper body.




d. Check to see that steel balls are properly positioned in upper body and then remove them from upper body.

NOTE: Refer to "Control Valve Upper Body" before continuing with inspection.


INSPECTION

Separator plates



- Check to make sure that separator plate is free of damage and not deformed and oil holes are clean.

Oil filter



- Check to make sure that filter is not clogged or damaged.

Timing solenoid



- Measure resistance - Refer to "Electrical Components inspection".
Testing and Inspection

4-unit Solenoid Assembly (Line pressure solenoid, lock-up solenoid and shift solenoids A and B)



- Check that filter is not clogged or damaged (line pressure solenoid and lock-up solenoid).
- Measure resistance of each solenoid - Refer to "Electrical Components inspection".
Testing and Inspection


Fluid temperature sensor



- Measure resistance - Refer to "Electrical Components inspection".

ASSEMBLY
1. Assemble upper and lower bodies.



a. Place oil circuit of upper body face up. install steel balls in their proper positions.




b. Install upper body separator gasket, separator plate and lower body separator gasket on upper body.




c. Fit oil filter and install lower body on upper body.




d. Temporarily assemble lower and upper bodies, using reamer bolt as a guide.
Be careful not to dislocate or drop steel balls and oil filter.

2. Install solenoid body on control valve body.




a. Fit oil filter and install solenoid body separator gaskets and - separator plate on solenoid body.




b. Install solenoid body on control valve body and temporarily tighten bolts.




c. Install accumulator support plate and harness clips in their proper locations, and tighten all bolts.
