CAUTION

!

 

When replacing pressure control solenoid 
valve and/or TCC pressure control solenoid 
valve, it is strictly required to replace it 
together with valve body assembly as a set. 
Replacing pressure control solenoid valve 
and/or TCC pressure control solenoid valve 
independently may cause excessive shift 
shock.

 

1) Measure inside diameter of transmission case 

bushing. If inside diameter exceeds limit, replace 
transmission case.

Transmission case bushing inside diameter 
standard
38.113 – 38.138 mm (1.5005 – 1.5015 in.)

2) After applying A/T fluid to new O-rings, install them 

to reverse brake piston (3), reaction sleeve (2) and 
secondary reverse piston (1).

3) Measure free length of reverse brake piston return 

spring.

Standard free length of reverse brake piston 
return spring
16.84 mm (0.663 in.)

4) Install reverse brake piston assembly and brake 

piston return spring to transmission case, using care 
not to damage O-ring. Then install snap ring (1) with 
special tools.

NOTE

• Install so that opening in snap ring (1) will 

not align with any of 3 lugs of spring seat.

• Do not compress spring more than 

necessary and do not allow it fall or tilt.

 

Special tool
:  09926–98320
(B):  09926–98390 
(C):  09944–88210 

5) Prepare a stand as shown. It is necessary because 

work will be done with transmission case (1) set 
upright from this step on.

NOTE

• To protect transmission case against 

damage, spread cloth on stand where case 
contacts.

• A stand of such size as shown in the figure 

will facilitate work.
