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.
