5. INSTALL FIRST AND REVERSE BRAKE PISTON TO
TRANSMISSION CASE
(a) Coat the new O±rings with ATF.
(b) Install the 2 O±rings on the piston.
(c) Push the piston into the bore of the case, facing the spring
seat upward.
6. INSTALL PISTON RETURN SPRING
(a) Place the return spring and snap ring on the piston.
(b) Place SST, and compress the return spring evenly by
tightening the bolt gradually.
SST 09350±32014 (09351±32040)
(c) Install snap ring. Visually check to make sure it is fully
seated and centered by the 3 lugs on the spring retainer.
Be sure the end gap of snap ring is not aligned with the
spring retainer claw.
(d) Remove the SST.
7. INSTALL SNAP RING TO TRANSAXLE CASE

(b) Place the oil pump through the input shaft, and align the
bolt holes of the pump body with the transmission case.
NOTICE: Do not push on the oil pump strongly or the oil
seal ring will stick to the direct clutch drum.
Torque: 22 N´m (225 kgf´cm, 16 ft´lbf)
26. MEASURE END PLAY OF INPUT SHAFT
Measure the end play with a dial gauge.
End play:
0.25±0.90 mm (0.0098±0.0354 in.)
HINT: There are 2 different thickness bearings for end of
stator shaft. If the end play is in excess of standard, select
one of them.
Bearing thickness:
3.60 mm (0.1417 in.)
4.19 mm (0.1650 in.)
27. CHECK INPUT SHAFT ROTATION
Make sure that the input shaft rotates smoothly.
28. INSTALL SECOND COAST BRAKE PISTON
(a) Coat the new O±rings with ATF and install it to the cover.
(b) Install the outer spring with the piston.
(c) Place the cover into the bore.
(d) Using SST, install the snap ring while pressing the cover.
SST 09350±32014 (09351±32050)
(e) Check that the front end of the piston rod contacts the
center of the second brake band depression.
29. CHECK SECOND COAST BRAKE PISTON STROKE
(a) Apply a small amount of paint to the piston rod at the point
it meets the case.

DTC P0500 Vehicle Speed Sensor Malfunction
CIRCUIT DESCRIPTION
The vehicle speed sensor outputs a 4±pulse signal for every revolution of the rotor shaft, which is rotated
by the transmission output shaft via the driven gear. After this signal is converted into a more precise rectan-
gular wave form by the wave form shaping circuit inside the combination meter, it is then transmitted to the
ECM. The ECM determines the vehicle speed based on the frequency of these pluse signals.
