SYNCHRONIZER
DISASSEMBLY
Place synchronizer in a clean shop towel and wrap.
Press on inner hub. Carefully open up shop towel
and remove springs, balls, keys, hub, and sleeve.
CLEANING
CLEAN
Do not attempt to clean the blocking rings in sol-
vent. The friction material will become contaminated.
Place synchronizer components in a suitable holder
and clean with solvent. Air dry.
INSPECTION
INSPECT
Proper inspection of components involve:
• Teeth, for wear, scuffed, nicked, burred, or bro-
ken teeth
• Keys, for wear or distortion
• Balls and springs, for distortion, cracks, or wear
If any of these conditions exist in these compo-
nents, replace as necessary.
ASSEMBLY
(1) Position synchronizer hub onto a suitable hold-
ing fixture (input shaft). The synchronizer hubs are
directional. The hubs must be installed with the U
facing upward.
(2) Install springs into hub slot (Fig. 145).
(3) Insert key into hub and spring.
(4) Apply petroleum jelly to the hole in the key.
Insert balls into each key (Fig. 146).

VEHICLE SPEED SENSOR
DESCRIPTION
VEHICLE SPEED SENSOR
The Vehicle Speed Sensor (VSS) is a pulse genera-
tor mounted to an adapter near the transmission out-
put shaft. The sensor is driven through the adapter
by a speedometer pinion gear. The VSS pulse signal
to the speedometer/odometer is monitored by the
PCM speed control circuitry to determine vehicle
speed and to maintain speed control set speed.
REMOVAL
(1) Raise vehicle on hoist.
(2) Disconnect the speed sensor connector (Fig.
149).
CAUTION: Clean area around speed sensor before
removing to prevent dirt from entering the transaxle
during speed sensor removal.
(3) Remove speed sensor retaining bolt (Fig. 149).
(4) Remove speed sensor from transaxle.

CAUTION: Carefully remove vehicle speed sensor
so that sensor drive gear does not fall into trans-
axle. Should sensor drive gear fall into the trans-
axle during sensor removal, drive gear must be
reattached to sensor.
(5) Remove speed sensor drive gear from speed
sensor.
INSTALLATION
(1) Install pinion gear to speed sensor (Fig. 149).
(2) Using a NEW o-ring, install the speed sensor
to the transaxle (Fig. 149).
(3) Install the bolt and torque to 7 N·m (60 in.
lbs.).
(4) Connect speed sensor connector (Fig. 149).
(5) Lower vehicle and road test to verify proper
