SHIFT COVER
DESCRIPTION
The shift cover assembly (Fig. 274) (Fig. 275) is
operated by the gearshift crossover and selector
cables, and operates the shift fork/shaft system. It
consists of crossover and selector lever mechanisms,
transaxle vent, a main shift selector shaft, and the
5-R blockout mechanism. The shift cover is only ser-
viced as an assembly.

SHIFT FORK AND SHAFT
DESCRIPTION
The T850 utilizes a unique shift fork and shaft
arrangement consisting of three shift forks and two
shafts as shown in (Fig. 276). This system is oper-
ated by the shift cover assembly, which combined
with a unique gearshift cable design, offers a higher
mechanical advantage over traditional shift systems.
This arrangement results in less friction and lower
shift cable loads for smoother, more positive opera-
tion. The shift fork assemblies are constructed of
brass, float about the shafts with the aid of needle
bearings, and are serviced only as fork/bearing
assemblies.
SYNCHRONIZER
DESCRIPTION
The T850 transaxle uses two styles of synchronizer
assemblies; a conventional single-cone style is used
for the 5th/Reverse and 3rd/4th applications (Fig.
277), and a dual-cone style for the 1st/2nd gear appli-
cation (Fig. 278).
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:
²Teeth, for wear, scuffed, nicked, burred, or bro-
ken teeth
²Keys, for wear or distortion
²Balls 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 work bench.
Hub is non-directional.
(2) Install springs into hub slot.
(3) Insert key into hub and spring.
(4) Apply petroleum jelly to the hole in the key.
Insert balls into each key.
(5) Slide sleeve over the hub and depress balls as
you carefully slip the sleeve into position.
VEHICLE SPEED SENSOR
REMOVAL
(1) Raise vehicle on hoist.
(2) Disconnect the speed sensor connector (Fig.
279).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. 279).
(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. 279) .
(2) Using a NEW o-ring, install the speed sensor
to the transaxle (Fig. 279) .
(3) Install the bolt and torque to 7 N´m (60 in.
lbs.).
(4) Connect speed sensor connector (Fig. 279) .
(5) Lower vehicle and road test to verify proper
speedometer operation.
