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:
²
Teeth, for wear, scuffed, nicked, burred, or broken
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.

LOW/REVERSE CLUTCH
Apply air pressure to the low/reverse clutch feed
hole (rear of case, between 2 bolt holes). Then, look
in the area where the low/reverse piston contacts the
first separator plate. Watch carefully for the piston to
move forward. The piston should return to its origi-
nal position after the air pressure is removed.
UNDERDRIVE CLUTCH
Because this clutch piston cannot be seen, its oper-
ation is checked by function. Air pressure is applied
to the low/reverse and the 2/4 clutches. This locks the
output shaft. Use a piece of rubber hose wrapped
around the input shaft and a pair of clamp-on pliers
to turn the input shaft. Next apply air pressure to
the underdrive clutch. The input shaft should notrotate with hand torque. Release the air pressure
and confirm that the input shaft will rotate.
DIAGNOSIS AND TESTING - TORQUE
CONVERTER HOUSING FLUID LEAKAGE
When diagnosing converter housing fluid leaks,
three actions must be taken before repair:
(1) Verify proper transmission fluid level.
(2) Verify that the leak originates from the con-
verter housing area and is transmission fluid.
(3) Determine the true source of the leak.
Fluid leakage at or around the torque converter
area may originate from an engine oil leak (Fig. 7).
The area should be examined closely. Factory fill
fluid is red and, therefore, can be distinguished from
engine oil.
Some suspected converter housing fluid leaks may
not be leaks at all. They may only be the result of
residual fluid in the converter housing, or excess
fluid spilled during factory fill, or fill after repair.
Converter housing leaks have several potential
sources. Through careful observation, a leak source
can be identified before removing the transmission
for repair.
Pump seal leaks tend to move along the drive hub
and onto the rear of the converter (Fig. 7). Pump
o-ring or pump body leaks follow the same path as a
seal leak. Pump attaching bolt leaks are generally
deposited on the inside of the converter housing and
not on the converter itself. Pump seal or gasket leaks
usually travel down the inside of the converter hous-
ing (Fig. 7).

(25) Remove front carrier/rear annulus assembly
and #6 needle bearing (Fig. 40).
(26) Remove rear sun gear and #7 needle bearing
(Fig. 41).
NOTE: The number 7 needle bearing has three anti-
reversal tabs and is common with the number five
and number two position. The orientation should
allow the bearing to seat flat against the rear sun
gear (Fig. 42). A small amount of petrolatum can be
used to hold the bearing to the rear sun gear.(27) Setup tool 5058 as shown in (Fig. 43). Com-
press 2/4 clutch return spring (just enough to remove
snap ring) and remove snap ring.
NOTE: Verify that Tool 5058 is centered properly
over the 2/4 clutch retainer before compressing. If
necessary, fasten the 5058 bar to the bellhousing
flange with any combination of locking pliers and
bolts to center the tool properly.
