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.

TRANSAXLE
DESCRIPTION
The 41TE (Fig. 1) is a four-speed transaxle that is
a conventional hydraulic/mechanical assembly with
an integral differential, and is controlled with adap-
tive electronic controls and monitors. The hydraulic
system of the transaxle consists of the transaxle
fluid, fluid passages, hydraulic valves, and various
line pressure control components. An input clutch
assembly which houses the underdrive, overdrive,
and reverse clutches is used. It also utilizes separate
holding clutches: 2nd/4th gear and Low/Reverse. The
primary mechanical components of the transaxle con-
sist of the following:
²Three multiple disc input clutches
²Two multiple disc holding clutches
²Four hydraulic accumulators
²Two planetary gear sets
²Hydraulic oil pump
²Valve body
²Solenoid/Pressure switch assembly
²Integral differential assemblyControl of the transaxle is accomplished by fully
adaptive electronics. Optimum shift scheduling is
accomplished through continuous real-time sensor
feedback information provided to the Powertrain
Control Module (PCM) or Transmission Control Mod-
ule (TCM).
The PCM/TCM is the heart of the electronic control
system and relies on information from various direct
and indirect inputs (sensors, switches, etc.) to deter-
mine driver demand and vehicle operating condi-
tions. With this information, the PCM/TCM can
calculate and perform timely and quality shifts
through various output or control devices (solenoid
pack, transmission control relay, etc.).
The PCM/TCM also performs certain self-diagnos-
tic functions and provides comprehensive information
(sensor data, DTC's, etc.) which is helpful in proper
diagnosis and repair. This information can be viewed
with the DRB scan tool.

TRANSAXLE IDENTIFICATION
The 41TE transaxle is identified by a barcode label
that is fixed to the transaxle case as shown in (Fig.
2).The label contains a series of digits that can be
translated into useful information such as transaxle
part number, date of manufacture, manufacturing
origin, plant shift number, build sequence number,
etc. Refer to (Fig. 3) for identification label break-
down.

TORQUE CONVERTER LEAKAGE
Possible sources of torque converter leakage are:
²Torque converter weld leaks at the outside diam-
eter weld (Fig. 8).
²Torque converter hub weld (Fig. 8).
REMOVAL
NOTE: If transaxle assembly is being replaced or
overhauled (clutch and/or seal replacement), it is
necessary to perform the TCM Quick Learn Proce-
dure. (Refer to 8 - ELECTRICAL/ELECTRONIC CON-
TROL MODULES/TRANSMISSION CONTROL
MODULE - STANDARD PROCEDURE)
(1) Disconnect battery cables.
(2) Remove battery shield (Fig. 9).
(3) Remove coolant recovery bottle (Fig. 10).
(4) Remove fluid level indicator/tube assembly.
Plug opening to prevent debris from entering trans-
axle.
(5) Using a blade or suitable hose cutter, cut trans-
axle oil cooler lines off flush with fittings. Plug lines
and fittings to prevent debris from entering transaxle
or cooler circuit. A service splice kit will be installed
upon reassembly.
(6) Disconnect input and output shaft speed sensor
connectors (Fig. 11).
(7) Disconnect transmission range sensor (TRS)
connector (Fig. 11).
(8) Disconnect solenoid/pressure switch assembly
connector (Fig. 11).
