41TE AUTOMATIC
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 body²Solenoid/Pressure switch assembly
²Integral differential assembly
Control 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.
If the tag is not legible or missing, the ªPKº num-
ber, which is stamped into the transaxle case behind
the transfer gear cover, can be referred to for identi-
fication. This number differs slightly in that it con-
tains the entire transaxle part number, rather than
the last three digits.
OPERATION
Transmission output is directed to an integral dif-
ferential by a transfer gear system in the following
input-to-output ratios:
First...............................2.84 : 1
Second.............................1.57 : 1
Third..............................1.00 : 1
Overdrive...........................0.69 : 1
Reverse............................2.21 : 1
DIAGNOSIS AND TESTING
DIAGNOSIS AND TESTING - 4XTE TRANSAXLE
GENERAL DIAGNOSIS
NOTE: Before attempting any repair on a 4XTE four-
speed automatic transaxle, check for diagnostic trou-
ble codes (DTC's) using the DRB scan tool. Refer to
the Transmission Diagnostic Procedures Manual.
Transaxle malfunctions may be caused by these
general conditions:
²Poor engine performance
²Improper adjustments
²Hydraulic malfunctions
²Mechanical malfunctions
²Electronic malfunctions
Diagnosis of these problems should always begin
by checking the easily accessible variables: fluid level
and condition, gearshift cable adjustment. Then per-
form a road test to determine if the problem has been
corrected or that more diagnosis is necessary. If the
problem persists after the preliminary tests and cor-
rections are completed, hydraulic pressure checks
should be performed.

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 con-
verter itself. Pump seal or gasket leaks usually travel
down the inside of the converter housing (Fig. 7).
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 ªQuick-Learnº Procedure.
(Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL
MODULES/TRANSMISSION CONTROL MODULE -
STANDARD PROCEDURE)
(1) Disconnect battery cables.
(2) Remove battery shield (Fig. 9).
