GENERAL INFORMATION
41TE FOUR SPEED AUTOMATIC TRANSAXLE
The 41TE four-speed FWD transaxle uses fully-
adaptive controls. Adaptive controls are those which
perform their functions based on real-time feedback
sensor information. The transaxle uses hydraulically
applied clutches to shift a planetary gear train.
TRANSAXLE IDENTIFICATION
The 41TE transaxle identification code is printed
on a label. The label is located on the transaxle case
next to the solenoid assembly (Fig. 1).

GENERAL INFORMATION
POWER TRANSFER UNIT
The Power Transfer Unit (P.T.U.) is attached to a
modified automatic transaxle case where the right
half shaft extension housing would normally be
located. The Transfer Unit provides the power to the
rear wheels through a hypoid ring gear and pinion
set.
The Power Transfer Unit is sealed from the tran-
saxle and has its own oil sump. The Unit uses SAE
85W-90 gear lubricant and holds 1.15 liters (1.22
quarts).
The Power Transfer Unit fill plug is located on the
end cover (Fig. 1).Do not mistake the black plas-
tic inspection plug located on the P.T.U. case
for the fill plug.Service of the Power Transfer Unit is limited to:
²Seals
²Gaskets
²One ball bearing
²Output flange
If the ring gear and pinion, any tapered roller
bearings, case, covers, or pinion carrier fail the entire
unit must be replaced.
DIAGNOSIS AND TESTING
SEAL IDENTIFICATION
For accurate seal diagnosis, repair seal name and
location is critical. Refer to (Fig. 2), (Fig. 3), (Fig. 4)
and (Fig. 5) for correct seal name and location.

(2) Use a pry bar to remove seal from retainer
plate (Fig. 21). Be careful not to damage seal journal
when removing seal.
INSTALLATION
(1) Using a large socket, carefully install new seal.
The spring side of the seal must face the transaxle
differential.
(2) Reinstall the P.T.U. into the vehicle.(3) Check and fill fluids as required.
REAR COVER O-RING
REMOVAL
(1) Raise vehicle on hoist.
(2) Remove rear cover retaining bolts (Fig. 22).
(3) Index rear cover to the case for later reassem-
bly (Fig. 23).
(4) Pull rear cover out of the P.T.U. case (Fig. 24).
(5) Remove rear cover O-Ring (Fig. 25).
INSTALLATION
(1) To install, reverse removal procedure.
POWER TRANSFER UNIT OUTPUT SEAL
The power transfer unit must be removed from the
vehicle to replace this seal.

(6) Remove output flange nut (Fig. 29).
(7) Index the pinion to the flange (Fig. 30).
(8) Using a hydraulic press, press off output flange
from pinion.
(9) Use a hammer and chisel to remove output
seal (Fig. 31).
CAUTION: If the output flange requires replace-
ment, a new shim may be required. Refer to Output
Flange Shim Selection procedure in this section to
determine correct shim requirements.
INSTALLATION
(1) Install new seal with Seal Installer 5049 (Fig.
32).
(2) If the original flange is used, align index marks
and press flange onto pinion. If a new flange is used
disregard the alignment marks on the pinion and
press flange onto the pinion.(3) Install flange nut and tighten to 244 N´m (180
ft. lbs.).

INSTALLATION
(1) Use bearing driver L-4530 and handle C-4171-2
to install bearing (Fig. 55).
(2) Install bearing retaining snap ring.
CAUTION: When installing bearing retaining snap
ring, be sure to index the snap ring so that the
snap ring does not cover bearing oil passage.
(3) Install new outer half shaft seal using
MD998334 seal installer (Fig. 56).Do not reuse the
old seal.
(4) Reinstall right front half shaft.
(5) Check and fill fluids as required.

DESCRIPTION AND OPERATION
TIRE INFORMATION
Tires are designed and engineered for each specific
vehicle. They provide the best overall performance
for normal operation. The ride and handling charac-
teristics match the vehicle's requirements. With
proper care they will give excellent reliability, trac-
tion, skid resistance, and tread life.
Driving habits have more effect on tire life than
any other factor. Careful drivers will obtain, in most
cases, much greater mileage than severe use or care-
less drivers. A few of the driving habits which will
shorten the life of any tire are:
²Rapid acceleration
²Severe application of brakes
²High-speed driving
²Taking turns at excessive speeds
²Striking curbs and other obstacles
Radial ply tires are more prone to irregular tread
wear. It is important to follow the tire rotation inter-
val shown in the section on Tire Rotation. This will
help to achieve a greater tread-life potential.
TIRE IDENTIFICATION
Tire type, size, aspect ratio and speed rating are
encoded in the letters and numbers imprinted on the
side wall of the tire. Refer to the chart to decipher
the tire identification code (Fig. 1).
Performance tires will have a speed rating letter
after the aspect ratio number. The speed rating is not
always printed on the tire sidewall. The letterSindi-
cates that the tire is speed rated up to 112 mph.
²Qup to 100 mph
²Tup to 118 mph
²Uup to 124 mph
²Hup to 130 mph
²Vup to 149 mph
²Zmore than 149 mph (consult the tire manu-
facturer for the specific speed rating)
An All Season type tire will have eitherM+S,M
&SorM±S(indicating mud and snow traction)
imprinted on the side wall.
TIRE CHAINS
This vehicle was designed to allow the use of a
specified type of snow chain on the tires. Only com-
pact snow chains or other traction aidsmeeting SAE
type ªClass Sº specifications may be used.Any style
