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 - 41TE TRANSAXLE
GENERAL DIAGNOSIS
NOTE: Before attempting any repair on a 41TE four-
speed automatic transaxle, check for diagnostic
trouble 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-

(32) Install the transfer shaft gear using Tool 6261
(Fig. 121).
CAUTION: Install a NEW retaining nut, as the origi-
nal nut MUST NOT be reused.
(33) Install the new retaining nut and washer.
(34) Using Tool 6259, torque transfer gear retain-
ing nut to 271 N´m 200 ft. lbs.) (Fig. 122).(35) Measure transfer shaft end play.Transfer
shaft end play should be within 0.05-0.10 mm
(0.002-0.004 in.).If the end play is too high, install a
0.04 mm (0.0016 in.) thicker shim. If the end play is
too low, install a 0.04 mm (0.0016 in.) thinner shim.
Repeat until 0.05-0.10 mm (0.002-0.004 in.) end play
is obtained.
