TORQUE CONVERTER CLUTCH (TCC)
In a standard torque converter, the impeller and
turbine are rotating at about the same speed and the
stator is freewheeling, providing no torque multipli-
cation. By applying the turbine's piston to the front
cover's friction material, a total converter engage-
ment can be obtained. The result of this engagement
is a direct 1:1 mechanical link between the engine
and the transmission.
The engagement and disengagement of the TCC
are automatic and controlled by the Powertrain Con-
trol Module (PCM). The engagement cannot be acti-
vated in the lower gears because it eliminates the
torque multiplication effect of the torque converter
necessary for acceleration. Inputs that determine
clutch engagement are: coolant temperature, vehicle
speed and throttle position. The torque converter
clutch is engaged by the clutch solenoid on the valve
body. The clutch will engage at approximately 56
km/h (35 mph) with light throttle, after the shift to
third gear.
REMOVAL
(1) Remove transmission and torque converter
from vehicle. (Refer to 21 - TRANSMISSION/TRANS-
AXLE/AUTOMATIC - 41TE - REMOVAL)
(2) Place a suitable drain pan under the converter
housing end of the transmission.
CAUTION: Verify that transmission is secure on the
lifting device or work surface, the center of gravity
of the transmission will shift when the torque con-
verter is removed creating an unstable condition.
The torque converter is a heavy unit. Use caution
when separating the torque converter from the
transmission.
(3) Pull the torque converter forward until the cen-
ter hub clears the oil pump seal.
(4) Separate the torque converter from the trans-
mission.
INSTALLATION
Check converter hub and drive notches for sharp
edges, burrs, scratches, or nicks. Polish the hub and
notches with 320/400 grit paper or crocus cloth if nec-
essary. The hub must be smooth to avoid damaging
the pump seal at installation.
(1) Lubricate converter hub and oil pump seal lip
with transmission fluid.
(2) Place torque converter in position on transmis-
sion.
CAUTION: Do not damage oil pump seal or bushing
while inserting torque converter into the front of the
transmission.(3) Align torque converter to oil pump seal open-
ing.
(4) Insert torque converter hub into oil pump.
(5) While pushing torque converter inward, rotate
converter until converter is fully seated in the oil
pump gears.
(6) Check converter seating with a scale and
straightedge (Fig. 326). Surface of converter lugs
should be 1/2 in. to rear of straightedge when con-
verter is fully seated.
(7) If necessary, temporarily secure converter with
C-clamp attached to the converter housing.
(8) Install the transmission in the vehicle. (Refer
to 21 - TRANSMISSION/TRANSAXLE/AUTOMATIC
- 41TE - INSTALLATION)
(9) Fill the transmission with the recommended
fluid. (Refer to 21 - TRANSMISSION/TRANSAXLE/
AUTOMATIC - 41TE/FLUID - STANDARD PROCE-
DURE)TRANSMISSION CONTROL
RELAY
DESCRIPTION
The transmission control relay (Fig. 327) is located
in the Intelligent Power Module (IPM), which is
located on the left side of the engine compartment
between the battery and left fender.

(2) Install regulator valve spring retainer (Fig.
354).
(3) Install dual retainer plate using Tool 6301 (Fig.
355).(4) Verify that all retainers are installed as shown
in (Fig. 356). Retainers should be flush or below
valve body surface.
(5) Install check balls into position as shown in
(Fig. 357). If necessary, secure them with petrolatum
or transmission assembly gel for assembly ease.

INPUT SHAFT
DESCRIPTION
The input shaft assembly (Fig. 1) is part of the
transaxle geartrain, is driven by the clutch assembly,
and consists of the following components: ² Input Mainshaft
² 3rd Speed Gear
² 4th Speed Gear
² 3/4 Synchronizer
² 5th Input Gear
The input shaft meshes with the intermediate
shaft, and is supported by a needle bearing at the
front of the transaxle, and a sealed roller bearing at
the rear of the transaxle.
DISASSEMBLY
NOTE: When servicing the input shaft assembly, all
snap rings which are removed MUST be replaced
with new snap rings upon reassembly. The 5th gear
nut must be replaced also.
(1) Invert input shaft assembly and place in fix-
ture 8487. (2) Remove input bearing snap ring (Fig. 2).
(3) Remove input bearing. Place input shaft
assembly onto arbor press table, with the input bear-
ing supported by bearing splitter (Fig. 3). Using
adapter 8486-4, press bearing off of shaft, while
helper supports shaft to prevent dropping. (4) Place input shaft assembly back into fixture
8487. Secure fixture to bench with fasteners, or
secure to bench vise.
