TORQUE CONVERTER
DESCRIPTION
The torque converter (Fig. 327) is a hydraulic
device that couples the engine crankshaft to the
transmission. The torque converter consists of an
outer shell with an internal turbine, a stator, an
overrunning clutch, an impeller and an electronically
applied converter clutch. The converter clutch pro-
vides reduced engine speed and greater fuel economy
when engaged. Clutch engagement also provides
reduced transmission fluid temperatures. The con-
verter clutch engages in third gear. The torque con-
verter hub drives the transmission oil (fluid) pump.
The torque converter is a sealed, welded unit that
is not repairable and is serviced as an assembly.
CAUTION: The torque converter must be replaced if
a transmission failure resulted in large amounts of
metal or fiber contamination in the fluid. If the fluid
is contaminated, flush the fluid cooler and lines.

is requested when the TCM pulses this signal to
ground. The PCM recognizes this request and
responds by retarding ignition timing, killing fuel
injectors, etc. The PCM sends a confirmation of the
request to the TCM via the communication bus.
Torque reduction is not noticable by the driver, and
usually lasts for a very short period of time.
If the confirmation signal is not received by the
TCM after two sequential request messages, a diag-
nostic trouble code will be set.
VALVE BODY
DESCRIPTION
The valve body assembly consists of a cast alumi-
num valve body, a separator plate, and transfer
plate. The valve body contains valves and check balls
that control fluid delivery to the torque converter
clutch, solenoid/pressure switch assembly, and fric-
tional clutches. The valve body contains the following
components (Fig. 340):
²Regulator valve
²Solenoid switch valve
²Manual valve²Converter clutch switch valve
²Converter clutch control valve
²Torque converter regulator valve
²Low/Reverse switch valve
In addition, the valve body also contains the ther-
mal valve, #2,3&4 check balls, the #5 (overdrive)
check valve and the 2/4 accumulator assembly. (Refer
to 21 - TRANSMISSION/TRANSAXLE/AUTOMATIC
- 41TE/VALVE BODY - DISASSEMBLY)
OPERATION
NOTE: Refer to the Hydraulic Schematics for a
visual aid in determining valve location, operation
and design.
REGULATOR VALVE
The regulator valve controls hydraulic pressure in
the transaxle. It receives unregulated pressure from
the pump, which works against spring tension to
maintain oil at specific pressures. A system of sleeves
and ports allows the regulator valve to work at one of
three predetermined pressure levels. Regulated oil
pressure is also referred to as ªline pressure.º

door temperature drops. After checking the air
pressure, replace valve cap finger tight.
Inflation pressures specified on the Tire Inflation
Pressure Label are always the cold inflation pressure
of the tire. Cold inflation pressure is obtained after
the vehicle has not been operated for at least 3
hours, or the vehicle is driven less than one mile
after being inoperative for 3 hours. Tire inflation
pressures may increase from 2 to 6 pounds persquare inch (psi) (14 to 41 kPa) during operation. Do
not reduce this normal pressure buildup.
Improper inflation can cause:
²Uneven wear patterns
²Reduced tread life
²Reduced fuel economy
²Unsatisfactory ride
²The vehicle to drift.
WARNING: OVER OR UNDER INFLATED TIRES CAN
AFFECT VEHICLE HANDLING. THE TIRE CAN FAIL
SUDDENLY, RESULTING IN LOSS OF VEHICLE
CONTROL.
Under inflation causes rapid shoulder wear, tire
flexing, and can result in tire failure (Fig. 25).

ADJUSTMENTS
SLIDING DOOR ADJUSTMENTS
NOTE: For power sliding door procedures refer to
POWER SLIDING DOOR SYSTEM in the ELECTRI-
CAL section.
PRELIMINARY CHECKS
(1) Close the sliding door, visually checking C-post
striker alignment entry into latch. Striker at this
point must not affect alignment. Striker should go
straight into the latching mechanism.
(2) On vehicles with left sliding doors, check the
fuel door blocker striker entry into latch. Striker at
this point must not affect alignment.
(3) Check C-post and B-post for door to aperture
gaps and door to door gaps. All gaps should be 5 mm
  1 mm.
(4) Check door for height using character lines as
a reference. Also check roof contour as a controlling
factor.
Using the procedures noted below, adjust the side
door in the order the individual steps are called out.
DOOR FLUSHNESS ADJUSTMENT
(1) Check sliding door flushness at the C-pillar
striker.
(2) Adjust the C-pillar striker in or out until the
door is flush.
(3) Check upper B-pillar flushness to A-pillar
cover.
(4) Loosen one nut on upper hinge and adjust door
in or out until the door is flush.
(5) Check flushness at upper C-pillar.
(6) If upper C-pillar flushness is out of specifica-
tion use a heavy rubber mallet on the door assembly
until door is in specifications.
DOOR GAP ADJUSTMENT - UP/DOWN
(1) Visually inspect the sliding door for fitting low
at the top of the door by checking the alignment of
the top contour of the door to the quarter panel.
