PRECAUTIONS
Revision: 2004 November 2004 FX35/FX45
Precautions ACS002L6
Before connecting or disconnecting the A/T assembly har-
ness connector, turn ignition switch “OFF” and disconnect
the battery cable from the negative terminal. Because bat-
tery voltage is applied to TCM even if ignition switch is
turned “OFF”.
After performing each TROUBLE DIAGNOSIS, perform
“DTC (Diagnostic Trouble Code) Confirmation Procedure”.
If the repair is completed the DTC should not be displayed
in the “DTC Confirmation Procedure”.
Always use the specified brand of ATF. Refer to MA-12, "Fluids and Lubricants" .
Use paper rags not cloth rags during work.
After replacing the ATF, dispose of the waste oil using the methods prescribed by law, ordinance, etc.
Before proceeding with disassembly, thoroughly clean the outside of the transmission. It is important to
prevent the internal parts from becoming contaminated by dirt or other foreign matter.
Disassembly should be done in a clean work area.
Use lint-free cloth or towels for wiping parts clean. Common shop rags can leave fibers that could interfere
with the operation of the transmission.
Place disassembled parts in order for easier and proper assembly.
All parts should be carefully cleaned with a general purpose, non-flammable solvent before inspection or
reassembly.
Gaskets, seals and O-rings should be replaced any time the transmission is disassembled.
It is very important to perform functional tests whenever they are indicated.
The valve body contains precision parts and requires extreme care when parts are removed and serviced.
Place disassembled valve body parts in order for easier and proper assembly. Care will also prevent
springs and small parts from becoming scattered or lost.
Properly installed valves, sleeves, plugs, etc. will slide along bores in valve body under their own weight.
Before assembly, apply a coat of recommended ATF to all parts. Apply petroleum jelly to protect O-rings
and seals, or hold bearings and washers in place during assembly. Do not use grease.
Extreme care should be taken to avoid damage to O-rings, seals and gaskets when assembling.
After overhaul, refill the transmission with new ATF.
When the A/T drain plug is removed, only some of the fluid is drained. Old A/T fluid will remain in torque
converter and ATF cooling system.
Always follow the procedures under “Changing A/T Fluid” in the AT section when changing A/T fluid. Refer
to AT- 1 2 , "
Changing A/T Fluid" , AT- 1 2 , "Checking A/T Fluid" .

e. Re-insert A/T fluid level gauge into A/T fluid charging pipe as far as it will go.
CAUTION:
To check fluid level, insert the A/T fluid level gauge until the cap contacts the end of the A/T fluid
charging pipe, with the A/T fluid level gauge reversed from the normal attachment conditions.
f. Remove A/T fluid level gauge and note reading. If reading is at low side of range, add fluid to the A/T fluid
charging pipe.
CAUTION:
Do not overfill.
5. Drive vehicle for approximately 5 minutes in urban areas.
6. Make the fluid temperature approximately 65°C (149°F).
NOTE:
Fluid level will be greatly affected by temperature as shown in the figure. Therefore, be certain to
perform level check operation checking warm up condition with CONSULT-II.
a. Connect CONSULT-II to data link connector.
b. Select “MAIN SIGNALS” in “DATA MONITOR” mode for “A/T” with CONSULT-II.
c. Read out the value of “ATF TEMP 1”.
7. Re-check fluid level at fluid temperatures of approximately 65°C (149°F) using “HOT” range on A/T fluid
level gauge.
CAUTION:
When wiping away the A/T fluid level gauge, always use lint-free paper, not a cloth one.
To check fluid level, insert the A/T fluid level gauge until
the cap contacts the end of the A/T fluid charging pipe,
with the gauge rotated from the normal attachment condi-
tions as shown.
8. Check fluid condition.
If fluid is very dark or smells burned, check operation of A/T.
Flush cooling system after repair of A/T.
If ATF contains frictional material (clutches, bands, etc.),
replace radiator and flush cooler line using cleaning solvent
and compressed air after repair of A/T. Refer to CO-14,
"RADIATOR" (for VQ35DE) or CO-39, "RADIATOR" (for
VK45DE) and AT- 1 4 , "
A/T Fluid Cooler Cleaning" .
9. Install the removed A/T fluid level gauge in the A/T fluid charging pipe.

FUNCTION OF ATF PRESSURE SWITCH
Input clutch control valveWhen the input clutch is coupled, adjusts the line pressure to the optimum pressure
(input clutch pressure) and supplies it to the input clutch. (In 4th and 5th gears, adjusts
the clutch pressure.)
Direct clutch control valveWhen the direct clutch is coupled, adjusts the line pressure to the optimum pressure
(direct clutch pressure) and supplies it to the direct clutch. (In 2nd, 3rd, and 4th gears,
adjusts the clutch pressure.)
TCC control valve
TCC control plug
TCC control sleeveSwitches the lock-up to operating or released. Also, by performing the lock-up operation
transiently, lock-up smoothly.
Torque converter lubrication valveOperates during lock-up to switch the torque converter, cooling, and lubrication system
oil path.
Cool bypass valve Allows excess oil to bypass cooler circuit without being fed into it.
Line pressure relief valve Discharges excess oil from line pressure circuit.
N-D accumulator Produces the stabilizing pressure for when N-D is selected.
Manual valveSends line pressure to each circuit according to the select position. The circuits to which
the line pressure is not sent drain. Name Function
Name Function
ATF pressure switch 1 (FR/B)Detects any malfunction in the front brake hydraulic pressure. When it detects any mal-
function, it puts the system into fail-safe mode.
ATF pressure switch 2 (LC/B)Detects any malfunction in the low coast brake hydraulic pressure. When it detects any
malfunction, it puts the system into fail-safe mode.
ATF pressure switch 3 (I/C)Detects any malfunction in the input clutch hydraulic pressure. When it detects any mal-
function, it puts the system into fail-safe mode.
ATF pressure switch 5 (D/C)Detects any malfunction in the direct clutch hydraulic pressure. When it detects any mal-
function, it puts the system into fail-safe mode.
ATF pressure switch 6 (HLR/C)Detects any malfunction in the high and low reverse clutch hydraulic pressure. When it
detects any malfunction, it puts the system into fail-safe mode.

DESCRIPTION
General
The variable compressor is basically a swash plate type that changes piston stroke in response to the required
cooling capacity.
The tilt of the wobble (swash) plate allows the piston′s stroke to change so that refrigerant discharge can be
continuously changed from 14.5 to 184 cm
3 (0.885 to 11.228 cu. in).
