A/T fluid level will be greatly affected by temper ature as shown in figure. Therefore, be certain to
perform operation while checki ng data with CONSULT-III.
a. Connect CONSULT-III to data link connector.
b. Select “MAIN SIGNALS” in “DATA MONITOR” mode for “TRANSMISSION” with CONSULT-III.
c. Read out the value of “ATF TEMP 1”.
7. Recheck A/T fluid level at A/T 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 A/T fluid level, inser t the A/T fluid level gauge
until the cap contacts the en d of the A/T fluid charging
pipe, with the A/T fluid level gauge reversed from the nor-
mal attachment conditions as shown.
8. Check A/T fluid condition.  If ATF 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-13
(for
VQ35DE) or CO-40
(for VK45DE) and AT-13, "A/T Fluid
Cooler Cleaning".
9. Install the removed A/T fluid level gauge in the A/T fluid charging pipe.
10. Tighten level gauge bolt.

• Check for the correct installation status prior to removal or disassembly. If matching marks are required, becertain they do not interfere with the function of the parts when applied.
 Overhaul should be done in a clean work area, it is preferable to work in dustproof area.
 Before disassembly, using steam or white gasoline, completely remove sand and mud from the exterior of
the unit, preventing them from entering into the unit during disassembly or assembly.
 Check appearance of the disassembled parts for dam age, deformation, and unusual wear. Replace them
with a new ones if necessary.
 Gaskets, seals and O-rings should be replaced any time when the unit is disassembled.
 In principle, tighten bolts or nuts gradually in several steps working diagonally from inside to outside. If tight-
ening sequence is specified, observe it.
 Clean and flush the parts sufficiently and blow-dry them.
 Be careful not to damage sliding surfaces and mating surfaces.
 When applying sealant, remove the old sealant from t he mounting surface; then remove any moisture, oil,
and foreign materials from the application and mounting surfaces.
 Always use shop paper for cleaning the inside of components.
 Avoid using cotton gloves or shop rags to prevent entering of lint.
 During assembly, observe the specified tightening tor que, and apply new gear oil, petroleum jelly, or multi-
purpose grease as specified for each vehicle, if necessary.

CAUTION:
 If it becomes necessary to start the engine with a booster battery and jumper cables, use a 12-volt
booster battery.
 After connecting battery cables, ensure that they are tightly clamped to battery terminals for good
contact.
METHODS OF PREVENTING OVER-DISCHARGE
The following precautions must be taken to prevent over-discharging
a battery.
 The battery surface (particularly its top) should always be kept clean and dry.
 The terminal connections should be clean and tight.
 At every routine maintenance, check the electrolyte level.
This also applies to batteries designated as “low maintenance” and
“maintenance-free”.
 When the vehicle is not going to be used over a long period of time, disconnect the battery cable from the negative terminal.
 Check the charge condition of the battery. Periodically check the specific gr avity of the electrolyte. Keep a
close check on charge condition to prevent over-discharge.
CHECKING ELECTROLYTE LEVEL
WARNING:
Never allow battery fluid to come in contact with skin, eyes, fabrics, or painted surfaces. After touch-
ing a battery, never touch or rub your eyes until you have thoroughly washed your hands. If acid con-
tacts eyes, skin or clothing, immediately flush wit h water for 15 minutes and seek medical attention.

 Do not reuse transfer fluid, once it has been drained.
 Check the fluid level or replace the fluid only with the vehicle parked on level ground.
 During removal or installation, keep inside of transfer clear of dust or dirt.
 Replace all tires at the same time. Always use tires of the proper size and the same brand and pattern. Fit-
ting improper size and unusual wear tires applies excessive force to vehicle mechanism and can cause lon-
gitudinal vibration.
 Disassembly should be done in a clean work area, it is preferable to work in dustproof area.
 Before proceeding with disassembly, thoroughly clean the tr ansfer. It is important to prevent the internal
parts from becoming contaminated by dirt or other foreign matter.
 All parts should be carefully cleaned with a general purpose, non-flammable solvent before inspection or
reassembly.
 Check for the correct installation status prior to remo val or disassembly. If matching marks are required, be
certain they do not interfere with t he function of the parts when applied.
 Check appearance of the disassembled parts for dam age, deformation, and unusual wear. Replace them
with a new ones if necessary.
 Gaskets, seals and O-rings should be replaced any time when the transfer is disassembled.
 In principle, tighten bolts or nuts gradually in several steps working diagonally from inside to outside. If tight-
ening sequence is specified, use it.
 Observe the specified torque when assembling.
 Clean and flush the parts sufficiently and blow-dry them.
 Be careful not to damage sliding surfaces and mating surfaces.
 Clean innerparts with lint-free cloth or towels. Do not use cotton work gloves and rags to prevent adhering
fibers.
