Changing A/T FluidECS00FWD
1. Warm up ATF.
2. Stop engine.
3. Loosen level gauge bolt.
4. Remove A/T fluid level gauge.
5. Remove drain plug and drain ATF from drain hole.
6. Install drain plug gasket and drain plug to oil pan.
CAUTION:
Do not reuse drain plug gasket.
7. Tighten drain plug to the specified torque. Refer toAT-218,
"COMPONENTS".
8. Refill with new ATF. Always refill same volume with drained ATF.
lTo replace the ATF, pour in new ATF at A/T fluid charging pipe
with the engine idling and at the same time drain the old ATF
from A/T fluid cooler hose return side.
lWhen the color of the ATF coming out is about the same as the color of the new ATF, the replacement
is complete. The amount of new ATF to use should be 30 to 50% increase of the specified amount.
CAUTION:
lUse only Genuine NISSAN ATF Matic Fluid J. Do not mix with other ATF.
lUsing ATF other than Genuine NISSAN ATF Matic Fluid J will cause deterioration in driveability
and A/T durability, and may damage the A/T, which is not covered by the NISSAN new vehicle
warranty.
lWhen filling ATF, take care not to spillover heat generating parts such as exhaust.
9. Run engine at idle speed for 5 minutes.
10. Check A/T fluid level and condition. Refer toAT-12, "
Checking A/T Fluid". If ATF is still dirty, repeat step 2
through 9.
11. Install the removed A/T fluid level gauge into A/T fluid charging pipe.
12. Tighten level gauge bolt to the specified torque. Refer toAT- 2 4 7 , "

A/T FLUID
Checking A/T Fluid
ECS00FWE
1. Warm up engine.
2. Check for A/T fluid leakage.
3. Loosen level gauge bolt.
4. Before driving, A/T fluid level can be checked at A/T fluid tem-
peratures of 30 to 50°C (86 to 122°F) using “COLD” range on A/
T fluid level gauge as follows.
a. Park vehicle on level surface and set parking brake.
b. Start engine and move selector lever through each gear posi-
tion. Leave selector lever in “P” position.
c. Check A/T fluid level with engine idling.
d. Remove A/T fluid level gauge and wipe clean with lint-free
paper.
CAUTION:
When wiping away A/T fluid level gauge, always use lint-
free paper, not a cloth one.
e. Reinsert A/T fluid level gauge into A/T fluid charging pipe as far as it will go.
CAUTION:
To check A/T fluid level, insert A/T fluid level gauge until the cap contacts the end of A/T fluid
charging pipe, with 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 ATF to A/T fluid
charging pipe.
CAUTION:
Do not overfill.
5. Drive vehicle for approximately 5 minutes in urban areas.
6. Make the A/T fluid temperature approximately 65°C(149°F).
NOTE:
A/T fluid level will be greatly affected by temperature as shown in figure. Therefore, be certain to
perform operation while checking data with CONSULT-II.
a. Connect CONSULT-II to data link connector. Refer toAT-79, "
CONSULT-II SETTING PROCEDURE".
b. Select “MAIN SIGNALS” in “DATA MONITOR” mode for “A/T” with CONSULT-II.
c. Readthevalueof“ATFTEMP1”.
7. Recheck A/T fluid level at A/T fluid temperatures of approximately 65°C(149°F)using“HOT”rangeonA/
T fluid level gauge.

TCM FunctionECS00FWI
The function of the TCM is to:
lReceive input signals sent from various switches and sensors.
lDetermine required line pressure, shifting point, lock-up operation, and engine brake operation.
lSend required output signals to the respective solenoids.
CONTROL SYSTEM OUTLINE
The A/T senses vehicle operating conditions through various sensors or signals. It always controls the opti-
mum shift position and reduces shifting and lock-up shocks.

A/T CONTROL SYSTEM
CAN Communication
ECS00FWJ
SYSTEM DESCRIPTION
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only. For details, refer toLAN-30,
"CAN Communication Unit".
Input/Output Signal of TCMECS00FWK
*1: Spare for vehicle speed sensor·A/T (revolution sensor)
*2: Spare for accelerator pedal position signal
*3: If these input and output signals are different, the TCM triggers the fail-safe function.
*4: Used as a condition for starting self-diagnosis; if self-diagnosis are not started, it is judged that there is some kind of error.
*5: Input by CAN communications.
*6: Output by CAN communications.Control itemLine
