Checking A/T FluidNCS001JJ
1. Warm up engine.
2. Check for A/T fluid leakage.
3. Loosen the 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 the A/T fluid level gauge, always use
lint-free paper, not a cloth one.
e. Re-insert 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 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 ATF to the 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 to GI-38, "
CONSULT-II Start Procedure" .
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 A/T fluid level at A/T fluid temperatures of approximately 65°C (149°F) using “HOT” range on A/
T fluid level gauge.
