ON-VEHICLE SERVICE (JR405E) 7A3-3
Cold Level
The vehicle must not have been driven so that the
temperature reaches around 20
C (68
F) before the
cold level check is made.
1. Park the vehicle on a level surface.
2. Apply the parking brake firmly.
3. Start the engine and allow it to warm up.
The engine coolant temperature gauge needle
should be midway between the “C” mark and “H”
mark.
4. Let the engine run at idle.
Move the select lever slowly through all the gea
r
ranges.
Stop in each range just long enough for the
transmission to engage.
5. Return the select lever either “P” or “N”.
6. Remove the ATF level dipstick.
7. Wipe the dipstick clean with a paper towel.
8. Reinsert the dipstick and wait several seconds.

9. Remove the dipstick.
The ATF level should be inside the “C”range on the
dipstick.
If the ATF level is below the “C” range, ATF must be
added.
242R300002


ATF CHANGE
1. Start the engine and allow it to idle until the ATF
reaches a temperature of 40-50
C
2. Park the vehicle on level ground and block the
wheels.
3. Stop the engine.
4. Raise vehicle and support with suitable safety
stands.
5. Remove the drain plug from the oil pan and drain the
ATF (approximately 6 liters).
6. Remove the oil pan.
7. Inspect the oil pan (details written below).
8. Install the oil pan.
Note:
Use new gasket. Clean the oil pan and magnet.
Oil pan bolt torque : 8 Nm (69 lbin)
9. Replace the gasket and install the drain plug.
Drain plug torque : 35 Nm (26 lbft)
Note:
Do not reuse old washer (gasket).
Clean the drain plug (especially the threaded section).
10. Pour about 5 liters of new ATF. Then, add more ATF
carefully as necessary using the dipstick.
Refer to “ATF LEVEL” previously in this section.
Note:
Keep the engine idle (do not stop it) during the oil level
adjustment.
11. Remove the safety stands and wheel blocks. Inspect
1. Check the drain plug tip for adhesion of foreign
substances.
2. Check the drained ATF for color, smell and inclusion
of foreign substances.
3. Check the oil pan bottom and magnet for adhesion o
f
foreign substances.
If a problem is discovered during those checks, the
Automatic transmission must be overhauled.
Note:
The torque converter and the oil strainer need replaced
with new ones if the drained ATF contains large
amounts of metallic or facing flakes.
In addition, flush the ATF cooler circuit
