Impreza 2.5 RS Sedan AWD F4-2.5L SOHC (2002)
Fluid - A/T: Testing and Inspection
INSPECTION
A. Check the level of the ATF.
1. Raise the ATF temperature to 60 to 80°C (140 to 176°F) from 40 to 60°C (104 to 140°F) (when cold) by driving a distance of 5 to 10 km (3
to 6 miles).
NOTE: The level of ATF varies with fluid temperature. Pay attention to the fluid temperature when checking oil level.
2. Make sure the vehicle is level. After selecting all positions (P, R, N, D, 3, 2, 1), set the select leveler in "P" range. Measure fluid level with the
engine idling.
NOTE: After running, idle the engine for one or two minutes before measurement.
3. If the fluid level is below the center between upper and lower marks, add the recommended ATF until the fluid level is found within the
specified range (above the center between upper and lower marks). When the transmission is hot, the level should be above the center of upper
and lower marks, and when it is cold, the level should be found below the center of these two marks.
CAUTION:
^
Use care not to exceed the upper limit level.
^
ATF level varies with temperature. Remember that the addition of fluid to the upper limit mark when the transmission is cold will result in
overfilling of fluid.
4. Fluid temperature rising speed:
^
By idling the engine
Time for temperature rise to 60°C (140°F) with atmospheric temperature of 0°C (32°F): More than 25 minutes
Time for temperature rise to 30°C (86°F) with atmospheric temperature of 0°C (32°F): Approximately 8 minutes
^
By running the vehicle
Time for temperature rise to 60°C (140°F) with atmospheric temperature of 0°C (32°F): More than 10 minutes
5. Method for checking fluid level upon delivery or at periodic inspection:
Check fluid level after a warm-up run of approximately 10 minutes. During the warm-up period, the automatic transmission functions can
also be checked.
B. Check the fluid for leaks.
Check for leaks in the transmission. If there are leaks, it is necessary to repair or replace gasket, oil seals, plugs or other parts.
