2006 SUBARU LEGACY automatic transmission fluid

8-28 Driving tips
sary, use 1st gear) in order to utilize the
engine braking effect and prevent over-
heating of your vehicle’s brakes. Do not
make sudden downshifts. yWhen driving uphill in hot weather, the
air conditioner may turn off automatically
to protect the engine from overheating. y When driving uphill in hot weather, pay
attention to the water temperature gauge
pointer (for all vehicles) and AT OIL TEMP
warning light (for AT vehicles) since the
engine and transmission are relatively
prone to overheating under these condi-
tions. If the water temperature gauge
pointer approaches the OVERHEAT zone
or the AT OIL TEMP warning light illumi-
nates, immediately switch off the air con-
ditioner and stop the vehicle at the nearest
safe place. Refer to the “Engine overheat-
ing” section in chapter 9, and “Warning
and indicator lights” section in chapter 3.
NOTE
With AT vehicles, the temperature of
engine coolant is less likely to rise to
the OVERHEAT zone in the “D” posi-
tion than in the manual mode position. y If your vehicle has an automatic trans-
mission, avoid using the accelerator pedal
to stay stationary on an uphill slope in-
stead of using the parking brake or foot
brake. That may cause the transmission fluid to overheat. T
Parking on a grade
Always block the wheels under both vehi-
cle and trailer when parking. Apply the
parking brake firmly. You should not park
on a hill or slope. But if parking on a hill or
slope cannot be avoided, you should take
the following steps:
1. Apply the brakes and hold the pedal
down.
2. Have someone place wheel blocks un-
der both the vehicle and trailer wheels.
3. When the wheel blocks are in place, re-
lease the regular brakes slowly until the
blocks absorb the load.
4. Apply the regular brakes and then ap-
ply the parking brake; slowly release the
regular brakes.
5. Shift into 1st or reverse gear (manual
transmission) or “P” (automatic transmis-
sion) and shut off the engine.

Automatic transmission fluid „Checking the fluid level
The automatic transmission fluid expands
largely as its temperature rises; the fluid
level differs according to fluid tempera-
ture. Therefore, there are two different
scales for checking the level of hot fluid
and cold fluid on the dipstick.
Though the fluid level can be checked
without warming up the fluid on the
“COLD” range, we recommend checking
the fluid level when the fluid is at operating
temperature. T Checking the fluid level when the
fluid is hot
Check the fluid level monthly.
1. Drive the vehicle se veral miles to raise
the temperature of the transmission fluid
up to normal operating temperature; 158 to 176 °F (70 to 80 °C) is normal.
2. Park the vehicle on a level surface and
set the parking brake.
3. First shift the selector lever in each po-
sition. Then shift it in the “P” position, and
run the engine at idling speed. 4-speed automatic transmission
1) Yellow handle
5-speed automatic transmission
1) Yellow handle1) HOT range
2) COLD range
3) Upper level
4) Lower level
4. Pull out the dipstick and check the fluid
level on the gauge. If it is below the lower
level on the “HOT” range, add the recom-
mended automatic transmission fluid up to
the upper level. T Checking the fluid level when the
fluid is cold
When the fluid level has to be checked
without time to warm up the automatic
transmission, check to see that the fluid
level is between the lower level and upper
level on the “COLD” range. If it is below
that range, add fluid up to the upper level.
Be careful not to overfill.1

NOTE
Using any non-specified type of auto-
matic transmission fluid could result in
damage inside the transmission. When
replacing the automatic transmission
fluid, be sure to use the kind specified
above. Front differential gear oil (AT

Checking the oil level
1) Yellow handle
1. Park the vehicle on a level surface and
stop the engine.
2. Pull out the dipstick, wipe it clean, and
insert it again. 1) Upper level
2) Lower level
3. Pull out the dipstick again and check
the oil level on it. If it is below the lower
level, add oil to bring the level up to the up-
per level.Be careful not to spill automatic
transmission fluid when adding it. If
automatic transmission fluid touch-
es the exhaust pipe, it may cause a
bad smell, smoke, and/or a fire. If au- tomatic transmissi on fluid gets on
the exhaust pipe, be sure to wipe it
off.
