Automatic transmission fluid
& Checking the fluid level
The automatic transmission fluid expands
largely as its temperature rises; the fluid
level differs according to fluid temperature.
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, it is recommended to
check the fluid level when the fluid is at
operating temperature.
! Checking the fluid level when the
fluid is hot
1. Drive the vehicle several miles to raise
the temperature of the transmission fluid
up to normal operating temperature; 158
to 176
8F (70 to 808C) is normal.
2. Park the vehicle on a level surface and
set the parking brake.
3. First shift the selector lever in each
position. Then shift it in the
“P” position,
and run the engine at idling speed.

1) HOT range
2) COLD range
3) Upper level
4) Lower level
