Automatic transmission fluid
J 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 differ-
ent 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 rec-
ommend checking the fluid level when the fluid is at
operating temperature.
B Checking the fluid level when the fluid is hot
Check the fluid level monthly.
1. Drive the vehicle several miles to raise the tem-
perature of the transmission fluid up to normal oper-
ating temperature; 158 to 176°F (70 to 80°C) is nor-
mal.
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 id-
ling speed.
