Automatic transmission fluid
Checking the fluid level
The automatic transmission fluid exp and s larg ely as its temp erature
rises; the fluid level d iffers ac c ord ing to fluid t emp erature. Therefore,
there are two d ifferent sc ales for c hec king the lev el of hot fluid and
c old fluid on the d ip stic k.
Thoug h the fluid level c an b e c hec ked without warmi ng up the fluid
on the “COLD ” sid e, we rec ommend c hec king the fluid level when t he
fluid is at op erating temp erature. n Checking the fluid level when the fluid is hot
Chec k the fluid level monthly.
1. Drive the vehic le several miles to raise the temp erature of the
transmission fluid up to normal op erating temp eratu re; 140 to 176F
(60 to 80 C) is normal.
2. Park the vehic le on a level surfac e and set the p arking b rake.
3. First shift the selec tor lever in eac h p osition. Then shift it in the “P ”
p osition, and run the eng ine at id ling sp eed .
