The fluid level should be between the bottom of 

the fill hole and a point not more than 3/16 of 

an inch (4.76 mm) below the bottom of the

Under normal operating conditions, the fluid 

installed at the factory will give satisfactory 

lubrication for the life of the vehicle. If the fluid 

becomes contaminated with water, it should be 

changed immediately. Otherwise, change the 

fluid as recommended in the Maintenance Plan

Special Additives

It is strongly recommended against using any 

special additives in the transmission. Automatic 

Transmission Fluid (ATF) is an engineered 

product and its performance may be impaired 

by supplemental additives. Therefore, do not 

add any fluid additives to the transmission. 

Avoid using transmission sealers as they may 

adversely affect seals.
