Fluid Level Check
Check the fluid level by removing the fill plug. The fluid
level should be between the bottom of the fill hole and a
point not more than 3/16” (4.76 mm) below the bottom of
the hole.
Add fluid, if necessary, to maintain the proper level.
Lubricant Selection
Use only manufacturer’s recommended manual trans-
mission fluid. Refer to “Fluids, Lubricants, and Genuine
Parts” in this section for the correct fluid type.
Frequency of Fluid Change
Under normal operating conditions, the fluid installed at
the factory will give satisfactory lubrication for the life of
the vehicle. Fluid changes are not necessary unless the
fluid becomes contaminated with water. Change the fluid
immediately if contaminated with water.
NOTE: Be sure to follow the “trailer tow, snow plow,
heavy load, taxi, police, commercial service, off-road,
desert, or sustained high speeds during hot weather”
maintenance interval if applicable.
