Selection of Lubricant
Use only manufacturer’s recommended manual trans-
mission fluid. Refer to “Fluids, Lubricants, and Genuine
Parts” in this section for the correct fluid type.
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 in (4.76 mm) below the bottom
of the hole.
Add fluid, if necessary, to maintain the proper level.
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
lubricant has become contaminated with water. If con-
taminated with water, the fluid should be changed
immediately.

Fluid Level Check
The fluid level should be to the bottom edge of the fill
hole (A) when the vehicle is in a level position.
