onto the four mounting studs.

NOTE: To prevent dirt and water from entering the
transmission after checking or replenishing fluid, make
sure that the dipstick cap is properly reseated. It is normal
for the dipstick cap to spring back slightly from its fully
seated position, as long as its seal remains engaged in the
dipstick tube.
Fluid And Filter Changes
Refer to the “Maintenance Plan” for the proper mainte-
nance intervals.
In addition, change the fluid and filter if the fluid becomes
contaminated (with water, etc.), or if the transmission is
disassembled for any reason.
Manual Transmission
Selection Of Lubricant
Use only manufacturer’s recommended manual transmis-
sion fluid. Refer to “Fluids And Lubricants” in “Technical
Specifications” for further information.
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 of an inch (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. If the fluid becomes contaminated with water,
it should be changed immediately. Otherwise, change the
fluid as recommended in the Maintenance Plan. Refer to
the “Maintenance Plan” for the proper maintenance inter-
vals.
