8. Reinstall the engine cover and snap it down securely

onto the four mounting studs.

9. Check for leaks. Release the parking brake.

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.
