the oil to drain back into the oil pan, and recheck the level. Top off the oil at this time to the fill mark.
If the vehicle is not resting on level ground, the oil level reading on the dipstick may be slightly off. Be
sure to check the level only when the car is sitting level.
10. Drain your used oil in a suitable container for recycling and clean−up your tools, as you will be
needing them again in a couple of thousand more miles (kilometers).

FLUID RECOMMENDATION

The lubricant in the transmission should be checked and changed periodically, except when the vehicle has
been operated in deep water and water has entered the transmission. When this happens, change the lubricant
in the transmission as soon as possible. Use Standard Transmission Lube SAE 80 in the Mitsubishi 5−speed
transmission, and Mercon in the Mazda M5OD transmission.

LEVEL CHECK

The fluid level should be checked every six months or 6000 miles (9600 km), whichever comes first.
1. Park the truck on a level surface, turn the engine OFF, FIRMLY apply the parking brake and block
the drive wheels.
Ground clearance may make access to the transmission filler plug impossible without raising and
supporting the vehicle, BUT, if this is done, the truck MUST be supported at four corners and level. If
only the front or rear is supported, an improper fluid level will be indicated. If you are going to place
the truck on four jackstands, this might be the perfect opportunity to rotate the tires as well.
2. Remove the filler plug from the side of the transmission case using a
extension. The fluid level should be even with the bottom of the filler hole.
3. If additional fluid is necessary, add it through the filler hole using a siphon pump or squeeze bottle.
4. When you are finished, carefully install the filler plug, but DO NOT overtighten it and damage the
housing.
DRAIN & REFILL
Under normal conditions, the manufacturer feels that manual transmission fluid should not need to be
changed. However, if the truck is driven in deep water (as high as the transmission casing) it is a good idea to
replace the fluid. Little harm can come from a fluid change when you have just purchased a used vehicle,
especially since the condition of the transmission fluid is usually not known.
If the fluid is to be drained, it is a good idea to warm the fluid first so it will flow better. This can be
accomplished by 15−20 miles of highway driving. Fluid which is warmed to normal operating temperature
will flow faster, drain more completely and remove more contaminants from the housing.
1. Drive the vehicle to assure the fluid is at normal operating temperature.
2. Raise and support the vehicle securely on jackstands. Remember that the vehicle must be supported
level (usually at four points) so the proper amount of fluid can be added.
