Manual Transmission
Fluid Level Check
This fluid level can be checked by removing the filler
plug. If the level of the lubricant is more than 1/4” (6.4
mm) below the bottom of the filler hole while the vehicle
is on level ground, enough lubricant should be added to
bring the level to the bottom of the filler hole.
Lubricant Selection NV-3500 (5-Speed Manual
Transmission — If Equipped)
This transmission is filled with manual transmission
fluid at the factory. This fluid does not require periodic
changing. If it is necessary to add or change fluid in this
transmission refer to Recommended Fluids, Lubricants
and Genuine Parts for correct fluid type. This is the only
lubricant recommended for use in the NV-3500 transmis-
sion.
Lubricant Selection Getrag 238 (6-Speed Manual
Transmission — If Equipped)
This transmission is filled with manual transmission
fluid at the factory. This fluid does not require periodic
changing. If it is necessary to add or change fluid in this
transmission refer to Recommended Fluids, Lubricants
and Genuine Parts for correct fluid type. This is the only
lubricant recommended for use in the Getrag 238 trans-
mission.
Lubricant Selection NV-4500 (5-Speed Manual
Transmission — If Equipped)
This transmission does not require periodic changing. If
it becomes necessary to add or change the fluid in this
transmission, refer to Recommended Fluids, Lubricants
and Genuine Parts for correct fluid type.

Lubricant Selection Getrag G56 (6-Speed Manual
Transmission — If Equipped)
This transmission is filled with manual transmission
fluid at the factory. This fluid does not require periodic
changing. If it is necessary to add or change fluid in this
transmission refer to Recommended Fluids, Lubricants
and Genuine Parts for correct fluid type. This is the only
lubricant recommended for use in the Getrag G56 trans-
mission.
Automatic Transmission
Fluid Level Check
The fluid level should be checked when the engine is
fully warmed up and the fluid in the transmission is at
normal operating temperature. Operation of the trans-
mission with an improper fluid level will greatly reduce
the life of the transmission and of the fluid. Check the
fluid level whenever the vehicle is serviced.
Fluid Level Check – 45RFE/545RFE
Check the fluid level while the transmission is at normal
operating temperature 82°C (180°F). This occurs after at
least 15 miles (25 km) of driving. At normal operating
temperature the fluid cannot be held comfortably be-
tween the fingertips.
To check the automatic transmission fluid level properly,
the following procedure must be used:
1. Operate the engine at idle speed and normal operating
temperature.
2. The vehicle must be on level ground.
3. Fully apply the parking brake and press the brake
pedal.
4. Place the gear selector momentarily in each gear
position ending with the lever in P (Park).

At Each Stop for Fuel
•Check the engine oil level about 5 minutes after a fully
warmed engine is shut off. Checking the oil level while
the vehicle is on level ground will improve the accu-
racy of the oil level reading. Add oil only when the
level is at or below the ADD or MIN mark.
•Check the windshield washer solvent and add if
required.
Once a Month
•Check tire pressure and look for unusual wear or
damage.
•Inspect the battery and clean and tighten the terminals
as required.
•Check the fluid levels of coolant bottle, brake master
cylinder, and transmission and add as needed.
•Check all lights and all other electrical items for correct
operation.
At Each Oil Change
•Change the engine oil filter.
•Lubricate Drivetrain/Steering/Suspension Grease Fit-
tings (if equipped)
•Inspect the exhaust system.
•Inspect the brake hoses.
•Inspect the CV joints (if equipped) and front suspen-
sion components.
•Check the automatic transmission fluid level.
•Check the manual transmission fluid level.
•Check the coolant level, hoses, and clamps.
