2003 FORD F750 transmission

Use only a lubricant that meets Ford specifications (refer toLubricant
specificationsin thischapter).
Use of a non-approved rear axle lubricant may cause internal axle
component damage.
Check your rear axle lubricant level using the following procedure:
1. Park the vehicle on level ground.
2. Set the parking brake and shift into N (Neutral) (automatic
transmission) or 1 (First) (manual transmission) and turn the engine off.
3. Clean any dirt from around the rear axle filler plug.
4. Remove the filler plug and inspect the lubricant level.
5. The lubricant level should be up to the bottom of the filler plug
opening.
6. If necessary, add enough lubricant through the filler plug opening so
that the lubricant level is at the bottom of the opening.
7. Clean and install the filler plug securely.
Drain and refill your rear axle lubricant using the following procedure:
1. Drain the rear axle while the lubricant is warm.
2. Park the vehicle on level ground.
3. Set the parking brake and shift into N (Neutral) (automatic
transmission) or 1 (First) (manual transmission) and turn the engine off.
4. Clean any dirt from around the rear axle filler and drain plugs.
5. Remove the filler and drain plugs and drain the lubricant into a
suitable container. Dispose all used automotive fluids in a responsible
manner following your local authorized standards.
6. Clean and install the drain plug securely.
7. Add enough lubricant through the filler plug opening so that the
lubricant level is up to the bottom of the opening.
8. Clean and install the filler plug securely.

maintenance on all designated items to achieve best vehicle operation.
Scheduled maintenance beyond 160 930 km (100 000 miles) should be
continued as before 160 930 km (100 000 miles).
SPECIAL OPERATING CONDITIONS
If your driving habitsfrequentlyinclude one or more the following
conditions:
•Short trips oflessthan 16 km (ten miles) when outside temperatures

service.
•High speed operation with a fully loaded vehicle (max. GVW).
•Snowplowing.
Perform the following:
•Change engine oil and oil filter every three months, 8 000 km (5 000
miles) or 125 hours of engine service.
•If operating in severe dust conditions, replace the air cleaner filter
more often than regular intervals as determined by the air filter
restriction indicator. Make sure that the air filter restriction indicator
is in good working order.
•Lube the manual transmission and the rear axle every 48 279 km
(30 000 miles) or 6 months, whichever comes first.
•See the Allison, Cummins and Caterpillar Operator’s Manual.
AIR BRAKE ADJUSTMENT

* Coolant protection checks should be made just prior to the onset of freezing weather,
where applicable. If coolant is dirty or rusty in appearance, the system should be
drained, flushed and refilled with the prescribed solution of cooling system fluid and
water. Use only permanent type coolant that meets Ford specifications ESE-M97B18-C.
See the engine manufacturer’s operating guide for supplimental corrosion inhibitor
specifications.
