2015 FORD F750 Transmission

Additives and Chemicals
This owner’s manual and the Ford Workshop Manual list the
recommended additives and chemicals for your vehicle. We do not
recommend using chemicals or additives not approved by us as part of
your vehicle’s normal maintenance. Please consult your warranty
information.
Oils, Fluids and Flushing
In many cases, fluid discoloration is a normal operating characteristic
and, by itself, does not necessarily indicate a concern or that the fluid
needs to be changed. However, a qualified expert, such as the
factory-trained technicians at your dealership, should inspect discolored
fluids that also show signs of overheating or foreign material
contamination immediately.
Make sure to change your vehicle’s oils and fluids at the specified
intervals or in conjunction with a repair. Flushing is a viable way to
change fluid for many vehicle sub-systems during scheduled
maintenance. It is critical that systems are flushed only with new fluid
that is the same as that required to fill and operate the system or using a
Ford-approved flushing chemical.
