What are the oil change guidelines for 2005 E-350 superduty chassis with more than 90,000 miles...the same question for the transmission fluids?

The 04 was pretty straight forward.

Change the oil and filter when the display tells you to. (Don't forget to reset Oil Life system!)
when the display tells you to change engine oil... Do the following as well:
~Lube Chassis Components
~Check Tires for Air and Damage
~Inspect Break System
~Check Engine Fluids and Washer System
~Check Power Steering System
~Check Wiper Blades
~Check Restraint System
~Lube Body Components (See manual)
~Replace Cabin Air Filter (Located in firewall on passenger side.)


Every 25K miles do the following:
~ Inspect Fuel System, Exhaust System, Accessory Drive Belts for damage or wear.
~ Replace Air Cleaner

Ever 50K Miles
~ If used for Towing - Replace Transfer Case Fluid :: If not change fluid ever 75Kk miles.

Every 100k Miles
~ Change Automatic Transmission Fluid and Filter
~ Change Automatic Transmission Fluid and Filter again at 150k if heavy service
~ Replace Spark Plugs

Every 150k miles
~ Change Engine Coolant (Or every 5 years which ever comes first!)
~ Replace Engine Accessory Drive Belt

optional y are supposed to change the transfer case fluid every 50k if towing

Ford calls for every 90,000 miles in the maintenance schedule, as a long time ford dealer tech I think that is to long, for max transmission life do the change every 60,000 miles.

TRANSMISSION FLUID AND TRANSFER CASE FLUIDS ARE SUPPOSED TO BE CHANGED EVERY 60,000 MILES. ENGINE OIL AND FILTER SHOULD BE CHANGED EVERY 3,000 MILES, THESE ARE AUTOMOTIVE INDUSTRY STANDARDS I HAVE WORKED WITH FOR 35 YEARS

Change front/rear axle oil
Change transfer case oil
Air filter
Engine coolant
Rotate tires
Fluid level on battery/radiator/brakes
Change oil and filter
Inspect for fluid leaks
Inspect coolant and heater hoses
Check exhaust system
Check drive belts/tires/wheels/brake lines
Check steering operation/disc brakes/brake pedal play
Check parking brake
Check and lube accelerator linkage
Check suspension/steering/power steering fluid
Lube body and chassis
Check TOD system fluid
Check cruise control linkage and hoses
Check starter safety switch
Lube key lock cylinder

You need to have the cam belt & water pump replaced at 110,000 miles not 90,000. You should have the transmission fluid changed, brakes & all hoses inspected. The coolant should be drained, thermostat replaced and fresh coolant installed. Of course the air & cabin filter should be replaced every 30,000 miles. The fuel filter is permanent and needs no replacing. Brake fluid should be changed unless you have already had this done. Serpentine belt replaced at 110,000 miles with the cam belt.

Use sludge protectant oils and change transmission fluid often. Do all the maintenance on time or before. Like differential fluids and etc. look in your service manual on what to do and do it in time.

USUALLY YOU SHOULD CHANGE THE TRANY FLUID EVERY 40,000 MILES. MORE OFTEN IF YOU LIVE IN A HOT AREA LIKE PHOENIX ARIZONA. YOU COULD HAVE PROBLEMS IF YOU CHANGE THE FLUID NOW. IT IS KIND OF A GAMBLE. IF YOU HAVEN'T DRIVEN YOUR CAR HARD YOU MORE THAN LIKELY WILL BE FINE. A GOOD INDICATOR OF THE OVERALL CONDITION IS TO CHECK THE FLUID AND DETERMINE HOW BURNED THE FLUID HAS BECOME. GOOD LUCK.

Well, I'm not really sure what the manufacturer's recommended interval is... But to be honest with you, once every 100000 kms, or 5-6 years is plenty for a transmission fluid/filter change is enough (yes, there is a filter inside the pan of the transmission, assuming it's an automatic). But, if you notice problems earlier (transmission starting to slip, fluid discoloration, or any other transmission related driveability issues) the first thing to do would be to do a transmission oil/filter change as soon as you can. Beware of these places that offer a transmission flush, that's about as useful as putting winter air in your tires, and costs money for nothing.
