I have an 07 XLT 4x4 autotragic encroaching on the 100k mark. Due to being furloughed from my job for the past year and a half, maintenance other than oil and filter has been neglected. Im now back to work and making money again.

Things to do:

Flush transmission

Change t-case fluid

Front and rear diff fluid

P/S Fluid

Flush radiator

Change thermostat

Plugs and wires

Fuel Filter

Clean MAF

PCV valve

Anything else I should do?

For no maintenance, I have had zero problems and get 22mpg highway. Ford is the new honda IMO. Its starting to feel sluggish and has a higher idle on start up. Transmission gets goofy sometimes but with 100k on the fluid Im surprised it still shifts. I put that lucas transmission fluid stuff in when she starts to shift hard and she returrns to buttery smooth shifting.

 

Looks like a good list. Don't forget air filter (duh), transmission filter, and bleeding the brakes couldn't hurt but probably isn't a big deal.

 

I have a k and N air filter. I bled the brakes recently and I will probably have the stealership flush the tranny which I assume will come with a filter. Dropping the tranny pan is a little more involvement than I care to take on at this point.

 

Usually when a shop flushes a transmission they just pull a hose off of the cooler and pump the old out, and the new in.

 

Taking the pan off isn't hard at all to be honest. Its about 12 bolts or so and then you drain it, pull the filter off put the new one on (dont forget the o rings) and slap the pan back on. Doesn't take more than an hour.
