Be careful with the flush. With your mileage you are sure to have issues with the transmission. I would find a shop that will let the fluid drain naturally for a few hours and then change the filter along with the new fluid.

Rear diff and the front diff (if you have one) fluid change. Don't pump it out, I'd take the covers off, inspect, clean out, new gasket and fluid.

You said you were replacing the belt, but keep the old one as a spare.

HAVE FUN!

There isn't anything better than the stench of a road trip.

Make sure your tires, suspension, steering is in good order. Double check your coolant system that it does indeed hold @ 16psi and you do not have any leaks. You may want to ensure yourself with a overlook at the alternator and battery as well.

Have a AAA card with you at all times, hahaha. That is all I can think of right now, but I will probably add on later.

Never "Flush" a tranny, that will kill it.

When you have the belt off, check your tensioner pulley and Idler Pulley bearing for roughness.
Also with the belt off, spin the water pump to check its bearing and check for any side to side play in it.

I don't see why you should be too concerned about the trans, these are stout units. Drop the pan, replace the filters, put the pan back and re-fill the trans. You won't get the fluid that's in the torque converter, but that's not really a problem if you didn't already have a specific concern. if your 02 Overland is like mine, there's already an aux trans cooler on it.

My advice is inspect all of your suspension bushings, the repetitive jiggling of a sustained highway drive could be different enough from their daily "groove" that they finish dying at the worst time. Be sure they're in fair or better shape before you head out. If you have any vibrations or out of balance tires/etc, get that resolved before leaving. I drive commercially as a major component of my job (just drove from Phoenix to Chicago to Dallas in the past week) so the above advice comes from direct experience.

Check all your ujoints, front wheel bearings, etc. Check the spare, jack, etc. Make sure you can loosen all of your lugnuts also. It's no fun to get out in the middle of nowhere and realize that some gorilla put them on with an impact and you break your lug wrench trying to take them off. :|

Overall don't pretend something is ok if it's clearly not.

...And give us the details on the trip!!! From where to where? Why? What are your plans for stopping at attractions?????

Have a great trip! Road trips are the best.
Pete

Check spare tire pressure,
Grab 5-7 bottles of Techron and add every other tank.
Do oil change once you reach your destination.
Bring nitrile gloves for messy work.
Bring container of water, JIC.
Bring windshield washer fluid.
Have a good time!

I just changed the diff fluid and the front axle seals I toon the covers off and everything

And yeah I'm just doing a change in tranny fluid no flush

I replaced the front wheel bearings/ hubs when I did the seals

I plan on rotation and balancing the tires before i go

As for my trip I leave Virginia beach VA on June 20th and stop in TN, MO, WY, UT, and then end in oak harbor WA, I plan on rock climbing at a lot of places as we pass them other than that just drivin!

And thanks again guys for the tips anymore would be helpful if you forgot to mention something thanks again

I just took a 2700mi round trip from NY to FL in February. I brought a spare bottle of every oil/liquid that the Jeep needs, jack stand, torque wrench, and most of what everyone else is saying here. Drove perfectly, just wore out one of the front wheel bearings, and front DS u-joint. Expect some post trip maintenance.
Have a safe trip!!

Here is my plan when this tank gets down to half I'm going to put 3/4 bottle of seafoam in vac hoses then 1/2bottle in oil and whole bottle in gassed the rest of both in the gas tanks

Do the 60 plus etc etc big smoke show then drive the last half of tank and at that end first tune up starts

1 drain engine oil
2 install new spark plugs platinum
3 instal new injectors Bosch
4 fill engine with Mobil 1 full Syn with Bosch filter
5 flush coolant. And clean with cleanser and then use sealer and put it back on fill it and test it
6. If we have it install cold air intake
7 drain tranny clean and eg new gasket and filter
8 balance tires/ Tire pressure
9 clean car
10 install new exhaust if we have it

Balance all 5 tires. You never know if you'll get a flat on the Interstate! Torque all lug nuts to specs. Then check them after driving 8 hours. Highway vibration does strange things. Take extra fluid. Cheap insurance.
