Automatic Transmission Fluid Change?

I took my 2010 Jeep Wrangler with automatic transmission in today for oil change and tire rotation..29,500 miles....the dealership told me I need my automatic transmisssion fluid changed (the owners manual says at 60,000 miles), that in need my front and rear differentuial fluid changed (the manual says inspect at 30,000 miles) and I need something called a Full Fuel Service. All these things total over $700 and really not required in the owners manual. I drive my Jeep to and from work, rarely put in 4 WD, don't tow any boats, or operate in dusty conditions.... do I really have to do all these things, or should I follow the maintenance schedule in the owners manual?

Oil change and differential fluid are easy to do so i do it myself.The auto transmission flush I have not done but i heard that its a cake walk. The fuel service are something you can have Jiffy lube done for alot cheaper than what the dealership charges IMHO.

Full fuel service? Huh

I bought a certified 07 w 35,500

Manual though.

I asked about the fluids since they went through the whole vehicle. Everything was checked and topped off except the oil and filter that they changed

I was a tech at an independent shop for about 10 years. These kinds of services are VERY misunderstood by both consumers AND service providers, sometimes for different reasons and sometimes for the same reasons. I'll hit them up one at a time:

Have you owned this since new? If so, you have the advantage of knowing it's history. If not, the mileage is low enough that nothing should be that bad off unless it was just hammered. Regardless, fluids should be changed based on condition instead of mileage.

Quote:

Does it say 60k miles for normal service or severe service? If it says that for normal service, you need to look up what the severe service interval is because 99.99% of all cars are used in what the manufacturer considers severe service. If it says that is the severe service interval you probably don't need it changed. Given the temperatures they tend to run at, I would not hesitate to change the fluid ofte, but I would not pay for a flush unless the fluid is absolutely nasty. Just drop the pan (and possibly replace it with one that has a drain plug) and let it drip, then change the filter, install the pan and refill. If you do that frequently there is no reason to ever flush it.

Quote:
that in need my front and rear differentuial fluid changed (the manual says inspect at 30,000 miles)
Same story as above on normal vs severe service. I would definitely do this yourself, it isn't hard. Diff fluid, particularly in the rear has a hard life. It won't hurt to change it, but I wouldn't pay to have it done.

Quote:

At your mileage I have serious doubts that you need this service. You need to find a BG Products salesman that will sell you product and buy a can of fuel system maintainer (I forget the exact name and part #) every 10k miles or so and not worry about it. The other half of the fuel service is cleaning the gunk out of the intake manifold. You can do this with a spray can of GM Top Engine Cleaner. Some people like Seafoam for this as well. Either way, you can do the service your self for a few bucks.

Save your money.

You might see what's required to preserve your warranty. Differential fluid - often isn't changed and lasts 100K+ miles. If the manual says 60K on the ATF, I wouldn't do it a whole lot sooner. Oil, on some motors when dirty clogs the oil galleries (passages), so 5K is probably reasonable. Fuel filters (if serviceable), ought to be replaced as that prolongs the life of the fuel pump. Some are located in the tank and cost prohibitive to replace. Buy an air filter and change it yourself, easy to check, easy to replace. I do almost all my own maintenance. (almost, I cannot flash the TIPM)

I just had a similar experience a few days ago....
I have 24k on my 2010...

They told me I needed the transfer case and differential oil changes...and the tranny fluid flushed. $700+ job...
I know the differential fluid should be changed as needed, I havent checked the oil myself yet but will this weekend....
The manual says the transfer case fluid should be changed at 60k if using your vehicle for any of the following: police, taxi, fleet, off-road or frequent trailer towing.

Anyway, all that said....

If I need to I will change the diff. fluids myself....
What I'd like to know is....is it a good idea to take the covers off to make sure the gears are looking OK?
Or should I just drain and refill??

Your opinions are greatly appreciated

I don't remember seeing drain plugs on the diffs. You'll have to pull the covers anyway.

You could always upgrade them to covers with drain plugs. There are plenty of options available.

If you are the original owner and do not beat on it, then your dealership is trying to rip you off. Plain and simple. I got the same crap every time I used to go to my dealership as well. I tell them I'll just follow what it says in the manual - thank you... And I do. I keep all my receipts (in case there is ever a warranty question) and do the fluids myself now.

DO NOT trust the dealership "techs" when they start double talking about this or that needing to be done. If it's not in the manual then it's BS. If they find a legitimate problem then that's a different story. I wouldn't put it past some of these ass monkeys to mess something up on purpose so they can charge to fix it. But then again, I'm very paranoid.

Follow the manual and you should have no issues. Most folks go by schedule B.

There are drain plugs on the differentials, not the covers. Very bottom right ride.

I am the original owner and do not beat up on the Jeep at all.
It's been off road only once (sad) and the axles were submerged in water twice for a few seconds. That's as rough as it's gotten other than street driving and 4wd usage in snow.

I definitely know the dealer tech's are full of it when they tell me services are needed that the maintenance schedule has listed as needing service thousands of miles later!
The first time they tried to get me to have the diff fluids changed (at 12k I think!!) I told him what the manual said. He the came back with 'Chrysler now recommends....blah blah'.
I politely declined the service.

I think I'll start doing my own oil changes/tire rotations as well.

I'll be dammed. Didn't see those at all. I didn't look very hard, I just glanced long enough to see if they were leaking (the front one was. At 500 miles) and moved on. I figure I'll just fix it myself when I put synthetic in it at 5000 miles. Maybe install some shiny covers as well.

The plugs are convenient as long as your fluid isn't contaminated. If it is you're going to have to pull the covers anyway to get is all drained out.

Guess I'll start with draining the oil and hope it's not contaminated!

Thanks all...

If you can turn a wrench you can save yourself a lot of money. Go by your local auto parts store and pick a Chilton Manuel for your year model Jeep. The Chilton will walk you through most anything you want or need to do to your jeep...Once you have done the servicing to your Jeep yourself, you know it's done right you get to know your Jeep better and all that money you saved from not going to the dealership you can now use for Mods for your Jeep.
