I was at my dealer , the service manager said he will check my tranny fluid.
He showed me the result : a brownish liquid and according to the color
it should be changed NOW ---or else ---future problem !!

Cost for the pressurised process $ 180 for 9 liters , if the color is back to red , the process
stops there , if not satisfying they would push another 9 liters , cost : + $ 80 ,
only since the machine is already hooked-up.

My answer was I need to think before they proceed.

Back home I check the manual : change the fluid @ 100,000 kms
*** note in the book : the color of the fluid should not be used
to decide the goodness or badness of it .

The sori has now 75,000 kms .

Do they try a fast one on me ? Why discard a fluid that is still good for
another 25,000 kms .

I read that many owners start to have problem with their tranny after
this flushing procedure .

Where is the Truth ?

Thanks.

They always say to not use the color to judge the quality of the fluid. I change trans fluid every 30K miles. Probably overkill for most purposes but is relatively easy and cheap to do and thus I do not mind the extra insurance it provides.

The thing that kills transmission fluid is heat. Heat in the transmission is usually a product of driving at high RPMs, which usually means you are towing something or driving fast. Do you frequently accelerate the Sorento and rev up the RPMs? Or tow something that keeps the rpm range higher? If not you likely do not have to change it. Still if it were me and approaching 50K miles I would go ahead and do it. If you want to do it yourself you just need to get underneath and open the drain and fill plugs on the trans pan, let it drain out, clean off the drain plug, then screw it back in and run a hose down from above the motor and fill it with fluid until it comes out the fill hole. Actually very easy and much less than $180. I see absolutely no reason whatsoever you could need to go through 18 liters of fluid. That is just ridiculous. I wouldn't expect you to go through more than a gallon or slightly more with a standard drain and refill. That means two drain and refills would maybe add up to 9 total quarts of fluid used. 9 liters should be plenty. You should ask your dealer what the fluid costs just for shits.

Stupid Hyundai/Kia have not released their transmission fluid specs for third parties to make and use the trademark yet, hopefully they do eventually. Similar fluid from other manufacturers, like ATF+4 for Chrysler, runs $4-$5 / quart. That means the most you would pay for a total change would be $50 doing it yourself. And you would know that it was actually done.

The 60k mile/100k km service is for severe use. Normal service has no required service. I would make sure they are using the correct fluid, because if they were, $180 for an 9 liter exchange is a good deal. The fluid alone in the US is ~$14/qt, and I'm sure its more in Canada. It is synthetic, which is why it is so expensive.

If I were you I'd wait until 100K, or get 4 liters and do a drain and fill yourself.

Just to add , the service manager put me in guard to do NOT drain and refill
my-self ---they do better by plugging a machine , which will remove all the
crust inside the tranny :eek: he compares the drain&fill way as washing your clothes
in dirty water ----blablabla

My mind is set : I will wait till the 100,000 is done .

I will ask in an independant garage what they suggest ;)

I am a soft driver , only push the rpm occasionally , to merge when someone
refuses to give me the way :D

Thanks for your inputs.

They're just trying to drum up business. The color has no bearing on how "good" the fluid is. I'm planning to just drain and re-fill. I'll do that 3 times over the course of a week and that will effectively flush the vast majority of the old fluid out and rejuvenate the additives. I don't plan on touching it until 50-60k miles.

Best,

This is a complete line of bullshit. It has NOTHING in common with washing clothes with dirty water. The only limitation to a drain and refill is that it does not get at any of the muck in the cooling lines/torque converter. This is one reason I change my fluid at shorter intervals, it somewhat makes up for that.

A lot of transmissions like this one in the Sorento do not have a filter you can easily get to, but the drain plug is the magnet so you can still wash off the vast majority of metal shavings. Some manufacturers actually advise strongly against any type of transmission "flush" since it has a higher possibility of doing damage than helping.

Just make sure if you have an independent garage do it later that you go out and buy the right fluid, or be sure that they have the right fluid. It is not that easy to get right now and can make a big difference in the life of your transmission.

Found this article : How often should the automatic transmission fluid... — Yahoo! Autos

My question to Kia : if under regular use the ATF tends to overheat ,
why dont you add a cooler directly at the design level ?

'' Auxiliary Cooling

An auxiliary transmission fluid cooler is easy to install and can substantially lower fluid operating temperatures. The plate/fin type cooler is somewhat more efficient than the tube and fin design, but either can lower fluid temperatures anywhere from 80 to 140 degrees when installed in series with the stock unit. Typical cooling efficiencies run in the 35 to 50% range. ''

At the 3rd independant tranny specialist I called : if the color changed it is because there
was some overheat during the driving ...

Nah, the color isn't material. It will darken over time, regardless. Unless it stinks to holy hell, there really isn't a way to eyeball the fluid and know it's bad. It needs to be analyzed to see if the additive package is intact and that it's still within the correct viscosity range.

This. And also you probably don't want to just plug an auxiliary cooler on. Your transmission has an optimal operating temp and being too low is not good for it either. You would really have to monitor your transmission fluid temp to see if you really needed another cooler, and then you may want to set it up with a thermostat so that it only opens up when fluid gets hot enough.

I should pay a beer to you Guys ...just realise that the leitmotiv
of the service manager is $ :eek:

At this same visit , they pulled out all the different liquids ,
placed them in a color chart , they also pushed to change
the cooling fluid ---which they say is becoming acidic and will
''eat'' all the inside ---terrifying sales pitch.

This happened during my wait for changing rear brake rotors and pads ...
$ 590 job ---my response : my budget is blown for now.

Thanks.

I would switch dealers.

How many kilometers on your vehicle?

75,000 kms .

The previous manager was not soooo pushy , one salesman told
me they cleared him because he was too understanding to the
customers ....

Most Kia dealers around here -Montreal - Laval , went to the same
marketing school , I think customers has to be alert and say plain NO .
Not easy to find the truth , I dont mind to pay when it is needed
but refuse to go for a ride :(

On a side note : it is a trend now in all makers-dealership :
selling the superflous cares .

I would also say to find a new dealer. For $590 you could change pads/rotors/brake fluid/trans fluid/diff fluid/multiplate coupling fluid/power steering fluid/coolant/outside air filter/cabin air filter/lube weatherstripping/clean throttle body.

Some of these are super easy to do and some take a tiny bit of work. None are difficult to do. I do all my preventative maintenance well ahead of schedule because I do it all myself and that makes it very inexpensive to do. That price is really high though and if you're paying prices like that I would find somewhere else to go or learn to do it yourself.

LOL. Your engine coolant is good for 5 years. I usually replace mine a little early at about 4 years. This dealership sounds like one to be avoided.

Ah ...right , and no kidding it is the largest in Canada !!!

The owner has Hyunday - Mazda - Ford .

There is some kind of monopoly in the area , I had called in another
kia dealer for my brakes ---it was even higher : $ 630 , and $ 590 at
the independant with napa parts.

On a side note : gas is now $ 1.39 per liter :lol:

A few things:

1) At 46,000 miles, your tranny fluid should be fine. Unless you're doing severe driving, it's good for another 54,000 miles! Kia doesn't give you a dip stick to check your tranny fluid, and they claim it's a sealed system that needs NO SERVICE OR EVEN INSPECTION until 100,000 miles, your powertrain warranty is 100k miles, so, don't worry about your transmission, Kia doesn't even want you to. Your dealer is full of it.

2) Surprising you'd need rear rotors after only 46k miles. Even fronts would be surprising, rear, VERY surprising. I would have at least tried to get that done under warranty.

Kia is taking us for a ride in Canada ...the powertrain waaranty is in KM ...
100,000 kms = 62,000 miles ....I complaint to Canada headquarter before
buying , they reply the features-build-specs---are different for the canadian
market :eek:

Even Kia Europe gives longer warranty ... 7 years.

Kia international gives LESS for granted customers ...shame on you :p

As for the brakes = absolutely no warranty on wear.

Thanks.

There is no warranty on wear, however, as megalobyte indicated, 46,000 is far too few kilometers especially for rear brakes. The front do most of the breaking. With my last car and the one before, I had changed the front twice before needing to do anything to the rear.

It must be one of two things: 1) there is something else wrong with the brakes such as a problem with the calipers. This then caused the issue and should be fixed no charge under warranty, OR 2) the dealer was taking you for a ride.

Ask other mechanics and see what they say. Look around on the web.

I've seen this before, dealers taking advantage of customers. It only takes one to give them all a bad reputation. If you find a good one, treat them well and with respect. However, it doesn't hurt to get a second opinion.

Vim , I have to agree with you ---though it is too late.
I double checked with an independant mechanic and he did not
give me a logic explanation ---just that the rear brakes were overdue ,
his cost - oem parts - was the same price as the dealer .

The dealer explained me that because I did not have the brakes checked
in the last 2 years , then it is my fault ...some grease was missing ---whatever the explanation I found their view as un-professionnal.

That is why I like this forum as the first best opinion ;)

Thanks.

Rust was most likely the cause. It causes the pads the hang up in the brackets and not slide, leading to uneven pad wear and early wearout. Pad wear from rust would not be warranty. If a caliper seized, then it should be covered.
