2011 - Lower Transmission to Complete Flush

[Rodraid]

I took my 2011, AISIN transmission, in for a transmission fluid flush and the service tech told me they had to "lower" the transmission to complete the flush the fluid. They used 12 quarts so I asked why so many because the manual states it only holds 8.66 quarts. They said the rest is flushed through the transmission.

Has anyone else been told they have to lower the transmission to complete the flush & fill?

Not a lot of Genesis owners have had their transmission fluid flushed/changed since the service interval is 100,000 miles with the synthetic transmission fluid.

Is there some reason why the fluid needs to be flushed, rather than just changed (or is there a difference)?

I believe when they do a flush they remove all of the old transmission fluid versus a drain and fill only removes a portion of the old fluid. Please correct me if I am wrong.

My two previous cars I put over 200,000 miles on each and they both ran without any real problems. I do change all of the fluids a little earlier than the manual as you can see with the transmission fluid in my Genesis. I change the oil every 6,000-6,500 miles so I am not super conservative but since I want it to last over 200,000 I do change the fluids. The cost was $315 so not that bad. I will probably change it again around 140,000.

I just thought it was odd they had to remove the transmission to complete the job.

I do the same regarding changing transmission fluid. No problems here and I now have over 162,000 miles on my 2011 Genesis 4.6 V8.

I was asking whether the owner's manual specified a transmission fluid change, or a flush. I think it depends on the design of the transmission as to how much old fluid remains after a drain and fill, as opposed to a flush.

Newer transmissions designed to use synthetic oil, simply do not need to have the fluid changed as often as in the "old days." On my previous car with conventional fluid, I changed it every 30K miles as specified in the owners manual.

The manual doesn't state flush or drain. Under normal driving conditions it just says inspect but for severe driving conditions change the fluid every 60,000 miles. I live in DFW and usually don't drive during rush hour but there are times I'm stuck in traffic. That is the only part of the severe driving schedule I would fall under but for $315 why not.

Change is same as "drain and fill" as opposed to flush. I had forgotten that they changed the "fluid change" interval from 100K miles to "never" for normal driving after 2009. That is just another indication how much longer synthetic fluid lasts.

I think you are being paranoid about whether you fall into severe driving conditions. I don't think that getting stuck in traffic occasionally qualifies you.

As to "why not" change the fluid as a precaution? It would be OK if I was certain that they did it correctly. I suspect that even Hyundai dealer techs don't do it very often, and I cannot even get my dealer to change the oil correctly.

I agree synthetic fluid last longer but I'm not a believer in lifetime fluids.

Sad truth is I agree with you about suspect of the dealer techs and their abilities but that is another story. That is one reason I had them change it at 70,000 miles because I have 30,000 left on the power train warranty and I'm sure if they didn't do the job properly I will know before the warranty is up. Next time around I will just cross my fingers or hope the same guy does it. Service guy did say they had their top guy complete the job. Maybe they also realize this is something not many have a lot of experience with or he was just blowing smoke.

Don't know about this service. But I can say for sure that a fluid "flush" will keep your transmission alive much longer. We had a fleet of Ford trucks and Aerostar minivans years back. The Aerostars were notorious for blowing transmissions out by 60k miles. Our techs moved over to a fluid flush every 30k miles. They just plugged a machine into the cooling lines at the radiator. Never removed the pan or changed the filter. The transmission then lasted to 250k miles when we would sell the vans off. These were work trucks and used hard. So it makes a big difference.

It seems strange they would need to lower the transmission though. I have seen many fluid flushes and they almost always just use a machine at the cooling lines. Even when dropping the pan, the techs would use a method to get the fluid from the converter by running the engine. I never watched but sort of understood what they were doing. Nobody ever dropped a trans unless it had a problem. Maybe the Genesis unit is sealed?

The transmission in question is an Aisin 6-speed used on the 2009-2011 Genesis V6. Aisin was a joint venture of Toyota and Borg Warner to make RWD transmissions used by Lexus and other automakers.

You simply cannot compare this to a transmission from years ago. It difficult to change the fluid on the newer transmissions for the reason that they do not need to have fluid changes as often as the "old days" and apparently it is even harder to do a flush.

Viewing the world through a rear-view mirror can cause distortions of the real world as it exists today.

Thank you for a very incorrect statement. All transmissions including this one use cooling lines. Most shops have machines that connect to the cooling lines and flush them. Call around. Do a little checking. It's common to use the system. In everything from Mercs to Ford to Toyota etc. This is so very common. My brother owns one of the largest service providers in the mid west. They service all the time like this. Even hybrids.

The only thing that has changed is materials (they are better now) fluids are better and the electronics. But they all still use cooling lines and the fluid in an auto is all still flushed the same basic process. Even "sealed" units are done this way.

There was a study by Ford about 10 years ago that found most trans failures occurred from dealers wiping out the pans with a rag during filter changes. Small fragments from the rag would get left in the system. So Ford pretty much forced the dealers to buy the machine.

All I know is that Hyundai does not require a transmission fluid change on the 2011 V6, only inspection. Given that there is a 10 year - 100K warranty on the drivetrain, I would think they would be concerned if there was any danger in not changing the fluid.

Also, it is much more difficult to change the transmission fluid on a Genesis than older cars, and I would prefer not to have even a Hyundai dealer technician do it unless it was really necessary.

I'm not concerned with the first 100K I put on this car. I'm concerned with the second 100K. I know a lot of people change cars like underwear but I keep mine for a long time, much longer than any warranty so I change the fluids.

Here is my take on it, take this for what it is my opinion, I know exactly what Fast is talking about the machine is very handy and it can do "changes" or "Flushes" I worked in a chrysler dealership years ago, Oil change tech shit like that, The only difference in a flush or change is the flush you add a chemical to clean out the inside of the trans then refill with clean trans fluid.


Now as to my thoughts on why they had to drop that trans, it seems some places do not use those machines, maybe to make more money? $315 vs $80 if using the machine.
all automatic transmissions use between 12.8 and 14.2 quarts, cars not larger vehicles, from fully dry. but the pan and valve body only hold just over 1/2 of that so if you drain the pan, 4-5 quarts on average, and let the valve body drain for hours you may come up to 8 quarts. So they pull the transmission away from the engine and pull the torque converter and drain and refill that.

Or use the machine pull one trans cooler line connect 2 hoses one to the trans line one to the radiator where that trans line had been connected. start the engine, all fluid is pumped by the car through the machine put your chemicals in let it pump through the transmission then divert the old stuff to a storage tank that is part of the machine, while you dump fresh fluid into a tank that feeds into the transmission refilling it.

Sorry for such a long post, and for all the grammatical mistakes.
