Hello,
I was under the car today looking for the tranny drain plug. Is it the plug that is on the driver's side under what looks like protectin fron a plastic gaurd plate? Also, the book states that it tales over 11 qts for a fluid change. Is 11 qts really true? That seems like a lot to me.

Hi Highlander 1

If you are doing it yourself and are just draining the atf from the atf pan then you need to measure how much came out of the transmission and add just as much back in. It is not possible to get all the atf out by yourself since some is left behind in the torque converter and other crevises. But if you are going to do it, then I would suggest you buy at least 10 quarts of atf and go from there. Buy some synthetic. The Azera atf is semi-synthetic so it should be almost the same.

What Peter Gunn said, but with one exception buy ONLY Genuine Hyunday ATF SPIII anything else will do damage. If you do a search you will see about this peculiarity of Hyundai trannies. Hyundai is semi-synthetic,but we don't know what else there is in it, only that if you don't use it, big troubles.

Thanks for the reply,
I looked into it and Amsoil ATF is able to be used. Amsoil is a full synthic and has much better properties.

if you want your cars tranny to die a quick death by all means save a few $$ on aftermarket fluid. its your car afterall... :amen:

Amsoil ATF is 3 times the price of anything the dealer would sell. Do your reserch on quality oils before making such comments esp in regards to price. Amsoil and Redline set the standard!

Scott

ok so i was wrong there, but you will mess up your transmission using anything but hyundai atf.
just cause it costs more, doesnt means its better for your hyundai.

I would normaly agree in regards to the tranny fluid. But, I have had very good luck with this stuff in other cars, one is raced locally. I think if you have the chance to use this it works wonders. But, I will try to do more follow up on it. The product site does say it exceeds what our requirements are and Hyndai SP !!! is directly mentioned.

The Amsoil atf should work for the Hyundai transmission. However, the transmission fluid thats comes in the Hyundais is already pretty good. Performance or shifting will not improve all that much with the Amsoil because the transmission is already well calibrated for the job it was designed to do.

Best of luck

what kind of improved transmission performance are you speaking of with the Amsoil product ?

I would never run anything other than Hyundai ATF, the aftermarket can claim their ATF is good for all makes/models, but last I knew the only company that made ATF compatible for a Hyundai was Pennszoil. 11 quarts is likely the entire trans capicity, I doubt you'll drain more than 5 or 6 quarts by using the drain plug.

Just take it somwhere and pay the $100 to have it powerflushed. Its the only way to get all the old fluid out. You wont want to mix hyundai fluid and amsoil.

automatic transmissions have a generally longer break-in time then engines so I would be very careful with the transmission if it has less than 20,000 miles on it. I would also recommend a power flush to get all of the old transmission fluid out and get the same amount of new transmission fluid back in.

A couple of thoughts on the tranny fluid change:

As far as I know the Azera tranny does NOT have a pan, rather just a drain plug. I believe there is a small screen rather than atrue filter as well.

I'm mixed on a tranny flush vs a drain & partial change. While I ike the idea of a 90 -100% fluid change with a flush for obvious reasons, having setiments, dirt and particles that were harmlessly lying in the tranny dislodged during the flush process and not finding their way out may lead to problems that would not occur if a simple drain of fluid was done. Down side to drain & fill is that you'll probably only change 40- 60% of the fluid.

Amsoil products are teriffic for sure. Personally, I'll use the Hyudai fluid - not becaus I believe it's better than Amsoil or Redline, but if I need to make a warranty claim on the tranny, it's easir to say the fluid was changed on time with your own fluid... just my 2 cents.
