Amsoil ATF in my Elantra?

[flinter]

Hi,

I had flushed trans and switched to Amsoil ATF on my 2006 Elantra
GLS at 29500 mile and now have 43000 miles of smooth shifting.

However, I am continued to be warned by the kids at Elantra XD
that my trans will fail now at any time!

They claim SPIII is "very specific" fluid, made just for Hyundai and that the Amsoil is slowing "eating away the plastic parts in the trans" and its just a matter of time
before it fails.

I tell them Hyundai does NOT make the ATF, it just relabeled
with "Hyundai SPII". They just refuse to believe it!

Why do these silly, immature lies continue on ALL the Hyundai
forms??

Because no one has been able to prove them wrong, apparently.

Eneos makes SP3 fluid as well.

The real question is why do dumb people buy Hyundai vehicles and anyone with some technical knowledge is trying to run a 1990s Civic forever. I realize Hyundai has only become a good manufacturer recently but the lack of technical knowledge on their forums is disgusting. Makes me embarrassed to be a Hyundai owner.

I was on that forum a few years ago and it was a total joke. They have NO idea what they are talking about.

I've had Amsoil ATF in my Dad's 03 Elantra for years now with no problems at all.

Tempest,

YES, Hyundai has these kids brainwashed and when you challenge
them to provide documented proof of situations where Hyundai
has denied warranty work because SPIII was NOT used, they
just viciously attack and use vulgar language towards you.

No a single one of them would ever provide any proof of their
claims!

Tempest, how many miles you have on dad's 03 Elantra?

Geez, and to think I was losing sleep because I put Castrol Import Vehicle ATF in mine! I own two of these cars; maybe I'll put Castrol in one, and Amsoil in the other!

One of the posts on their site going back several years mentioned all other fluids melting rubber parts in transmissions. Now, I really can't say I know anything about how transmissions are constructed, but can they really be made with either rubber and/or (as a previous post mentioned) plastic parts in them??

 

[flinter]

I also was wondering the same thing! Rubber and plastic transmission parts??

It has just over 100K now. Its had Amsoil for 3 or 4 years now?? I never made a log.

Rubber and plastic parts are probably the seals which IS a potential issue, but reality doesn't seem to back that concern.

The sensors are also plastic. There's tons of O rings and D rings in the transmission that are rubber. When you get your transmission rebuilt, all they are doing is replacing friction/clutch plates and the rubber/plastic parts.

What is more unbelievable than SP3 being some super special oil is the fact that people think Hyundai uses some special plastic and rubber in their transmissions that any other ATF is going to destroy. Seriously hate the Hyundai forum people.

My wife drives a 2007 Elantra. Somewheres around 30K miles I put in Amsoil ATF and it was kind of ok but the shifts were a bit too smooth and too much slippage if that makes any sense. I had a wheel bearing changed by my car mechanic brother in law and he mentioned that the transmission feels like it is about to fail. It wasn't, I think, but it just didn't feel right. Went to the Hyundai dealer and bought their fluid and exchanged out the Amsoil. Then the shifts were back to normal. The car is high 90K miles now and running great. Of the 3 cars I've tried Amsoil ATF, it only worked satisfactorily in one. 1999 Dodge Grand Caravan 4 speed, way too much slip, took it out within a few days. 2007 Hyundai Elantra, it was in for a few weeks, then flushed. 1999 Cadillac STS, no problem. For the Hyundai, I will try ATF+4 at the next flush.

Over the years Hyundai, Kia, and Mitsubishi have denied claims for transmission repairs if the factory fluid was not used. That's a fact, although it has never been made clear to me just how they sort out what fluid is in it.

On an elemental analysis the SP-III looks pretty much like Mercon V. I have seen as much variance between different analyses of SP-III as between Mercon V and SP-III.

The SP-III ATF is a highly friction modified fluid whose physical characteristics also seem to match Mercon V pretty closely.

In my own Hyundia, Kia, and Mitsubishi experience I have substituted the following for the SP-III in a full change with no ill effects:

Mobil 1 Synthetic ATF

Toyota T-IV

Redline C+ ATF

Redline D4 ATF

Motul Multi ATF

and have run them 30k or more miles. Of that bunch, my preference is for Redline D4 ATF primarily because it seems to shift better in extreme cold than all but the C+ ATF and I can use it in some other vehicles.

Amsoil ATF is one of the best, i wouldn't worry about it for a minute.
You could throw a bottle of Lubguard platinum in the mix for peace of mind and to keep the kids happy, its good stuff and may provide some real benefits in some applications.

Is it necessary? No but it 100% wont harm anything either.
