Do You guys even know why You recommend Hyundai ATF SP3 ?

I dont know what company makes it or what is the fluids specification, properties, what makes it so special.
I want to buy ATF like I buy motor oil from the gas station. Nice and simple.

So as the result of having all that history of transmission issues with Hyundai ATF right from factory, I just dont know What to think.
Owners manual says: "Hyundai ATF SP-II, AUTRAN MMSP-II or DIAMOND ATF SP-II.

As I tried to find equivalent to these ATFs there wasnt just enough info.
So I bought the best ATF from gas station available. It happened to be Valvoline Type D - Dextron IID equivalent with good lubricating properties.

So I added it almost to the full after driving the car hot.
I didnt want to put to full because I dont want it to foam.
BTW does somebody know what exactly foams it in the tranny?

sp 111 fluid is only available from your dealer, diamond fluid is available from a mitsubishi dealer......this is the only fluid you should be using, foaming is caused by air in the system

Yes air, like in engine , but it is oil reaching engines crankshaft, but in tranny there is no crankshaft - what thing exatly foams it and why - im interested.

If it would have been full tranny flush , refill I would be more concerned. BTW I have no warrenty to think about.

Thanks for the Mitsubishi hint Montego.

Foaming is caused - as you already remarked - by too much ATF. The gears in the transmission churns it up into foam.
When there are airbubbles in the fluid, it can also be caused by a low ATF level. Then the oilpump will draw in air along with the fluid.

Both cases can cause overheating or oxidation of the fluid.

And as montego said: Only MM SP-II or MM SP-III fluid should be used indeed. Dexron has other friction properties than the genuine fluid.
But you can not only get the fluid from your dealer. In germany for example, a "Ravenol MM SP-III"-fluid is available, which meets the same specifications as the Hyundai ATF. There is only one difference between both fluids: The ravenol costs much less than the genuine fluid. I think in other countries exists also some alternatives.

Furthermore, there is an additive called "Lubegard" (it's an american brand). It promises that it can "upgrade" Dexron to MM SP-III fluid. I don't know if it works...

Danny, how do You know Ravenol MM SP-III fluid meets the same specification of Hyundai ATF?

Do You have Hyundai ATF specification?

Its a good idea to add something if You know how much to add - that the new mix would meet the specification, but as I remarked I dont know.

"Foaming is caused - as you already remarked - by too much ATF. The gears in the transmission churns it up into foam. "
By gears You mean torqueconverter Danny?

Well, it is claimed by Ravenol. They say, the "Ravenol MM SP-III" is especially produced for Hyundai, Mitsubishi and Kia transmissions. They also claim, that it meet Hyundai ATF specifications.

Unfortunately I have no possibility to verify this statement because Hyundai don't abandon any informations. I can only tell you the specifications of the Ravenol fluid:

Technical properties:
Color red
Density at 20C g/ml 0,847
Viscosity at -40C mPas(cP) <17900
at 40C mm/s 31,8
at 100C mm 2/s 7,1
flashing point COC C >135
Pourpoint C -48

Do you mean Lubegard? They have a recommendation how much to add per liter ATF.

I mean normal gears in the transmission, not especially the torqueconverter. It's just what Hyundai says. But it's possible, that the "paddle-wheels" of the torqueconverter also cause foaming.

If this is true these should also be the specs of Hyundai SPIII.
---
Obviously Valvoline Type D is not the same fluid, its specs are:
Viscosity, mm2/s @ 100 C 8.0
Viscosity, mm2/s @ 40 C 41
Viscosity Index 161
Viscosity, mPa.s -40 C <50.000
Sulphated Ash, wt. % 0.30
TBN; mg KOH/g (ASTM D-2896) 3.0
Pour Point, C -42
Colour red
Specific Gravity @ 15/15C 0.875
Flash Point, COC, C 220

Can somebody show out some example specs of the fluid that ruind his/hers Hyundais tranny?

Yes I mean Lubeguard. The lubequard should be next to ATFs at the qas station.

What do You mean by normal gears Danny?

Well...a few thousand kilometers ago I filled Dexron III in my tranny, because the genuine ATF is really horrible expensive (20 per liter at my local Hyundai dealer). Before I used Dexron III, the shift quality of my tranny was satisfactory. But after driving with Dexron III the shifting fell off in quality. In addition, the clutches began to slip during the shifting operation (gear 2->3 and 4->5). So i did a tranny flush and used the Ravenol MM SP-III fluid, and the problems didn't worsen, but they still occurs. Now I'm afraid I'll have to overhaul my tranny

I can't say if all these problems are caused by Dexron or not. I don't want to spread a lurid tale, but the problems with my tranny just began at the same time I used Dexron.

Danny from internet I can see, that there are many Dexron III ATFs with different spec. numbers. Do You remember exact company and atf type/name to compare spec. numbers?
---
From my experience I can tell that the grindings and shutterings and bangings can occure even with the correct fluid and changed filter. Once I tought that when I change atf and filter gearchanges will go smooth. They didnt. In my case there still was old dirt glogging the valvebodys passages, and bad (finaly failed and caused banging gearchange) solenoid valve. So this solenoid was the 4th and the last solenoid valve of 5 that I have had to replace one after another in few years now.

Yes, of course, I used the FUCHS TITAN ATF 4000. But I can't find the specifications quickly.

Well, what about your tranny now? Does it work smooth?
I already changed all 6 solenoids, but there was just a small improvement. Primarily the slipping of the clutches while shifting from 2nd to 3rd gear disappeared. But the clutches still slip during shifting from 4th to 5th gear. Let alone harsh gearchange and harsh reverse gear engagement. And problems with the converter lockup clutch.

But surprisingly my valvebody was absolutely clean, there was no clogging or dirt in it.

But usually the F5A51-2 transmission (it's from mitsubishi) is said to be strong.

***EDIT***
Okay I just found the technical properties of the TITAN ATF 4000 Dexron III:

Specific gravity at 15C: 0,862 g/ml
Color: red
Flash point COC: 190C
Pourpoint: -50C
Foaming characteristics Seq.II: 30/0 ml
Viscosity at 40C: 37,8 mm/s
Viscosity at 100C: 7,6 mm/s
Viscosity index: 174
