Amsoil is for SPIII applications and has been highly recommended on this site in previous threads.
If you had a full flush done with Dexron III, see if any Lubeguard products convert the Dexron III ATF to SPIII.
According to another thread, Valvoline Mercon 5 Full Synthetic can be used in SP-III applications and Valvoline provides a warranty:
SP-III
I'd be cautious if the car has a manufacturers warranty though. If it's a Hyundai, the dealers swap out defective transmissions and ship the bad ones back to Hyundai for rebuild. They test the fluid and if it's not SP-III, you might have a warranty cliam denied. Then you'll have to argue with Valvoline about who is liable. That's more aggravation than I want to deal with.

You WILL NEED either a total flush with an HFM'd equivalent fluid, or an ATF fluid converter.
Some fluid convertors are Lubegard, Smartblend, Runrite, Mighty VS7.....

You probably need to be asking why this fluid did not make D-IIIH spec?. There must be a reason. The D-IIIH requirements are more demanding in several areas.
By the way there is really no such thing as a converter fluid or additive, the chemistries are way too diverse to be able to 'convert' one fluid into another by throwing in some concoction. It's basically just marketing hype. Buy the proper thing and use what the OEM recommends, whoever they are.

I think that the only thing the fluid converter adds could hope to accomplish would be to change the frictional properties enough to make it shift similar to the OEM fluid. But I would think that viscosity and other properties would be impossible to match with one of these additives. It might work ok in a pinch, but if under warranty, I wouldn't recommend it. Sort of a crapshoot...
