So which Valvoline product is the best fit here, IMV or Maxlife? I didn't really know there were two choices, I thought it was just Maxlife and then Castrol IMV as another option. It seems that Valvoline IMV is a closer fit to the Hyundai SPiii fluid.
Also found this interesting post by Hokiefyd about the 2 fluids:

I wanted to update this post because I used some of this fluid tonight. Last time I changed the ATF on the CR-V, I found the aluminum washer to be leaking and all I had on hand at the time was an 18mm fiber washer. I used it and it seemed to work. When I serviced our Acura's ATF recently, I used one of these fiber washers on its drain plug and it leaked like a sieve. The fiber washer actually split in two. And I didn't torque it down much at all. So I became paranoid about this washer on the CR-V and bought an aluminum washer today for it...so I wouldn't drain the transmission if the fiber washer decided to give up going down the road. I also thought I'd try a few quarts of the Valvoline IMV ATF. I bought two quarts of it and completed the fill with some of the gallon of Valvoline MaxLife ATF I have on hand.
I will say that the shifting from the transmission is immediately smoother with just two quarts of the IMV fluid. Where the MaxLife produces a very firm shift, the IMV fluid almost mimics the OEM DW-1 fluid in its smoothness. I only have two quarts in it now, but there was a marked increase in shift smoothness. I personally thought the DW-1 was too soft/loose (especially in the Acura), and while I don't mind the shifts on MaxLife, I wouldn't want them any firmer either.
It's apparent to me that Valvoline's IMV product is a more friction-modified fluid than the MaxLife ATF. The MaxLife adheres to Dex III and other fluids that aren't as friction-modified as some of the Asian transmissions (or at least Honda units). While this seems to produce no harm to the Asian transmissions, and indeed may extend their life through better clutch wear, shifting is markedly firmer, at least in my experience.
If you are looking for an OEM-like shift quality, but want easier-to-find fluid, the Valvoline IMV may be a good choice. It's not exactly cheap, at $6.49/qt at Advance Auto (I think AutoZone may have it for $6.29/qt). But it is easier to acquire if you don't have a Honda dealer nearby. And I think it's superior fluid anyway, and will likely hold its properties longer than DW-1 does.
I think my perfect blend might be one quart of this to two quarts of MaxLife on each drain/fill.

Maxlife:
MAXLIFE™ DEX/MERC ATF
Valvoline MaxLife™ DEX/MERC ATF (Automatic Transmission Fluid) is the first fluid of its kind that is specifically formulated for the broadest range of today’s technologically sophisticated automatic transmissions. It is formulated with synthetic base stocks, unique seal conditioners, long-life friction modifiers, special anti-wear additives, and shear stable viscosity modifiers, among other components to fight the four major causes of transmission breakdown: leaks, slippage, shudder and gear wear.
Valvoline has conducted extensive in-house testing, independent lab testing, and field-testing to support MaxLife ATF performance in the broadest range of transmissions; however, it should be noted that MaxLife ATF is not a OEM licensed product. The respective vehicle manufacturers have neither evaluated nor endorsed MaxLife ATF in these applications. If an OEM licensed product is preferred we recommend Valvoline DEXRON® VI, Valvoline ATF+4® and Valvoline MERCON®V for the corresponding applications.
The Valvoline MaxLife™ ATF Advantages:
• Synthetic fluid
• Conditions transmission seals to prevent leaks
• Reduces varnish formation and wear
• Our best anti-shudder performance
• Improves and maintains smooth shifting longer than conventional automatic transmission fluids
• Superior anti-shudder performance
• Provides excellent flow properties at low temperatures and greater film protection at high temperatures
• Maximizes the life of higher mileage transmissions

The above constitutes only a partial list of applications approved by Valvoline. Please contact us at 1-800-Team-VAL for additional applications.
Valvoline does not recommend MaxLife ATF for use in most continuously variable transmissions (CVTs) and in dual clutch transmissions (DCTs) unless specifically noted, nor in automatic transmissions where Ford Type F fluids are recommended.
Valvoline stands behind all of its products, including MaxLife ATF. Use of MaxLife ATF in transmissions where recommended by Valvoline WILL NOT void the vehicle’s warranty. In the unlikely event that you or your customer experiences any transmission damage while using MaxLife ATF in a Valvoline recommended application, please contact Valvoline at 1-800-Team-VAL for assistance.
