I'd have a look online in your home area (it says non-UK so no idea where in the world you are) and find a Dexron VI compatible fluid and use that, especially if you plan on periodic part-changes or full changes to maintain it. A quick search revealed that Pentosil #1 is a "life-time fluid" so is likely to be more expensive and won't necessarily last the life of your box. I'd prefer to do a part-change once a year or so to maintain the fluid than use a "lifetime fluid" that maybe breaks down and kills my gearbox. Each to their own though.......
