Does anyone use this brand of oil? I got the synthetic ATF and 75W90.

ATF claims to be universal. 75W90 already has friction modifiers.

I tried searching forum and google.

Thanks,

What do you plan on using them in?

If you're planning on using the ATF in a Torqueshift, DON'T. You need Mercon SP or LV. I've also heard that Valvoline MaxLife is SP rated, but I wouldn't even bet on that.

If you're planning on using the 75W90 in the rear differential, and you have a F-250, or an F-350 SRW, DON'T. Those are a Sterling/Visteon 10.5 differential that requires 75W-140 synthetic.

 

Im using it in my 99 f250 SD SC V10 4X4
4R100, Transfer case,4.30 front, 4.30 LS Rear
The 75W90 already has friction modifiers in it for the rear axle.

 

The ATF will work find in a 4R100, since the 4r100 will work with about any Mercon V compatible oil. As will the gear oil be fine in the front differential.

You are taking a risk with your rear differential by using far too light of an oil. It calls for 75W-140 synthetic. But, it's your truck, you get to fix it if it breaks.

 

75W140? I'm sure the book I got (Haynes) said they were both 75W90.
I haven't changed it yet so no foul.
