Amsoil transmission fluid/differentials

[Jeremy Harris]

Hey guys, I got a 2019 Ram 2500 6.7L diesel. I was thinking about running amsoil signature series atf transmission fluid along with amsoil severe gear 75w-90 in my differentials. What are your opinions on this?

@daveray9 you saying go for it? The mechanic I spoke to seemed hesitant about it.

Transmission isn't due for a fluid change until 60,000 miles, why waste the money.... And is Amsoil really that much better? They have a great marketing campaign I'll give them that. I use conventional fluids.

I’m at the 55k mile mark already. Yeah, everything I’ve read or experienced in my older truck seems to point to amsoil being superior.

Amsoil gear fluid is top notch. The engine oil is the best too. If it's time for service I would go with Amsoil. That's what I plan to do once it's time to change out the fluids.

My MPG's and the cold starts all got better on my 2003 Expedition when I changed to Amsoil. Likewise, my rear differential was like new after changing to Amsoil. My rear was changed by the dealership and started making some shudder when turning corners. I changed it to Valvoline myself after a year and the shudder continued. Living with it for another year I said screw this time for Amsoil. Once I put that in the shudder went away totally after a few weeks of driving. My mpg's went up by 2mpg with the oil. This is a sample size of one but I was impressed.

Amsoil SG and Transmission Fluid are top shelf. UOA's on amsoil transmission fluid show next to zero shear, it is very good stuff. What transmission do you have?

I have a 2006 dodge 1500. I serviced the transmission with a full on flush, and filters. I used wix filters and amsoil OEM 100% synthetic. My truck wasn't shifting bad before, smooth good shifts. But I have always had good luck with amsoil. Could you use valvoline max life- full synthetic fluid? Sure, it would work great. But amsoil is probably one of the best oils . But I wouldn't hesitate to use valvoline max life- full synthetic at all.
