Anyone else use this ATF in their Gladiator 8-speed?

Considering my driving profile, and @shadowpapa 's take, I think 60k sounds like a good spot for a change on mine, with likely a good safety margin. Glad I did it then.

One reason to not get 100% hung up on some numbers is some scientific testing I've read about where - aged fluid if not take to extremes, can actually help the friction disks grab, and be better at some things vs. new - and there was a huge difference in the two fluids used in this test (called only by 1 and 2, no brands)
There were hints that artificially oxidizing the fluids in a lab actually helped certain performance aspects.

You’ve come a long ways since April having never heard of this in all your years.

I guess it’s easier to just resolve the fact the transmission is mostly forgot about because it won’t drive down the road if the clutch plates have nothing to grab on to. Back in April, this was a crazy thing to say…

Ok, so you think I’m freaking out about numbers or I’m “spooked” by my first transmission (which by the way, no one here offered any clarity on what glycol contamination in ATF actually does to the clutch plates and that doing any sort of oil change, whether via pan drops or flush wouldn’t fix the problem) or that I’m writing some thesis, or why am I talking about Oxidation when no one else is… and, what’s the big deal about “full syn” and semi syn” anyway? Let me try as hard as I can to help you out. You’re not an easy nut to crack (not that I’m trying to do that)

1. I’m a critical thinker and can’t help it. We don’t have nearly enough of this type of thinker. We have more “yes men and woman” than we have those that will second guess what’s being sold.

2. I don’t freak out or react about numbers, I respond to taking necessary action when it’s suggested by (science) the lab and I mention what I do here. Others here make a choice to get grumpy, thunder stomp and shut down critical ideas.

3. I’m sadly not writing a thesis but I’m flattered that you think it’s this large and to think I never went to school for this.

4. I’m the only one talking about oxidation… I don’t know why. Sad no one else sees it. I’m alone, like you in some ways. I’ve never read anything but I’ve hung around those that know about it and I’ve spent time in the back of the lab talking with elite lab techs that try to dumb down what it is in two minute paraphrases. …and yes, it’s critically important.

5. What’s the big deal about “full syn” vs “semi syn”? The difference is in the synthetic spike the lab sees when testing for oxidation. Full synthetic has a massive spike that beats back the negative effects of oxidation for longer duration vs a much smaller synthetic spike in a semi synthetic that doesn’t protect against the negative effects of oxidation as well or for as long.

As the lab explained to me oxidation “can not” get past the spike unless the synthetic quality has withstood it for too long. A “taller, wider” spike provides more protection than a “smaller, narrower” spike.

I drive between 30k and 36k every year . So a once a year approach for me seems fitting especially since I am in Dust and dirt and steep hill and constant on and off the throttle type situations every single day.
@Maximus Gladius if it is changed at intervals to meet ones particular situation then Oxidation plays just a small role IMHO.
Most driver will fall into the 90k as all miles will be easy
60k for those with mixed activity
30-40k for those who meet the severe duty .
Disclaimer: I have no data to back that up its just an opinion .
Opinions are opinions thats it.

Once a year makes sense. It’s my interval too.

If anyone is interested in what oxidation is and what it does. This article is a great read. The links within are full of valuable information.

I checked my fluid level again last night, after about 150 miles on the change, and this time checked the temp at 110 degrees. It wound up taking about a half pint more fluid. That was a little more than I expected, so maybe there's more expansion over 30 degrees than I had imagined.

So it's an oil change and a couple of off-road lights away from being ready for Moab in a few weeks!

One sentence:
Nicely done.

But you wrote two sentences to say it was one?

Yeah, I thought of that.
Maybe use a comma instead, to make it one?

Thanks! I meant to say 1/2 pint...but that still shows more expansion than I had imagined.
