The DD is just a helical gear drive so any extreme pressure / high shock / low friction oil will work. Me personally am not a fan of auto trans oil in anything except an auto trans. Auto trans fluid is more of a hydraulic fluid then a gear oil. But I can tell you I know guys who swear by it in all kinds of gear boxes. I reread this and your talking manual trans/diff fluid right? I would say you should be ok, just use the correct amount for your application.

Ive used Amsoil 80/90w full synthetic gear oil for the past 6 years on my 07 m1000 so Thats what I would recommend

Amsoil sells oil made for the DD. I've even read they are the ones the supply BDX the oil and BDX relabels it.
I pondered using something more convenient/readily available, then I ordered Amsoil online. 2 bottles. Glad I did. I trust the oil, but also, the bottles are really cool with the spouts that come with them. I will use the bottles for other things like adding oil to stuff that you would typically have to use a funnel for.

I have been guided to run this Redline oil in my DD, from a pretty good Cat mechanic that I trust

Go to the Amsoil site and, ah it's easier for me to do it...

The oil I got a month ago included little spouts/hoses, even though website didn't show them. Nice.

Thanks
They sell a "chaincase" fluid and I've been using the 75w90 gear oil, too.

I used plain Jane 80/90 gear oil. 2000 km ago no problem. This reminds me that I need to change it.
I spilt lots out of the 5 litre jug trying to fill the dd with a large funnel but it didn't matter because it was cheap oil lol.

isn't ac oil thinner then 75/90w I would guess it to be more like 32or46w

Royal Purple Synchro full synthetic... never an issue with any of our Diamond Drives, , we drain, flush and fill it annually.
I've used this stuff in an aftermarket manual transmission. If you're ever trying to clean this stuff out, it's near impossible as it coats/sticks to EVERYTHING.
It's also bright pink, so you'll know it's leaking if you ever see it!

The cat dd oil is very lightweight like 10w hyd oil.
The old myth that you could only use cat oil is untrue as almost any oil will work ok.
I still use a lightweight oil especially on my 05 cause only 3oz of heavy gear oil could get all slung onto the case and have no oil bath for the bottom gear to run thru. But looks like plenty of folks using 80-90wt with no issues.
