Just like dexos engine oil, anyone can certify as dexos, but has to pay a licensing fee to GM, Dexron is the same. And they won’t sell that certification anymore, GM should recognize the classics market and market a Dexron 3 themselves. People would buy it haha

Different brand but same idea as what I used. Thx

yes, that was my point. Anything will be an equivalent. Which is what I used. If she blows up she blows up, there’s clean old formula ATF in it, haha. thanks for the replies guys, I’m finding this to be a great active forum,

i guess my concern is that, GM no longer licenses Dexron 3, so everything is technically an equivalent. I guess at that point I just need to trust the brand I choose,

I was thinking of switching to that Delco manual Trans/tcase one, should I ? Or as mine is aluminum just leave my dex3 equivalent ?

Yes from 80w90 in the diff to Dex vi in the trans it’s a wide difference.

No worries , it’s good advice. The the guy I got it from just drove it. But he only had it on the road for about 100 miles til I bought it. I disassembled all the carpets and such and shop vac all the junk out. Spray lubed a lot of stuff. It’s not an exotic truck but it’s mine.

Ok thanks. I guess if it’s no good I’ll find out eventually haha. It’s solid advice though, change everything, that was my outlook. Even the last owner, I know he did nothing and even if he did, I wanted my own baseline of dates, mileages, what I used etc, Same with spindle bearing hardware...

Trans and filter is being done this weekend. That fluid is correct level and very clean. I’ve been a diesel tech for 20 years, so all I’ve been doing is catching up on the maintenance before I start using the truck. To be honest, every fluid except the coolant was clean and looked/smelled...

yes, I’m in process of doing this. I didn’t trust anything. Have to do trans filter and fluid and wheel ends when my spindle locking hardware arrives. But the question remains, is the Dex2/3 equivkianr fluid ok?

I only recently got my hmmwv, and while doing fluids and such across the board I found my transfer case quite low on fluid. I used what we had on hand at work. It’s called MD3. It’s an ATF meant for older vehicles calling for Dex 2/3 and the older Merc. Should this be ok or should I source...
