Can I use Dexron 3 in my T-case?

[TWilkening]

I've been thinking of changing the fluid in my transfer case. I looked in my manual and it says to use Dexron 2 in it. I have a case of Dexron 3 laying around from a GM car I used to own, and now we don't have a vehicle here at home that uses it. So I was wondering if I could get by with using it.

Yup. Dextron II is just old school stuff. I don't know where you'd find that even.

NO---->The gear driven NP205 takes only gear oil or 50 weight motor oil. Chain driven NP transfer cases take ATF, but we don't have those kind!

Brian, he's got a gasser Dodge. It might have the NP208 in it, chain driven, uses ATF.

According to the Owner's manual, my t-case is an NP-241

The Dexron III would be 100% fine if Dexron II is suggested by your owner's manual.

According to the Owner's manual, my t-case is an NP-241

If the case is all Aluminum it's probably a 241. But go under the truck and just above the fill plug there will be a metal tag that will tell you if it's a 241
