Tranny fluid and transfer case fluid question?
#11
There are several different things being talked about here and hard to keep up.
ATF+3 was discontinued in 05 and replaced with +4. If you have some old fluid still to use in an older than 05 vehicle, you'll be fine in both and auto tranny and tcase. The main difference between the +3 and +4 is the +4 went to using group 3 basestocks(synthetic??) as opposed to mineral based.
Dexron is GM's rating on fluids and really shouldn't matter for this discussion.
The NV4500 does need a GL-4, not GL-5 rated 75/90 gear lube.

For the most part. Synthetics control heat better.(usually) That and the last time I priced it, The Amsoil synthetic fluid was cheaper than the Mopar fluid by a good margin. IIRC The Mopar fluid is The Castrol Syntorque anyways.
