I'm getting ready for my 30K maint. and was wondering what tranny and axle fluids people use? Is ATF+4 only available from the dealer?

ATF +4 is available in many varieties. I use AMASOIL ATF4 and Severegear Amsoil in the diff

I'm using Amsoil Severe gear oil as well in the diffs.

Spec for the axles is full synthetic 75-90 that meets GL-5 standard. My dealer says 75-140 is preferred for people who tow heavy in a climate that gets hot.

I run Redline, 75-90 front and 75-140 rear, and Mopar ATF+4 in the transfer case.

I run Redline heavy shockproof in the front 75-140 rear mt-90 in trans and I forget what in transfer case.

Mopar ATF +4 from the dealer in the trans, transfer case, and power steering pump every 20k. (Don't forget to buy a new trans filter)

Mobil 1 75w90 in the front and rear Diffs also every 20k.

While im at it, I drain and refill (not flush) my radiator with new Zerez G-05 coolant mixed 50/50 with distilled water.

Change oil every 5k, stock fuel filter every 10k and added 2 micron spin on fuel filter every 20k.

Probably overkill, but works good for me so far.

Royal Purple Synchromax in my Trans and Tcase...but I'm out of warranty. Worked better for me than slushbox fluid. Pennzoil 75W90 in my diffs...the price was right, it was free.
