You have probably been using the older Mobil 1 ATF that's rated Mercon only, not Mercon/Mercon V which is what they've changed it to.
I think the problem with Mercon V or Multi-rated ATF is the clutches in the auto trannies. AFAIK, there shouldn't be anything like that in the transfer case (or 6-speed) that should be affected, but I'm not sure.
It would be interesting to see what a newer owner's manual says about Mercon/Mercon V or Mercon V in the t-case and manual trannies.

[/ QUOTE ]I am not sure about that either, maybe I will just play it safe and run the chevron non syn.
I have been running the older mobil 1 syn. too with no problems. But the new mobil with mercon 5?? /ubbthreads/images/graemlins/shrug.gif

Kevin, you are correct, the problem with the dual rated fluid is with the clutch packs in the autos. The syncronizers(brass) are not affected in any way by a dual-use fluid, and it still provides the same lubrication to the bearings and gears. The dual-use can also be used the transfer cases and power steering systems without harm. I have been running the Amsoil universal ATF in both trans & transfer case in my 99 for over 2 years/35k miles with no problems.
I posted in another topic here three days ago, and there was a similar confusion about the dual-usage fluids in the manuals and other systems.

buddy, so your saying it is ok to use Mobil 1 (mercon/mercon V) in transfer case, power steering, tranny? You said the problem is with the clutch packs, If this is a problem, then why are you running it in your trans?

Sorry about the confusion, my 99 truck is a manual transmission, so it is OK to use the Mercon/Mercon V fluid. For my 2001, which has the automatic, I ordered Amsoil's Torque-Drive, which only carries the Mercon rating.

[/ QUOTE ]So I think I will order some amsoil torque drive for my power steering and transfer case. Do you know where I could purchase it from? It sucks that I can no longer purchase synthetic ATF from the local autozone, kragen, etc.. I guess everything will have to be done online.

Give Bob Riley a call at Dieselsite. He is a Amsoil dealer and also a site sponsor. He is also a great guy to deal with.

I just looked at the amsoil site and wow! /ubbthreads/images/graemlins/shocked.gifEach quart comes out to $10 dollars including tax and shipping. What a deal. I think I will order a hundred! And I thought gas was high /ubbthreads/images/graemlins/shrug.gif
I've been running Mobil-1 ATF (Mercon/Dexron-III rated) in my 6-speeder and
transfer case since I had 15K on the clock. Now have 45K on the clock.
A few months ago I started reading about the dual-rated Mobil-1 ATF and so
I started looking around the stores here to see what was on the shelves.
At that time only the old Mercon/Dexron-III rated Mobil-1 ATF -- so I
bought several more quarts of the stuff. Then about a month ago my
local/yocal Bi-Mart discount store got some of the dual-rated Mobil-1 ATF
on its shelf. I carefully looked behind the front bottles and found five
more quarts of the old stuff, so I bought them... Went to another
Bi-Mart store and all they had was the new dual-rated stuff... Then I
stopped at Autozone and by gollie they had 11-quarts of the old stuff.
Bought all 11-quarts! Now have 34-quarts on the shelf in the shop...
That should last me awhile... Especially since I just put a tranny
ATF filter on the 6-speeder...
Anyway, if you look around at your local stores you may still find some of
the old Mobil-1 synthetic Mercon/Dexron-III rated ATF around... Check
carefully at the back of the shelves!

FYI, Royal Purple has a MERCON synthetic ATF. It is called "Royal Purple Max ATF". It is not the MerconV we need to avoid in our automatic transmissions. I just did my trans this weekend with it. I used some dyno. MERCON ATF to flush out the power steering pump.
