How many of us are there? Owners of Dodge based RV's?

Thanks for the manual information and your posts!

"Dexron III fluid is the minimum one should use. For smoother shifting and less wear in winter, use Chrysler ATF+3 or ATF+4 (there are numerous “universal” fluids, and one which conforms to Dexron III and/or ATF+3/+4 should work). "

yes, it's the 2nd dana axle i use full syntetic 75w140 fluid, because it has very good lubricating properties and the highest heat reserves.
