The local dealer sold me mopar nv3500 and I put it in my 6er when I changed it. Since then I hear whorer stories about the wrong lube in these thingsand what it does to them. So... is this the right stuff?? Thanks

 

That is the right fluid for your trans, the spec# is what really matters.
When I changed mine for the 1st. time they gave me that fluid and I didn't have the spec# so I asked if it was right for mine, they told me no and sold me the NV4500 fluid @ $18.00/qt.

 

Read your owners manual, it will have the spec number listed for the NV 5600. Pennzoil synchromesh has the correct spec number and can be bought at most Auto part stores for half the price of dealer.

 

Here's a link to an article I have written on another diesel truck site that may help you a bit :
