It has a cooler, and the fluid is clean and doesnt smell burned. Most of the time it goes away once its warmed up.
Any Ideas?
Thanks

Being an automatic, I would think it almost has to be internal to the tranny. Particularly since it goes away once warmed up.
If he's got 130K on his tranny, he should consider himself blessed. The durango has the same tranny as the jeep jerokee & the dodge dakota. They are not highly rated. Got mine redone at 85K. It never slipped once but was bleeding from both ends & making a roaring noise as soon as the overdrive engaged.
Can try getting a pressurized flush but some people recommend against that with older xmissions. Seem to think it can blow out old components. I do know people that continue to get it done on older cars/trucks well past 200K without incident. If it looks like it may go anyway, you are taking a $50 to $75 chance at fixing the problem or at least delaying the inevitable. I wouldn't bet heavy on this solution. My tranny experience ends at changing the fluid & filter.
Good luck.
