My truck transmission is an NV5600. The truck is 4x4, limited slip. I have noticed fluid sprayed on the underside of the bed where the drive shaft is connected to the transmission. I am still under warranty for 3 more months. Someone told me this is a typical problem and not to worry about it. I don't have much confidence in the Dodge service in my area. Is this something I should get fixed before my warranty runs out?
