It's likely t be an internal transmission problem but I would start by getting the oil hot, drain it drop the trans pan change the oil and filter using the correct Dodge fluid and add a product called Lubegaurd its quite a good additive. When the oil pan is off check for debris in the bottom of the oil pan.
