Will the 5.9 engine fit bolt on to a Dodge Dakota tranny?
No, a 5.9L engine (typically referring to the Magnum V8) will not bolt directly to a Dodge Dakota transmission. The bellhousing bolt pattern and the transmission itself are different depending on the year and specific engine/transmission combinations used in Dakota trucks. You'll need an adapter plate or a custom solution, which is a significant undertaking. It's not a simple bolt-on swap.
