Welcome back for another installment of “Ask Jack”, the place for you, the man on the street, to ask me, the man on the Internet, any question you like on any topic that makes its way into your mind.

Good morning,

I am planning a transmission swap in my 2006 five hundred from a 2WD CVT to the offered 6speed of the same vintage.

How about the PCM that controls the trans. They offer a few different ones, specifically: (Read More…)
