Does the factory have electrical tape on the connector that you would normally put the resistor on the trans. The reason I ask is because I bought my truck used and it has always had kind of a hard part throttle shift. It's not as smooth as the other auto dodges I own. I read grimreapers thread about his resistor going bad so I thought maybe the previous owner installed a resistor. I haven't had a chance to really get into, I only shined a flashlight underneath and saw a small amount of electrical tape at the end of the plastic wire loom. If this is factory than I will safely assume that it was untouched, otherwise I will dig deeper to see if I do in fact have a resistor in place.
