If that's the case I might just wait and see how the 3.91 gears work with the converter I have and go from there. If I do get a new converter i'll probably talk to a tech over the phone and see what he'd recommend as maybe a compromise between the two. I love driving my duster on the highway and would just want something that slips a little less when cruising. Eventually I will be converting to manual trans so I don't want to put too much money into my slushbox lol
