I am going to have to save for a bit before I do any thing plus I still have to get the ting running first and it there is no doubt it will be driven for a bit I am ready to pull my hair out with vicegrips with that one all I can say is I now know why when people go from diesel to gas they go carb or aftermarket efi and if they have a electronic automatic they get a stand alone deal or switch to a no electronic trans some might even swap in a manualBefore you start spending any money give this a try.
Put your shifter in 3rd gear and drive around for a few days or a whole tank of gas.
If it pulls hills great and your happy with how it holds speed.
Then you got a idea on how it would normally act in overdrive with 5.13s within a few rpms of the 4.10s in 3rd.
