I have a JTRD on 40x15.50r20 w/ the EVO 4.5 lift. My take off is fine, but my truck shifts down in speed when I hit any type of incline. I’ve read a lot about the 3.6 and regearing for 40’s, but I can’t find information on the 3.0 in terms of regearing. Will 4.88 completely kill my MPGs? It’s already down to 19 mpg. Also I’m hoping this would make it easier on my transmission. Any help is appreciated
