I've been reading all morning threads on here about regearing. But most have to do with the old 5.9 or the new aisan trans. I have a 14 3500 crew long 6.5 inch suspension lift. Run 37/13.5/22s since its had 18k on it. Trans broke input shaft at 105k on a sledding trip out west in feb 2020. Installed a jasper trans, lasted 4500 miles, 2nd jasper lasted 300 miles, now have about 500 on this one. The originally had 68rfe and 3.73 gears The truck shifts really fast and often so thinking of goin to 430 or 410 depending on if I have to change the carriers or not. Have a couple shops saying it could throw the truck into a limp mode like the jeeps do and may need to have the dealer reflash. Now I'm lost lol. Any input would be greatly appreciated!! Alot of knowledge on here, ty for letting me be apart of it!
