Hey guys, Im having issues with this thing. Ive got a 2015 2500 with a 48re swap. Mods below... Im having issues with the transmission up and downshifting like crazy. at 35 on a small hill it will change gears like 10 times, same thing around 65 or 70. It drives good without a load but with the smallest load on it, it freaks out. Ive already had the controller replaced. Im running a tune that Lavon sent. Ive tried the tv adjusted at 80 90 and 100%. Any suggestions???
