Normally it would make sense to just go ahead and rebuild the 80 but I already had the 90 laying around so I guess the real question is could I just have the 90 flashed with my vin?
Has anyone put a 6l90 instead of the 6l80 these trucks come with, was curious if it’s plug and play or? Also what can I do to beef up the 6l90 before putting it on, any info is appreciated
