Only have to make the below changes. The 726-15-01 is the same as the 1st 2 digits of the tires circumference are the same. Just the last 2 digits. 35" (0A5D) and 37" 0AC1)

37" = 726-15-02 C1xx-xx
35" = 726-15-02 5Dxx-xx

Yes you will do a trans relearn. It’s all super easy. I did it with my 35-37 truck. Speedo is spot on now. I am on the factory 37 bfg’s, but I’d venture to guess it will be near spot on with any “37” tire you use. I didn’t do anything else, nor would I.
