You gonna soon be happier. Sounds nice but I don't know what the "Express" means.
Those shifter buttons are as you surmise. They are for downshifting. Used mine for the first time towing my toy hauler and going down some steep mountains in North Carolina. They work.
Never tried to upshift with them. Just ease off the throttle for upshifts. Might try that and see if it works. Not a fan of all the computer/buttons. I came off 54 years of manual transmissions. Just the whole idea of an automatic has not been a pleasant experience for me.
