Manual shift mode cannot be permanently disabled. In the situation you outlined, why didn't you just hit the paddle shifter to upshift to the next gear?I am occasionally hitting the gear shift paddles behind the steering wheel accidentally. when I do, the Envision changes from automatic to manual transmission. This is inconvenient, and today almost caused me trouble in heavy traffic. I was in gear 2 trying to go 40 mph. The loud whine the engine made was my clue. This is a 2021 Envision.
Can these paddles be permanently disabled? The paddles on my wife's Enclave do different things and do not cause a problem for me.
