Thank you,I have my Chevy Owner’s manual,it does indicates (and I knew this by experience) I don’t have to monkey around with the Overdrive button unless I need to tow my boat and drive in steep mountain roads. I asked the question to support a friendly argument with a good friend-the previous owner of the Dodge-.I think the confusion arises from a communication problem, my friend’s driving habits involves locking out the Overdrive Off (indicator light On)when he drives in the city and then he said “he turn the Overdrive ON” when he hit the freeways,which in reality means he actually is Unlocking the Overdrive (indicator light is OFF).
I agree with you,just start and drive the darn thing,leave the darn OD button alone.
