How to disable overdrive on my '03 Cadillac Deville?
I'll be towing a trailer about a thousand miles and back, and did so with a different vehicle before with the
warning that I should turn off overdrive. In this car, though, there is no overdrive switch that I can see.
Should I run it in 3rd gear, is there a button somewhere that I'm missing, or what? Any help is appreciated!
