MPG and the OVERDRIVE button?!
Hey everybody. Been gone for awhile. Anyhoo . . .
Can anybody shed any light on a longtime household argument: "Is there any signifigant difference in gas mileage when driving in town (40 mph and under) with the overdrive on (light off) or overdrive off (light on)??!!

If you never go into OD in town on a normal basis (letting the tranny shift itself into OD) then there would be no difference. If it normally does go into OD and you override the OD, then you will see increased fuel consumption simply because you are turning more RPM than if it were in OD.
Turning off OD does not give the tranny a different shift program or anything like that. All it does it prevent it from shifting into OD.
