Mr P Body,

Thank you for the concise information. You bring a lot to Moparts!

So if I have this right, I can put an overdrive switch in the car, and when it is turned off it will act like a normal 727- no worries on strength.

When the switch is turned on, Overdrive will be active and I would be good to go on the street.

Do you have to manually toggle the overdrive each time, or will leaving the switch turned on allow it to work like the overdrive in my daily driver?

Sorry for all the questions just want to be informed.
