Is OVERDRIVE needed with a programmer

[7.three]

My OD knob broke off the gearshift lever on my 01' 350 and I can't keep it glued on. (I know, a new gearshift lever only costs $50.00 to replace but due to the weak design I have no confidence a new one won't crackle and click and then finally break off again just like the original.)
I figured a way to permently re- attach the knob back on but the wires are broken too.
I plan on putting a PHP tune in in the future and am wondering with a couple of towing settings will I ever need the OD "off"again? I rarely ever tow and used it before anyway.

The wires being broken should just mean that you cannot turn OD off. You should be fine as the transmission will shift through all four gears as it is supposed to. Just be careful if you do tow something heavy. BUt most people (myself included) only turn off OD while in town or city stop and go type traffic. Doing that just keeps the tranny from constantly going in and out of OD

I have to shift out of OD. on hills, or my exh temps go way up.

I'm just wondering what happens to the OD "off" mode after adding a tune? If I install a Beans or PHP with a couple of tow settings, is the OD put in "off" setting as if towing as a stock truck without a tune or does OD "off" become an obsolete funtion and OD is left permanently on when in a tow setting once a tune is installed?
