If you want the lock up converter to work you’ll need another switch to lock it and a circuit to unlock it and the o/d when the brakes are applied .
Without turning the lock up converter or the o/d off manually every time you come to a stop it will bog the engine down to almost killing it before the trans comes out of o/d on its own.
If the switches are left on the converter will lock up when shifting into second and the o/d will engage when in third and hits 45 mph .
BTW when engaging the lock up converter it feels like a shift . DON’T do this at anything over light throttle repeatedly or you get to replace the converter and hope none of the converter clutch lining contaminated the rest of the transmission. Ask me how I know .
If I put o/d in my dart it will be a Gear Vendors unit .
I put one in my Avalanche behind 4L60E and later I installed it in my Tahoe behind 4L60 with just buying the trans adapter .
If I decide to put it in my Dart it’s just a mater of the trans adapter . No floor mods needed.
