I've still driving my stock TH350 in my 81' Malibu until I got the time to put my built 200R4 in, but around town I find the lock up converter is annoying in traffic. Has anyone added an auxiliary toggle switch along with the factory vacuum switch? Will this hurt anything? What i'm looking to do is run the stock switch but be able to activate the lock up when on the highway and not when I'm doing 50 in traffic lol.
