I am mapping out my next project so I wont be guessing like I did with the current one. I will be going with the 6l60e six speed transmission in my next g body. I know tci has transmission controllers but they are for the 4l series and their own 6x transmission. Just wondering if anybody knows a reputable company that sells the controllers for the 6l transmissions. Motor will be either a Twin Turbo Buick 455, Cadillac 500, sbc 350 or 305. If I get a car with a decent motor I will keep the 350 or 305, drop the usual performance mods and drop some really low gears in the 4.xx range. Should be a nice go getter with the lower gearing and six speed. I will probably keep it in the 4.xx range regardless because of the trans I am using though.....hmmm
