I haven’t seen or heard of this particular one, but MasterShift (I believe) had one that would strip a gearbox so clean you had to pick up the pieces with a mop and a magnet. Biggest trouble was people expected clutchless shifts both up and down and the shifter did not manage the clutch. These guys indicate that it will do clutchless upshifts - but you have to wonder how much wear it’s introducing to the sliders and dogs of a normally synchronized transmission...
