the mark8 TC will help in around town ONLY. when on the highway, it will be stalled or locked, just like the stock TC.
go out to your car, put the trans in 2nd, and mat the gas. notice that the tach shoots up to about 2 grand, then slows, and that is when the car accelerates? that is the TC stalling. the mark 8 unit won't stall until 2400 or 2500.
