Shift Firmness

Recommended Posts

Mine did the same thing for the first 60K miles or so. It is some sort of pause in the shift done by the computer. I believe that GM makes it this was to make for a more luxury type ride. In my mind it is just good for causing unessary heat in the tranny. A good westers tune will take care of it. My Tahoe shift much better now but it is not hard shifting at all.
