Okay, I have two problems with my G and am taking it in, but I was wondering if anybody else had these issues as well.

1. In traffic going uphill my whole car shudders and shakes. I am assuming I'm not giving it enough gas going up a hill (~1500rpm), but it shakes pretty violently. The clutch isn't slipping, it's the entire car shaking. I would say this happens maybe 30-40% of the time.

2. When I'm in any gear and I rev above 3000 rpm and then slow down the shifter vibrates pretty hard at 3000rpm, but then goes back to normal at 2800 rpm. This happens practically every time I let the engine slow me down to 3000pm, but I haven't found any answers.

Any ideas out there?

 

The only time that happens to me, is when i let go of the clutch too fast ...

 

I don't think I'm letting it out too fast because I'm just moving up maybe 30 or 40 feet. I'm not letting it slip the entire time, but I do slip it a bit because I don't want to take off, but I'm off the clutch before I get to the next car.
