The biggest thing you should control is how high you rev the engine when you slip the clutch in 1st to get moving. When learning, just hold the engine speed at 1-1.2k rpm and slowly engage (releasing the pedal) the clutch. As the vehicle starts to move forward gradually increase the throttle. When you're proficient you won't have to put any thought into this process.

The other thing about shifting that a lot of drivers (even experienced) make is that they only rely on the clutch pedal when engaging after shifting. Remember that there are two things going on. The engine has a speed it can spin at, the transmission has a speed that it can spin at. When the clutch is engaged, they're both at the same speed.

When you shift don't let the engine speed drop all the way down and then have to come back to the speed it would be at for the next gear. When you push the clutch pedal in to shift, you're off the throttle completely (both movements happening at the same time). As you're about the engage the next higher gear give it a little gas as you slowly release the cluch pedal. This will make transition into the next gear seamless by having the engine at the speed it should be at for the next gear. Hope that made sense. Congrats on picking the right transmission. :thumbup:

Thanks good tip. In my current driving style, I have been reving, holding about 2k rpm before engaging the clutch. I notice sometimes when I need to merge or move quickly that I will hold to about 3k, but only on rare occarsions will I have wheel spin, but only lightly. I was playing around today with quick revving and then engaging the clutch which seemed to be a little bit smoother.

2k is too high, 3k way too high.

Again, this may be a problem with the car itself if it has the same gearbox as the G35.
When you bring it in for service ask them to check for any TSB or whatever for the clutch/gearbox. I think Edmund's G35 had a repair that made the clutch much more manageable.

I will have them check the clutch when I go in for an oil change in a couple of months. I also noticed some odd clunking, shuttering from the clutch.
