Hey all,

I'm just curious if anyone else has noticed this. I have an 06 300c, and when in drive, when the car shifts into 3rd gear, if you do not stomp the gas, you will notice that the RPMs drop down even though you are hitting the gas to accelerate, and then they go back up after a second or two.

I had an 05 300 v6 3.5L model that I traded in, and this car had the same issue also. I contacted Chrysler when I had the V6 model and they stated that this is normal.

I'm just assuming it's the same on the 300C also. Can anyone confirm? Is this a problem, or is this normal?

Thanks

What you are probably seeing on the tach is the lockup torque converter engaging or disengaging. On older automatics it was either locked or not so it was more obvious. On the modern automatics like ours, it is a gradual engagement, kind of a controlled 'slip' , if you will, so as not to be so abruptly felt.

ALso since you notice this during a shift, it's possible you are feeling/ seeing the computer momentarily reduce power to make the shift smoother. There is no throttle cable attatched to the gas pedal; all you are doing is telling the computer how much throttle you want.... IT makes the final decision on how much throttle you actually get! :wave:

I get the hemi hesitation too. Wish it wasn't there. The lag/hesitation is similar to a turbo lag. From what I have read, the torque converter is the likely suspect. The lag is bad enough that I always find myself anticipating the lag and having to plan my quick moves to make sure I not puttering out at the critical moment. While the trannie is good is some ways, it is awful in this area.

Yup, the soft slow shift, I hardly notice anymore. I hear the Jetchip does away with this, as I'm guessing the Superchips and Hypertech programmers will too. If you go reallllly slow you don't notice (who does that?), or if you're romping it you don't notice. So, romp it! :silly:
