I am not sure if this is the right fourm for this, but here it goes anyway. When I get in my IS in the morning it doesn't like to shift real smooth for a few minutes. After it gets warmed up it seems to be ok until I jump on it. It goes to 4,000 and doesn't want to shift and then it will shift real hard. Now it doesn't do it all te time, but I was wondering if anyone else have or had this problem and what can be done if anything to correct it.

I did see an SRT chip that was on E-bay that was said to take sluggishness away. Is that true??

Thanks,
Mike

Its happens more during just normal driving. For example, if I come to a stop sign and start to go again, then the cars doesn't want to shift correctly. It may take a couple of seconds to shift into second.

Does that help??
