I've been reading around after expierencing a hessitation, when the trans was going from 2-3 last night at the track. I have found a few people that have had the same problem w/ thier 07 and apperently there is a flash coming out.:confused: Has anyone with an 07 received this update?? I am going to talk to a couple of techs tommorrow and see if there is one.

I was just at the dealer last week and they told me there was nothing for that yet,let me now how you make out with your dealer.Kevin....

I found that when I changed my stock air filter to the K&N drop in I noticed a shift hesitation for about a week or 2. Now the computer seems to have adjusted to the slight increase in HP and for the most part my shifts are fine again. Sometimes when it is really cold ouotside, and the hemi is acting like a beast, I'll occationally get the 1-2 hesitation, but ususally after a couple of WOT sessions the trans seems to shift fine.

I can make mine do the 1-2 hesitation everytime if i want. It does it when im driving aggressivly in autostick and I downshift into 1st gear and keep the rev's above 3k and then floor it again. When I do that it hesitates almost everytime. Im going to take the tech guy at the dealer out with me and show him.

Mine is doing it more and more consistantly now, especially after 100+ 1/4 blasts yesterday!

I will call the dealer next week. I am tired of the shifting.

I have an '06 with the TCM update but I can still force the 1-2 hesitation while I have it on the road course here in PA. The auto-stick will do it everytime when downshifting as mentioned above. On the course there is only one turn that I get down to 1st in but it still happens.

I love this car but the tranny needs some love. I am going to keep it until 09 when I will be looking for a change. I am hoping to stick with the GC but I need this tranny to be "on par" in terms of performance.

Had a tech at my work hook up the starscan thing to see if there were any updates for the computer and ...................nothing everything is up to date.
