a different shift hesitation...

[Gilgamesh]

Hey just going through my check list of things I have found 2 more problems. One My car likes to hold gears alot longer than normal. So much that she will rev, even when drove very easy to almost 3k before shifting in automatic. THis is not in every gear and seems to be particuarly persistant in the 3-4shift. Before anyone asks I did indeed remove my raised shift points paramater and the situation persisted.

More disturbing is that I have adopted a very large and noticable "hole" in my shifting from 3-4. The car does not have a seemeless shift like in every other gear but instead seems to hang out in N for a split second before going into 4th. This is perticuarly noticable under any kind of aggressive acceleration and is present in both automatic and manual modes and actually causes the engine to rev higher in between the gears. Yes you read that right, the car almost seems to drop 3rd go into N rev up and then go to 4th. VERY strange and unheard of before my CMR. Anyone else have this??? or know what it might be??

I get it sometimes too...like going 70-80 on cruise down a slight hill the car will all of a sudden go to 3000 rpm and then stay there till I either disengage cruise or it fixes itself after like 5 seconds.

This almost sounds like what JMatt and SRT Hardware are experiencing. Similar horsepower numbers as well.

I get that, and it is definitely tune related...I've been changing tunes lately and though I can't match up the tunes with the effect, I do know that special feature comes and goes. It is currently in effect.

I will be one happy geezer when some brainiac figures out how to whip the TCM/PCM/FCM into shape when it comes to shifting that NAG under power.

I think JMatt has this issue and he does not have a CMR tune. The one thing you guys seem to have in common is that you are all BIG horse power cars. Just me thinking out loud. Hope we find out what the issue is.

FlyByU: I see you flew by me on the TS database. Hats off.

Oh, wait, what's that rumble I hear in the background? Could it be The Red October manning up?

Could it be?

Yep.

I'm going to do my best to give Bradenton a try on 8 May. A lot of stuff has to work, though, and you know how that goes.

In the meantime, I wonder if the LX Nationals could come up with a class I could dominate....something like....Red Magnums built in 11/05 with exactly 26,458 miles on them at the start of the competition? Whaddya think?

I think you are dreaming, but hey, thats just me

Exact mileage...are you trailering your car there?

Doesn't work like that.......good try though.

thanks I just wondered because I never had it with my B&G flash...

Noticed the same thing here today on my 2008 5.7L using the 91 Perf tune. I thought it was some sort of MDS thing but verified that my MDS was indeed turned off which I set to off with the Predator when I installed the tune.

I have also lost the abliity to use my cruise control at all. It just wont come on....anyone else have this??

I had the same problem with my car but I fixed it. It was the disable auto upshift setting on mine. If you are using the disable auto upshift go back to stock setting and see if your problem doesn't go away.
