I read that the DCX pulled the TCM upgrade already, and a new one is coming out next week! anyone no anything about this and why!

Don't tell me this. I just had that TSB done this week.

Where did you get this info from? I have an appt. to have the flash done on Wednesday.

I hope I can post this here but I got it from ***********/forum its under the Jeep area and the listing is the 1st to 2nd flashing. Good luck! I have a app. for Tuesday.:eek:

mine is this monday! it better not be a waist of my time to go in

Any more news on the TSB being pulled? Fact or fiction?

I got mine done this week and I still have a hesitation in 1st to 2nd gear shifts. Anyone else have this problem

The only problem my '07 TCM has is that it shifts from 1-2 at 6100 or 6200 rpm and I believe it then hits the rev limiter and has the hesitation or stumble. I believe that I will just get the stage II PCM from B&G as I do like everything else about the TCM.

yep customers 07 has the same problem... everything else is great

I'll take a guess since I had the update done a few days ago. Mine shifts better now and upshifts at redline in manual mode BUT (big BUT) it still exhibits the same "hitting the rev limiter" problem that the TSB was supposed to fix on WOT downshift then upshift (with pause). I haven't reported this to my dealer, as I just discovered it today but it's obvious to me the software still has problems. This problem doesn't bother me too bad but it should be fixed eventually.

Just had the TSB done to the beast. It is still available. I just gave the service manager the # and he asked if I really needed it. After I told him, I wouldn't be wasting my time if I didn't, he took care of it within 45 mins.

I just now made the appt for tomorrow at 7:30am, after breaking some chops with my svc guy - does it do what it is supposed to do?

Thanks for the update, I drop mine off this afternoon.

I'm going to let the dust settle before I touch anything on my 07. Plus its not clear anywhere from any site if the 07 sees any improvement. most of the reflashes have been done on the 06s.

The TSB is only for '06 GC's. http://www.wkjeeps.com/wk_tsb.htm

the 07's are fine. i raced a 06 that didnt have the flash and spanked him. it makes that much of a difference.

Keep driving it....put on more miles and drive it aggressively doing manual shifts and downshifting into turns and holding shifts until 4,000 rpm.....if you can. When you brake hard down shift 4-3-2- and if time and speed allows 1st. Trust me within a few miles the tranny will start shifting like you. Treat it like its a manual 5 speed and it will start behaving like one.

The one thing they did not tell you to do is get the "adaptive" side working the way you drive. My AMG E55 has the same transmission. The valve body was replaced and the mechanic had to drive it to set the adaptive parameters. They also told me to drive it using the manual shifting to get it to "adapt" and record your style of driving.

sweeet!! That's what I like to hear about the 07. will need to find an 06 w/o the flash to test it out

Just came back from dealer this AM with the flash upgrade on my '06. Ran it on parkways and side streets in auto-stick as well as full auto mode. The very first time that I pushed 1st in auto-stick, the "rev limiter/upshift" sign came on. It DID auto **** into 2nd immediately afterwards. From then on - it automatically upshifts into 2nd and so on with no panel indicator. Also in auto-stick, I get 1-2 at about 7100 RPM's. The svc mgr told me that it is okay to "push" the RPM's in auto-stick (to the limit) for about 100 miles or so as it helps break in the new software fix the way I would like my tranny to respond from then on.. Sorta like how we "broke" in our engines when we all first purchased - the more aggesive we are with our jeeps in the beginning, is the way they will behave for us. It is 'supposed' to have more power shifts AND run more efficiently. The whole process took 20 minutes at the dealer.

Also in auto-stick, I get 1-2 at about 7100 RPM's.

You meant 6100 RPMs, correct? Thanks for the update.

HELP! I took my 06 in for the TCM flash today and a slow tranny fluid leak. The service advisor just called me and said "before we do the TCM reprograming, I just want you to know it will make the vehicle slower so are you sure you want it?" He could not explain what he meant by slower and I really have not noticed the 1-2 shift hesitation so I decided to wait. Can anyone who has already done this advise? Is your truck somehow "slower" after the flash?

OOOOOOOOOps - I guess I am too excited - correct - 6100 RPM's.

Well, I just put on about 60 miles in all types of road scenario's and I am NOT AT ALL expieriencing any reduction in speed and/or power since this AM. In fact, I feel that the tranny is deffintely shifting smoother (full auto and auto stick) and I sense more power, I guess from getting more RPM's per gear, partucularily from 1-2. This concerns me because according to the service bulletin write-up, this software download is "irreversible". Can you have your service mgr really define what slower means...?

Also, while I was waiting at the dealer, I was chatting with another '06 GC SRT/8 owner who had his done last Friday and he was very pleased with the upgrade since then. He was there today getting some mods done.

Thanks, I will call my dealer back and see if I can beat any more information out of them.

Well, the dealer just called me to tell me my truck is done (for the tranny fluid leak) so I asked them again why they think the TCM flash makes it slower. They said they did the flash on a 300 SRT8 and that customer said his car is much slower and he is very unhappy so they are warning everyone. I still don't really know what to do. I don't have any shifting comlaints other than the "will not downshift far enough at 35 mph" problem others have mentioned. I guess I will just follow the threads here for a while before finally doing anything (chicken).

Here's a thread you might be interested in. Maybe the example your dealer mentioned was for someone who judged the flash too early or didn't drive aggressive immediately following the update for the tranny to re-learn properly?

I'd find another dealer who is not so dumb. So based on what ONE of their customers are saying they are telling everyone else that the Flash is going to result in a slower vehicle?? Hogwash, THE FLASH WILL NOT RESULT IN YOUR CAR BEING SLOWER. PERIOD.

That was me.....as soon as you get it flashed you need to set the adaptive parameters. If you drive like grandma its going to behave like grandma.......if you drive/shift it like you stole it......its going to respond and give you what your looking for!

Another stealership that has no clue!

Fellow enthusiasts;

I just went 50 more miles (aggressive and in both modes). The Flash works GREAT. The net message is (just like my service manager recommended) that you have to really burn in the software from the onset so that it seats properly. Unlike a hardware upgrade, software developes a "driver" memory so the more you work it out, the better result you can expect.

I picked the beast up this afternoon, The TCM was done and have the paperwork to prove it. My tech drove the car about 10 miles to help set it in to get the most out of it. He said to drive very aggresive for the first 100 miles. I drove the tollroad home and it shifts very quick and qrisp. A big difference. :eek:

It would be nice to know the build dates after which we would already have the new software in our 2007's.

Dealer just called me to let me know my truck is all set with the flash. I'll be picking it up soon and I'll post results.

I also feel your pain. My 07 has the same problem as most of the 06's in the 1-2 shift. ARGGGGGG, sucks when you punch it and the shift throws you forward.....

I had the flash done yesterday and I have owned the JEEP for almost a year (8,500 miles). You have to get this flash!! Hitting 2nd with the autostick in 1st is a huge improvement IMO. Also, the 2 - 1 downshift @20 mph is "as it should be". On occasion it still bogs its way in 2nd - but if you authoritatively stomp on it, it'll downshift. Autosticking to second without hitting the cut-off is downright strange (in a good way). Imagine - hitting second with a kick in the a**. The MOPAR/Corsa set-up has a slightly different top end snarl, with a shorter, sharper, more staccatto Burp (Fart).

This was my second time in two weeks that I tried to get the flash. The first time it didn't "take". Yesterday, the dealer informed me that the flash was indeed pulled and replaced with a new version. From what I've been reading around the web, I believe them - they brought this issue up, not me, so they got this info from Chrysler when they went to source the latest flash from the internet.

In my opinion, the truck needs this flash. I can't think of any situation on the street or strip where the old flash will have an advantage - IMO. Good Luck.

The real question is do we have anything to lose getting our '07's flashed anyway? We will just get the same software that all the '06 owners are all raving about. Not sure if there is a downside... :confused:

Amateur Threesome (http://www.****tube.com/categories/75/threesome/videos/1)

in auto stick, mine still gives the upshift warning before it shifts automatically.
Is this right?

Had mine done yesterday and the up shift happens about 5900 rpms as far as a can tell and I get no upshift warning light. All is good.

OK, here are my results, this is how the truck should have come when I bought it! I ran the truck hard for ~50 miles so far and here is what I have noticed on the shifting, all of these are with traction control on (enabled):

In "Regular" Drive (D) Mode:
From a dig, the truck screams forward like before
1-2 shifts at ~5600 RPM with nice ass-kicking pressure behind it.
2-3 shifts at ~6100 RPM with the same pressure felt on the 1-2.
3-4 shifts at ~6100 RPM with a softer pressure thatn the previous gears.
4-5 shifts at ? because at that point traffic was coming up quick.

Downshifting is the same as it was before.

In "Auto-Stick" Mode:
From a dig, the truck breaks the tires loose (with traction on) and lunges forward like it never has before.
1-2 shifts at ~6100 RPM with nice ass-kicking pressure behind it.
2-3 shifts at ~6100 RPM with the same pressure felt on the 1-2.
3-4 shifts at ~6100 RPM with the same pressure felt on the 2-3.
4-5 shifts at ~5900-6100 (hard to tell) with same pressure as the previous gears.

When downshifting manually, the pressure it applies the gears is enough to jerk you forward, so my guess is that the pressure is increased on the downshift in "Auto-stick" mode as it is on the upshifts.

In auto-stick mode the truck shifts up for you to the next gear through all the gears, and my SHIFT UP indicator still displays on the instrument cluster, but only under WOT conditions. For example, if I just gradually take it to redline, it doesn't say anything, when in WOT, it tells me to SHIFT UP everytime.

I am extremely excited with this flash, because when I ran my 13.5 my truck bounced off the 1-2 AND the 2-3 rev. limiter, and took forever to go into 4th gear (at least a second and a half).

The truck is still stock and I cannot wait to get back to the track when it warms up here in Michigan. I'll keep everyone posted.

This is definitley not how my 07 runs --when you say the pressure is pretty much the same between all shifts thats not how it feels for me, its noticebly softer after the 1-2 shift, even at wot......

Right, but is there a delay before it shifts? My '06 was taking 1-1.5 seconds to shift between gears. That is why when I ran at teh track, my car bounced off the rev. limiter a couple times during the pass.

Oh, and FWIW - I went ~60 miles and the truck drank a half tank of gas. What is that, roughly 6-8 MPG! :-D I have been driving like an ******* today. Hope that "adaptive" part of the software picked up on my driving methods, cause more of driving like that might get expensive. LOL

when youre saying 1-1.5 sec shifting between gears - do you mean like slowwwly shifting into the next gear like its almost slipping into it instead of a nice crisp shift ? if thats the case than it definitley sounds like my ride

Yes, that is what mine was doing. Just wanted to make sure we were on the same page.

Luan,
Does it shift automatically in autostick from 1-2 or are you timing this shift about 500 early? My early build '07 definitely has the neck snapping HESITATION.

Hey guys,
I have been lurking and reading but not posting. Have learn alot about this beast from all of you and I now have a questions to ask.

I had the flash done yesterday and in autostick mode it still hits the rev limiter. Is this normal until the TCM adjusts or did the flash not take? It seems to me that the trans automatically shifting in autostick mode after the flash was immediate or am I misreading what is being said. I want to make sure that I am giving it enough time or not missing something before I call my dealer again and have the flash redone.

They did not perform the flash properly. Take it back and have it done again. The autostick feature should work immediately after having the flash performed.

That's what I thought. Thanks for confirming for me.

I hate how the new autostick programming shifts automatically. How is that "autostick" now? I guess it's better than the old hesitation, though.

The 07 SRT8 Vehicles all have a different programmed PCM. This works with the TCM, therefore the TSB is only for 06 0r 05 models. Mine shifts at 6100 (1-2), 6200 (3-4) others? This TCM is going to be released as a Mopar Performance Part? (Heard this but have no proof) I haven't tried Autoshift but I'm sure it also shifts at redline. I've found no advantage to using autoshift as drive does the best time slips! My JGC is an 06. My findings after about 2500 miles on this mod. My throttle response is much better too, even after granny driving, a great improvement in MO. Gene

Put it in "Auto-Stick" and it will automatically shift for you into 2nd, 3rd, 4th, etc. Now the difference in auto-stick and regular drive is that it will not upshift for you unless you hit redline, so if you romp on it in 1st and stop at 4000 rpm, it'll stay in 1st. If you re-romp to redline, it'll shift for you into second, then stay in second, untill you either shift up on your own, hit the redline in 2nd, downshift on your own, or come to a complete stop.

Thanks General Confusion

Since last week I have been training my trans as you suggested and it has had a very beneficial affect. I get shifts much more the way I want them. My trans is now much quicker/more likely to downshift when I floor the accelerator, especially second down to first.

Thanks again!

I'll be having mine done tomorrow.

I went to the dealer yesterday, he did another reflash for the Jeep. I had it done 3 weeks ago and he said there was another one.
