Those who got the tranny TSB: Check in here please

Guest · 01-02-2007, 08:00 PM

Ok, so a few people now have the TSB done and have had time to drive with it for a bit. I have some questions for you.

It is apparent to me that my beta program is still a bit different from the TSB that came from it. My car has been running it now for about 6 months. I need some comparative data if you can help.

Out of all of the posts I have seen, I have yet to hear anyone say that beyond the "fix" they felt anything else. Has anyone experienced any true felt gain on their car since the TSB? I don't mean the better shifts relaying better performance.... I mean beyond that.

I have stayed out of a few of the threads because I can't specifically comment on the characteristics of the TSB because I know mine is still a bit different. But here's what happened for me:

1) Not once has it ever tried to cut the throttle on the 1-2 shift in "D". As many of you know my car did it on command (except of course the day the SRT Engineer was here to work on it... go figure).

2) Autostick forces upshift exactly at redline with no loss in power, never hitting rev limiter, and never going into limp mode. Even on my best days I could never consistently shift exactly at redline before my car was reprogrammed... I would say 4 out of 10 times I would bump the rev limiter... so this feature is a HUGE plus for me.

3) Slightly firmer shifts in "D" and in autostick. Response time in autostick is twice as snappy I would say.

4) The one part I haven't spoken much of, and I have not spoken of at all on these recent threads is that I got a tremendous gain in power, and my torque management is greatly reduced. I am aware that this part did NOT make it into the TSB. I believe this was part of the tinkering as the engineer was trying to figure out what was causing the 1-2 shift issue. I have raced other SRT8's, and driven some others as well and I can tell you that the difference is NEARLY as great as hopping from an R/T into an SRT8.

Using my GTech Pro SS meter, and calibrating it twice on seperate runs to assure accuracy, I pulled nice numbers. Far better than I had experienced before SRT worked on my car. Xmas day on cold wet roads with intolerable wheel slippage (ESP ON) I pulled a 13.4 @ 102mph 1/4 mile time. On a warm dry road with ESP off I project that it would have run a full second quicker.

I'm asking about this because I haven't seen anyone say that they felt a real SOLID performance gain other than better tranny characteristics. I don't want to flash my car with the TSB if I will lose this. And if mine is truly still unique I want to keep the flash to hopefully add some value to my car.

Thanks!

Got the TSB Flash done 12/22/06 - same here, haven't bogged at 1-2 since.

2) Autostick forces upshift exactly at redline with no loss in power, never hitting rev limiter, and never going into limp mode.

It may shift at 6,100 vs 6,200 red-line, to be honest I'm usually not watching the tach/EVIC at that point. But its close enough to red-line for me. Agreed, achieved with the TSB flash.

3) Slightly firmer shifts in "D" and in autostick. Response time in autostick is twice as snappy I would say.
I would say that the shift happens much more quickly after the TSB. There are no longer any hesitations in drive or autostick. I'm horrible with judging 100% vs twice, etc. Its just better in my book.

4) The one part I haven't spoken much of, and I have not spoken of at all on these recent threads is that I got a tremendous gain in power, and my torque management is greatly reduced.

I would agree with what you said. I don't think the torque management is significantly reduced (maybe a little), but I feel that how and where it is applied may have been tweaked. I feel that WOT launches from 0-60 are much smoother, I know this includes the 1-2 shift but it also seems the the torque control is released more consistenly or evenly as RPMs increase.

Using my GTech Pro SS meter, and calibrating it twice on seperate runs to assure accuracy, I pulled nice numbers. Far better than I had experienced before SRT worked on my car.

I've said it to you before. DO NOT FLASH YOUR CURRENT TCM!!! If you really want to try this flash, either drive someone else's car to check it out or buy a new TCM and have it flashed with the TSB. You're lucky that the SRT men in black haven't shown up at your door to "re-flash" (erase) yours as a courtesy.
Thanks!

See all the red above.

Still rubbing in it Bandit! ;-o

So do you have any plans on getting it dyno'd to see what the power is to compare? That might give us some more info.

**BigIke** · 01-02-2007, 08:36 PM

AS you all well know I hate my car now, due to the TCM flash. Why did the mess with the auto stick why not just have it shift at 6,200 at WOT in auto and leave the manual a manual. perfomance my have gone up, but fun factor went WAY down. This isn't a fix.

**Husker** · 01-02-2007, 08:43 PM

The flash is awesome! It adds to the performance of the car. I would highly suggest it to anyone.

Please keep your negativity confined the SEVERAL OTHER THREADS you're spreading it on. This thread is not about anyone's issues... there are already conversations going on about that.

Thank you.

I'm trying to gather some data from those who have the flash, and have been using it. We know you don't like it. We get it already.

**Jaak** · 01-02-2007, 09:22 PM

I love the flash... I agree with 1fastsedan. I also wish I could read out Bandits!

Thanks for the detailed feedback, it is really helpful. So you are seeing a little bit of a gain? That's great!

I think that if I ever really need to see what the difference is, I will be doing it ion one of the safe options that you detailed in your post. Thanks again!

Hehe heheeee

Yes, us locals here are doing a M&G w/dyno runs during the Spring, and IF I still have my car then i will be posting all dyno data. IF I end up buying another car I will go and dyno mine before selling it so that the forum can benefit from the data.

I have a couple of other cars in my head (I get bored quickly and am always looking for the next thrill ride) and if they don't flesh out I'll still be happily tearing up the streets in my baby.

Negitivity? It's my opnion on the performance! But hey it's your post. I'll go back to to post I started so I can get flamed there. Thanks alot.

good, thanks!
Bandit, I had an issue two weeks ago where I was on two lane roads attemptig to pass someone, the car kicked down( it was a fricken tractor I was passing, Iowa backroad) and hit the rev limiter and pretty much stopped...mind you a car was coming the OTHER DIRECTION!!!!!!!!!! So far I can say that the shifts are clean and chrisp, or as clean as we are going to see until we get a 5/6 speed tranny. I can run it upto 6100 rpm or so, let off and it stays in 1st...once I past the redline then it shifts..LIKE IT SHOULD..I really like it alot.

**My Hemi** · 01-02-2007, 09:56 PM

Ok i will post my findings I dont drive my car as neerly as much as most other SRT owners...I bought the car Aug 8th 2006 i now have 2153 miles on it....

I had the Flash done on Dec 27th.2006 ....When i picked the car up i knew something felt different right away....The shifts seem faster ...firmer,maybe its cleaner of a shift....In auotstick it will shift just before redline which is about 6200 rpm in my car...the 1-2 hesisation isnt there anymore.....In D it seem more responsive to what i command it to do...Now as far as power is concerned...I think it has way more then it did,in matter of fact kinda too much now...LOL it will take me some time to adjust to it.....If left in autostick it and you break the tires loose,it does upshift pretty quick into 2nd...thats me driver era i will have to get used to it....Its cold up here around 40's at nite so I think that has alot to do with it also....I have F1's and they are pretty slippery when its cold out.....
The other day i had it in "D" and i got on it and it really suprissed me on how it moved out very smooth and powerful...I am glad i did the Flash ...The only draw back i see is that it did give it more power ,,,,the rpm's seem to move like lighting compared to when i bought it....I cant wait to try this at the track..Im hoping it will give it a little better ET's then what I previously posted...I hope that helps......

Took the car out for a quick blast with the data logger on it. Not enough data to really show yet, so I need to do more runs. Highest shift point was 6107 RPM, but I want to run it with a faster update rate next time to make sure I'm not missing data.

Are these tests done in auto or auto stick? thanks
