For those wondering, the TSB on the TCM is still available. Here are my results, as posted in the "tcm tsb pulled" thread:

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 on track results!

Hope this thread helps those who are contemplating doing the TSB for the TCM flash, I know I am loving it.

Thanks for posting such a detailed write up.

sounds very similar to what my 07 does. I wonder how different the TCM is versus te stock 07 program

I believe the reason the TCM does not apply to the 07's is because the problem was (or should have been ;) ) already fixed at the factory.

I had the TCM TSB done today. Big improvement. My experience is similiar so far to the first post in this thread. Only put 10 miles on her and it's raining today so can't have too much fun. I highly recommend this update if you have an 06.

timster or other '07's
Does your '07 shift that early (5600) for the 1-2?
Does your '07 shift at 6100 in auto stick?
As a build date of 8/31/06 (must of been one of the 1st '07's) mine sure does not shift like the flash.

We need some comparison 1/4 times(before & after) if anyone can provide any.(even g-tech) I have searched all over and there seems to be mixed results. LX SRT8's actually losing 2-3 tenths after the flash. Like I said, some are happy and others are not. I am running high 12's without it, so I'm staying on the sidelines for a while.:)

My 1-2 in auto at wot is at aprox 5600 give or take

in autostick all gears shift automatically at 6100

my build date was late september

gculver,
In your sig you have "(MODS:MODIFIED AIR BOX/TUBE WITH HEAT SHIELDS,IAT SENSOR SHIELD, T-STAT,EXHAUST)"

Is the air box / tube the same as Sarge & Claude's? With heat shields???
IAT sensor shield? Did you relocate it AND fabricate a shield?
Are you using the 195 stant stat?
Corsa exhaust?Great times in the 12's!
Bill

How long did you spend at the dealer for this?

No more than 45 minutes. Actually, the DMX printout for this flash upg states; 3/4 of an hour. I actually printed out and brought the download instructions to my svc mgr.

What is the TSB number for this?

What is the TSB number for this?

See attached...

staff,

The number is; 21-020-06 // Group; Transmission // Date; 12/20/06

good luck, I am very happy with mine and noted it in other recent threads.

Bill, Don't know if its the same are not, I have experimented with several setups. Fabricated factory top box with inverted cone filter, bottom cup in,bottom cup out, stock tube,non-stock tube, shaved snorkel,heat sheilds,various t-stats, etc.(you get the idea). All sheilds are fabricated, stock IAT location(you would have to locate it in top air box to do any good(thats way I use sheilds-at least for now),12.9 run was on stock exhaust, stock PCM,shaved snorkel,slightly modified airaid tube,195 stant and sheilds.@60F.I'm trying new setups frequently in search of consistent mid-12's in the texas weather. Hope this helps.

Thanks guys, I love this site.

My gas mileage dropped from 13.3 to 12.8 since the TCM update. The TCM is a major improvement but there is still alot of room for more improvement on how this vehicle shifts. I've only driven it about 200 miles since the update and have retired this vehicle from daily service due to the poor interior quality. Will sell soon :(

I have to wait another week for my TCM upgrade. I waited there for 40 minnutes the other day so they could download all the softwarre and get the update ready...then with all the Joe's twidling their thumbs in an empty service bay....they say nothing can be done until next week -- schedule is full.

HA Bunch of jagoffs.

Nobody wants to get an hour warranty pay for 10 minutes worth of work.

This is why nobody likes the stealership.
