Just Got Tcm Flashed

**BIGDAVE** · 12-04-2006, 08:23 PM

Let me start by say THANK YOU to Meister for finding the TSB.I found the TSB he was talking about,printed it and went to my dealer.I told them how when getting on the highway (not all the time)the car would shift to first then shift to second it would almost put me through steering wheel .They said they had done a few of these and would see if my car would take it.My build date is 05/04.When they hooked up the star scan the system said this is not an SRT so,the tech checked and in the system there was am update for my TCM(he put my TCM number in).The tech said its not a TSB but an update that is kept quite so you just have to ask about it.This was brand new and mine was done today 12/03/06.
So far it has made a major difference and is getting better.It is still learning and will update as it gets better.

Your car isn't learning while you're here posting.....logout and start driving, man! I want some 411!

I just went for a ride and did a full converter hole shot and did a 40ft John Force burnout.The car pulled so hard that my sun (moon)roof slid open 2in.It had never done that before.WOWWOWWOW!!!

Hey Bigdave, can you explain exactly what your RT was doing/feeling like?

**HEMI~C~** · 12-04-2006, 10:11 PM

Dave, thanks for the update and I am totally jealous man. I spent 2hrs at the dealer today, walking the tech through the update procedure only to be stymied by them not being able to connect to the big Chrysler database in the sky.

I will have to return for the update again next Monday.

I am about ready to jump on the MOPAR PERFORMANCE TCM considering its only a 90 bucks more than the flash!

The update is FREE!!!The service mgr has a code to submit to DCX get it paid for.
Well before there was times when I WOT getting on the highway it would shift down to 1st throw you in the seat and when it hit 5500rpm it would shift and was like I stomped on the brake peddle,almost throw me into the wheel.Then shift and throw me back.Also delay shift 1-2 normal driving.
Hope that helps,BIGDAVE

Well just got home from work and I think its learning REALLY WELL!I was sitting at a light to turn left there was an arrow and the idiot in front of me stopped at the arrow,I blew the horn and just sat there.I said scr*w it and hammered it and did a PRO DRIFT around the corner.I saw a few faces with a look of OH MY GOD!!!HEHEHELOLLOLLOL!!

As BIGDAVE correctly related, bellman, ironically this patch, though developed for the SRT8, hasn't had widespread positive results with SRT8s (works beautifully for every 5.7 that has tried it). The good news is that the soon-to-be-released new patch for the SRT8s supposedly works very well.

Here's the original TSB: SRT8 TSB flash for poor 1-2 shift performance (TSB 18-031-05)

It would certainly be worth a (free) shot trying this patch while waiting for the revised one to come out. It obviously worked with some SRT8s or it would have never been released.

I understand the new 1-2 shift hesitation for the TSB SRT8 is due 12-22-06

About 3 or 4 weeks ago my 5.7 05 "C" faltered for a second and a chime went off and an orange light came on. The next morning I brought it to the dealer and they said they downloaded the latest PCM download for torqe management. On the way home I tested the car out and couldn't believe the difference. From a standing start at idle with ESP off, flooring the car I squealed the tires over 100' and had to let off the throtle to stop the spinning. Also the car was fishtailing. The same start with ESP on still gave me about 50' of burning rubber. Before this download, my car barely would chirp the tires at WOT. The following week I brought the car in for an oil change and asked the service manager the TSB# and he said each vin# had its own TSB# and there was no standard #. All my statement said was a TSB PCM download. The sevice manager didn't make any sense to me. I believe they downloaded something that they didn't want anyone to know what it was.
