I have been reading these forums for quite a while (while I'm waiting patiently for my 300C SRT8 to be built (living in Minnesota, I don't want mine until April or so)). I used to hear (see) lots of complaints about the hesitation in the 1-2 shift, but lately I haven't heard a peep about it. Does that mean that the TSB everyone was talking about worked (and all newly built cars don't have this issue)? Or has everyone dealt with it for so long that you don't even notice it anymore (though it's still there)?

Just curious,

The 1-2 issue is caused by a number if different things. Most people have found the fix in the TSB Flash, while some have had sensors and throttle bodies replaced. Mine has the 1-2 issue coupled with a stalling condition. My 'fix' should be throttle body replacement. (Flash did not work... TCM replacement did not work... and now I have the P2138 code which ties to the ETC System... so the throttle body is the next step.)

Some have it... some don't, but regardless a good service department is key with any issue.

Mine was reflashed and it didn't help at all. I contribute the problem to my engine is soooo strong that the computer can't keep up with it. I guess I'll have to live with it.

not here

our car has never exhibited this behavior.

Note that forums like this one never talk about the good cars that have no problems and can lead you to believe that all problems are widespread.

They're not all problem children.

In manual mode there is a delay. You can't wait til 6,000 rpm to shift. The delay will cause you to hit the rev limiter. With a bit of practice you anticipate the shift and manually shift at about 5,500 or so and with the delay it will shift at about 6,000. So part of it is a learning curve. When this car shifts the computer is doing all kinds of stuff in the background (torque management, cutting off spark or fuel or both? etc). The result is that incredible sonic FWAAH when it reignites in the next gear. If it didn't do all that we'd be banging (literally) into second and third and the tranny and rear end would be feeling all that HP and Torque at every shift. All this computer intervention may be annoying to some of us, but I bet it adds a lot of years to the life expectancy of every part from the tranny to the rear wheels.

Do not hesitate to approach service dept. a second time

My SRT8 is one of the cars the TSB applies to - built March 2005.

July 2005 after running it in, I noticed a severe case of WOT 1-2 hesitation when trying to run a sportbike at the lights ( Statistically I knew I might not win, but I also knew we both would enjoy it! :naughty: ).

In August 2005 the 6000 service came and I asked the Service Manager to apply the TSB 18-031-05.

My copy of the 1st service invoice shows:

CHECK CAUSE OF ENGINE HESITATION AT W.O.T. SEE-- TSB 18-031-05
081950590 Reprogram control module - check and adjust.

Anyway I did not work. I could not tell any difference when driving, and the 1-2 WOT hesitation was still there. Car was still very quick, and I was busy, so I waited till early November to have the next service work done, and to reapply the TSB - their response was "not a problem - sometimes the TSB flashes do not take".

My 2nd service invoice shows:

A REPAIR FOR HESITATION -- TSB 18-031-05
CAUSE: REFLASH

081950590 Reprogram control module - check and adjust.
1 4669020 LABEL -AU
1 4275086AB LABEL - GENE
FC:15
PART# 4669020
COUNT: 1

Immediately after this, the car drove like it had lost 500-1000lb of ugly fat. It is now has a "friskier" throttle responce at all RPM, and the WOT 1-2 change is now smooth, and virtually seamless.

For those who still have 1-2 hesitation, here is a precedent, with which to approach the service department for a second look at it - you won't regret it.

EDIT. New cars should not have any WOT 1-2 shift hesitation as they will have the latest software.

Anyone know when this running change would have been made?

 

[vvv90]

Thanks for that info Zilla, I had the flash done a few months ago and it did NOT work for me either. I'll try to get it done again soon.

 

[dacbeth]

Mine was built August 17, 2005 and it had the hesitation. Had the flash, but am not sure if it is fixed.

Winter is here, and car has been setting in the garage keeping warm.

 

[Johnny Vig]

for whatever reason i haven't had the issue in a long time. i have been running it pretty good too :wink1: and it only happened once in auto-stick, never while it was in drive. Maybe it outgrew the problem....who knows.

issue or no issue

I have never noticed the issue with my SRT8 with build date of 8/25 . How noticible is this delay? As I have been practicing launching the vehicle, mainly now with the ESP "all off" of the 3 way switch, believe I would notice an obvious delay.

Does the delay only happen in manual mode? In manual shift mode I see this delay without a doubt. Yes, manual mode shifts so late that I dont even try it as it would just be guessing on each shift.

Is the delay only with ESP on? With ESP off, tire spin is the hard part of the launch, but definitely a noticable improvement in torque, throttle response, shifting and 0 - 60 times.

I get a 1-2 shift hesitation with my 300c. I know of the TSB for the srt but haven't seen one for C. It seem to be happening more lately
