1-2 Shift Hesitaion

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.
