If you do alot of quick shifting between drive and reverse you may want to fork up the dough for an extended warranty...
The computers obviously control so much with our cars, they are usually finding out what works better as far as programming so reflashing is generally a good thing.
Whne i brought my RT in for service the day i traded up for the BEE it was because my warranty was nearly up and i intermittently got a chug chug chug when turning the ignition and it wouldnt fire up - i figured it was mechanical, like a starter or alternator or something...they reflashed the pcm and tcm and called it problem fixed (as an example of how significant the pcms are)
