Altering shift patterns
Are there any aftermarket devises to alter the shift pattern? 2003 1500 4x4 5.9. Really do not like the general function of this trans. If I shift it manually it is much better.

Disconnect the battery to reset the PCM.
It will take a few weeks to 'learn' your acceleration rates an tune to your driving mannerisms. Of course if you lay on it it will shift at the predetermined limits.
