'06 Charger SRT8 3-2 downshift rough

[rodneyiii]

With the 93 octane CAI tune loaded (only one I've tried), I get a rough 3-2 downshift when in Autostick mode. This happens when I slow down and let the tranny decide when to downshift. If I make the shift myself then the transition is not as bad. The tranny downshifts smoothly in Drive mode. If I remove the tune, the 3-2 Autostick downshift is glassy smooth. Is there something in the tune that can be tweaked to cure this issue? I've got the latest PCM & TCM software and am running the Predator v.9r12 software. Thanks.

I would try to reset the tcm apadtives in quick adjust to see if that cures it. There are no specific changes to be done for that nor are changes done FOR that in the tune files.

I reinstalled the 93 CAI tune, reset the TCM adaptives, and also had the tranny fluid & fliter changed (it was due anyway). The 3-2 downshift bump still happens but only with the Predator tune when in Autostick mode. The factory tune is still smooth. As noted above, it only happens as the car is slowing to a stop and the tranny downshifts (about 10 mph) on its own.

This happens on my R/T as well. Hard down shifts from 3-2 when the tune is loaded. Is there Line pressure differences between tuned and un-tuned?
