I wanted to post this to this forum because this is the only forum i have seen anyone talk about this.
I have a 392 Daytona Charger, and sometimes when i go to up shift with the paddle the car will downshift instead.
I took my car to one dealership and after looking at it for 3 days the service guys told me that the up-shift is on the right and the down-shift is on the left and they couldn't find anything wrong with it.
Today i took my car to another Dealership to have it looked at. The mechanic told me, that after researching the problem, it is a standard problem on 392's and hellcats. He said if you up shift, to quick the car will interpret the up-shift as a down-shift because the voltage from the up shift is not high enough to register as an up-shift. And that it is recommended to hold the paddle for more then 1 second. There is no fix for this because it is driver error by not holding the paddle shiftier for more then 1 second.
I just wanted to post this for anyone who has this problem. Its not a fix but at least you can know what "Dodge" says about the problem.
Welcome to the forums...
With your interaction with this Mechanic, did you get the sense that this was what Dodge told him, or might it be the case that he fed you the line to fill in a lack of solution?
