I think the problem is going to be doing this without a transmission tune.
I assume you don't have\use a tune?
My guy said to apply the stock tune then flash my TCM. Then apply a Diablo tune (assuming it works) and then I will log and he will see if my original tune can get adjusted and re-applied else he will make a new one based upon the TCM post-flash.
Just using stock flash files no tunes.
Installed the old dial shifter again and adjusted the BCM setting accordingly.
Setting changed in the BCM. ( May need to be 2021 or newer. Confirmed working on 2022 and 2023 BCM's. )
Paddle Shift Feature Present: Yes
Paddles Lock-out Feature Present: Yes
Shifter Type: 4 pos Rotary Eshifter PRND DS (RS4) (Not needed if you always had the dial shifter)
The cluster may need to be a 2021 or newer to display paddle messages and current gear properly.
Steering wheel from a GT or TRX. Not sure if paddles can be retrofitted easily to other wheels.
TCM or TCM flash with paddle support from a stock Ram GT (BSG only), stock Wrangler 392 (WOT not up shifting issues) or maybe a custom tune??.
