Hey everyone, new to tuning and hp tuners.
I have a r2.8 cummins with an 8hp70 out of a 2016 ram ecodiesel and the transmission is in limp mode and not sure how to get it out of limp mode. I have tried clearing diagnostic codes hooked up to the laptop and also from a code reader but no luck. Anyone have any ideas where I can go from here.
The tcm is a PCS and it came from sound german automotive.
Thanks in advance
