If you haven't had the recall done for the TCM and mounting bracket replacement, that should be your first course of action. This is almost certainly a TCM-related issue.I just got a CEL and message "Auto Stick not responding" ('13 w/63k)... the transmission was not shifting as it should (very late to up or down shift, or not shifting at all)... if I accelerated slowly, and eased off the gas about when it should upshift, it would, then smoothly back on the gas to avoid a potential downshift... after shutdown and restart, it behaved fine, but the CEL and a "Service Transmission" remains.
Will see what the dealership has to say after power returns, post hurricane IRMA.
My shop guy seems to think there is a recall for TCM replacement, separate and after the TCM bracket recall, but the main FCA dealer service line says nothing after the bracket recall.
Can anyone shed some light on this?
