While on a 6 hour trip home the trans went into limp mode twice in the first two hours only while using cruise control. Stopped using it for the remaining 4 hours and didn’t happen again or since over the past week. Pulled over shut off and turned back on after a few seconds and would run fine. Threw no codes or lights ever. Trans temps were and are consistently 165-170. Truck is d/t with unknown tunes, 53k miles. Fluid doesn’t smell burned whatsoever. Gonna get a scanner and see what’s going on but anybody have any ideas? Any suggestions would be greatly appreciated. TIA!
