Hey guys, im having an issue with my 2018 freightliner cascadia 125 automatic. when i put the truck in drive you can feel and hear the gears switching, however the truck isnt throttling and doesnt accelerate (obviously). I am wondering if its the throttle position sensor, or would it be something else? I had the same issue the other day but when i turned the truck off and turned it back on it put in drive and it accelerated. but now when i try and do it it doesnt seem to work anymore.. can anyone help?
