i think it is of turbocharger underboost or overboost but not sure
Trans goes into neutral
all you can do @ this time is to drop the pan, drain the fluid, clean the pan, magnet, etc., install new gasket & filter, refill w/ the correct trans fluid, donot overfill !!!!!!!!!!!!! check for loose shift rods, adjust as required, check the lines for leaks, maybe replace neutral safety switch, see if it improved or fixed your issue ! other than that, you may need a rebuild ?????? torque converter & or pump could be ready to go ???? inside trans . have a trans shop check it out, at least thats free !good luck
What does the code P1133 mean
Code 1133 is when the O2 sensor in front of the catalytic converter on bank one does not switch back and forth between rich and lean.The problem could be a faulty sensor or something with the fuel mixture. The sensor would need to be tested.
Truck wont start
No idea to be honest ,this is the sort of job i need my head under the bonnet and all i can suggest is to call a local mechanic to have a diagnosis ,try the spare key first though in case the chip has dropped out of the key or its been de-magnatised by a mobile phone in the same pocket or stood on top of a microwave
