For the last few days my truck has died when I put it into reverse and only sometimes. I have the edge insight on board so I run the code check and clear all codes every few days, I am also chipped with a hypertech(garbage but got it for stupid cheap) so it throws codes. And only because I have had a CPS issue before I figured that when the code was thrown that's exactly what it was but I do believe that I was wrong.
First thing this morning I replaced the CPS and did a needed oil change and when testing the truck out before doing a fuel filter change it still died out. Now when I say it died out I mean it shut down immediately, no revving helped before and as during shifting, it doesn't matter the temperature of the drivetrain or ambient temp, and the TC is pretty new with less that 30k on it, fluid is pretty new with about 5k on it and filter since I did the special flush not long ago and ran about 20+ qt through it. I have been reading forums all morning but can't seem to find my issue or answer.
Any suggestions as I am abut at wits end with the things,
With the new CPS it now dies every time and not just sometimes. I am using the light grey CPS btw, my buddies and I have always had the best luck with them. I bought two, one to use and one to keep in the glove box with a 10mm just invade there is an issue on the go so I suppose I can try that one and see what happens.
It sounds like a transmission issue.. Pull your Trans pan and I bet the filter will be laying in the pan when you pull it. If so change the filter and put new fluid in it then check again..I would highly recommend you do this soon because you are sucking air instead of fluid and can damage the transmission.
