I totally agree. But I don't have a schematic to troubleshoot the system. I've cleaned the big connector on the passenger side wheel well. This seems to control everything with the tranny. I clear the codes, but the tranny still acts up. I've done this at least five time today. With very low mileage on the truck, I can't believe that I'm having an issue. Really pissing me off! I need to know what connector go where, for tranny function. Locations on the truck and what readings I should get with a digital volt/ohm meter.
