replaced trans temp sensor, same prob.
my 06 4x4 has been giving me some odd problems this week. starting with a 'check trans temp' warning. then tbc fault. then a rf wheel speed sensor. long story short, i replaced the speed sensor, and replaced the trans temp sensor along with the fluid and filters. it ran out fine with no load last night, put the gooseneck on this morning and the problems started up again. trans temp gauge bounces around, truck won't shift out of second gear (limp home mode i believe) and the tbc fault light flashes on and off. NO trailer brake output. are these problems related? is there a common place to look for shorts in the trans harness? any help would be greatly appreciated.
