Hello I'm having a problem with my tranny over heating and then I get two codes on my efilive autocal
P1711 and p0700. I have a 2001 gmc Duramax. When the transmission gets to about 180-200 degrees it goes to them codes and makes my truck go into limp mode. It starts me out in 4th gear and for some reason I don't have reverse at points! Please help when possible
