Transmission in limp mode
Yesterday my speedometer and tachometer stopped working and right after my transmission went into limp mode with codes P0753 P0758 P0785 P0740 P1860, basically all saying loss of electrical connection. It won’t shift in drive but I can shift between second and third. All fuses tested good but I noticed the ground from the firewall to the frame then back up to the passenger rear side of the motor are both broken. I suspect that may be the problem. Any ideas? 1998 C1500 5.7 4L60E
