My 02 duramax sometimes gets a dead pedal in low range. It only does it in low range. Sometimes letting off completely on the pedal and it will work normal. Sometimes the transmission won't shift out of 1st gear and then only will rev to about 2000 rpms and dead pedal. Let off the throttle, and reapply and it will shift and go fine. Any of you ever run into this? I think I have read somewhere about cutting a wire that won't tell the tcm that the transfer case is in low range. This is sometimes a pia when you need some wheel speed to get out of a spot and the only way you can do it is to shift to 4 hi. I have tried data logging and when I log it it won't mess up.
