I just recently Installed a extended shifter now my truck is stuck in High range. All I did is cut 6 wires that’s on the shifter and extended them.
How did you cut those airlines?? If you used a pair of wire cutters, that is your problem. They need to be cut with a razor blade in a circular motion so you dont crimp the air line like you would with cutters. If thats not the problem, you absolutely installed the wrong air line in the wrong port. 6 air lines is gonna be a tough one. Why so many for that truck. I have 3 lines for my 18spd
Ok. Never saw one of those. So still the same thing. ITs an error you made splicing the wires or connecting them where they supposed to be. Sorry to say but is what it is. in a situation like that, i always take pictures of where everything is at before dissaembly. Did you do that i hope?
