My nbs Sierra came with a factory kill switch key that worked perfectly well the first year I had the truck. But after that year it stopped working.I was wondering if anybody knows how to reactivate it without haveing to pay gmc a yearly price.
4l60e is giving out harsh takeoff sometimes jumps into gear, lo-reverse and slipping in gear shift between 1-2 I hear the 4l70-80 are way better trannys
Anybody out there swapped their stock 4l60e for a newer 4l70e or 4l80e is it even possible and is their a significant performance increase with the 4.8 v8
Off topic but anybody know how to the drl to flash with the turn signals . I have everything led even interior except for the rear brake and turn signals. I changed the stock flasher relay to a led compatible one as well. I tried to hook up the del wires to the turn signal wires but that didn't...
