    Default How to stop upshift from 1st to 2nd while in 1st gear 2003 silverado 4L60

    Hey guys is there a way to keep my truck from shift out of first while my gear selector is in the first gear location? I was goofing around today and had my tires covered in mud so I pulled out on the hard surface and pulled it to 1st on the selector and held the brake and hammered down, haha. Even though I was in first it still upshifted to 2nd gear while the gear selector was still in 1st gear. It won't hold low gear. I thought I had it set to hold first gear but I must of missed something.
