Greetings, new to forum. I just bought a 2000 4x4 blazer with auto trans, and it does not go into low gear when starting out in "D", 3, or 2. it will go to low when placed in low and will shift up to each gear when done manually. It seems to be in which ever gear it is placed in. Do not know if it matters but ABS light is always on. I tried seaching but did not find these exact problems. Any help would be great.
