Bought an 03 blazer used acouple months ago. Ran great til i took it out of town, once i exited the highway and stopped at the stop sign, first gear barely moved. Next time on highway, wouldnt shift into 4th gear and had same issue after exiting highway. Now car has lost reverse and will not move in "D", but will move when i shift i to 1, 2, or 3. Threw 2 codes, p1810 and p0756
