I have a '71 C-10 Deluxe and I replaced the steering column with a manual 3 speed today. Here is my dilemma. In the yard sitting still, you can change the gears ok. When you start out on the road, it hangs between 1-2 gear. You are stuck in 1st gear until you get out and move it under the hood. Please help. I am scraping the bottom of my bucket. Thank you!
