Everytime I come down from third gear, whether my foot is on the brake or not, my car jerks and makes a pound noise. I believe I've heard it called a "downshift bump" but I don't know about it. My car shifts upward smoothly into every gear. The only problem is downshifting from third into second right around 25-29mph. Any idea what it may be and how much it may cost to repair?
