I added one bottle of Lucas Transmission Fix and immediately the problem was GONE!!
My 2004 Dodge Dakota 3.7 automatic was slipping and jerking 35-40 miles mph feel like I was running over the pay attention ribs cut into the edge of the blacktop. Anything above or below the 35-40 mph was fine. I added one bottle of Lucas Transmission Fix and immediately the problem was GONE!! I was a little concerned because it came out of the jug like honey “thick” but it did the trick. Thank You LUCAS OIL!!! You got yourself a lifetime member!!
