Well they both were good. But in the trucks I drove I felt the Ford was smoother. Especially when downshifting. Seemed anytime there was a downshift of 2 or more gears the Ford handled it much better. The GM seemed to hunt through the gears more where the Ford felt like it found the right gear more efficiently. Now this could be because of the learning period for the GM. I don't know.How was the Tranny's? Which felt smoother?
