About a year ago I had ABS lights come on with a C0055 and I lost my speedo, brakes felt fine, truck ran great so I ignored it. About a week ago on my way to work I had some rough shifts from 1-2 and down from 2-1 then all shifts up and down randomly. You never know when you're gonna have a hard shift. Replaced the speed sensor and still have the same problem.
