Starting at <5k miles the vehicle power train clunked when shifting from 2nd to 3rd gear. Now at 70k miles it clunks when shifting between all gears except final drive. The dealership replaced the output shaft on the tranny, then the u-joints, and modified the electrical shift patern. It still clunks.
