10 speed is a great transmission. The suit is more focused on rough shifts than actual failures. Ford has explained this is due to the learning process. I can attest its not a big deal. I have the 10 spd in my 1000hp GT, its a super tough transmission. I beat the hell out of it in my Mustang. Also have it in my F150, no issues. The transmission learns pretty quick how you drive, it skips gears to save gas under light throttle. From my experience I say you'll love it. If you worried, look up the class action suit. There are several million of these on the road, it's in Chevys, Mustangs, F150 and Camaros. Percentage wise low failure rate.
