Level Ten trannys don't come with more than a 90 day warranty.
If you are looking for a transmission that you are going to put a LOT of miles on, you need a good warranty.
If you want a tranny that is going to take a beating all the time, then go with Level Ten.
If this tranny fails anytime soon, my next one will be a Level Ten,
just to see if they can't screw it up any worse than Ford has...
