You have no idea how many trannies have gone out. You are just guessing like the rest of us. Why don't you call Toyota and ask them? Because they are guessing too. They still haven't publicly addressed this problem like the camshaft mishap. They are in the "head scratching" phase of this, and hopefully they will shed some light soon, so we can all take a deep breath and keep enjoying our trucks.
