Just wait until you get the truck back before you give up. Believe me....I went through the back and fourth process with Acura for 2 years until I gave up and traded the car in. I'm still bitter about that and really am pissed at Acura.
Who knows, you may find this truck perfect after the fixes are done. If that is the case, Toyota did their part to make it better and gave you a free warranty. Believe me, I would love to have that warranty for free, but I am glad I haven't had a tranny issue since I bought the truck
Try to do your best to keep your head up.
