The popping out of gear problem is common on T-10s. You need to get the Torque-Lok sliders when you tear the transmission apart. These have special grooves in them in order to prevent the transmission from pooping out of gear. I think they are about $40 a piece. I know this guy out in Philadelphia that will rebuild my T-10, install the Torque-Lok sliders for $425 labor included. That is assuming nothing else major has to be replaced, of course.
