BTW, most local places that "rebuild" transmissions just replace the friction material, any broken parts they find, and gaskets. Unless you specifically ask for electronic pieces to be replaced (typically what causes failure in the first place on these transmissions), they'll leave the original ones there. Also, 90% of the time they re-use your torque converter, sometimes without even inspecting it. So, if you add in the cost of at least 4 $50 electronic pieces, a $300+ torque converter, and probably another few hundred in parts that should be replaced, you might as well have bought one from the guy that knows how to properly rebuild a 4T65E and not worry about something stupid failing.
