Havent really seen many of those computers fail how do you know its bad?Before you rebuilt the transmission did you do a pressure test on the transmission using a tech2 scan tool to command the line pressure solenoid to the different currents while watching the pressures?Thats really inportant that you do that beacuse if you doint make sure the pressure is good before rebuilding it you could ruin the belt pulleys etc.I have seen valve bodies and the transmission pumps go bad on those causing the belts pulleys etc to fail. Also why did you rebuild it what were the symptoms codes etc?I have rebuilt a lot of those transmissions iam factory trained on those. Also when you rebuilt it it what did you replace?Did you replace the transmission cooler lines and flush the transmission cooler?If not thats a must when rebuilding them also you must replace the internal filter while rebuilding them.
