My only advise on rebuilding the AOD is to not cheap out in the valve body department. Along with many other problems, AOD's are famous for for 3-4 shudder when warm, soggy shifts, and binding between 4 & 3 during downshift. This can cause the 3-4 input shaft (skinny one in the middle) to lock up in the torque converter and either strip the splines off the shaft, or in the converter. Soggy shifts fry clutches, and especially the O-D band. Spend your money on a decent recalibration kit for the valve body, not like the usual shift kit this will in escense recalibrate your AOD to work 100% better than new and last for years longer. TransCo sells a kit like this that I'm sure you will be pleased with.
