Make sure you know how the motor blew.  If it overheated and then blew up
(which is mostly the case) then the autotranny, since it uses the engine
coolant to cool the tranny oil, will have most probably have suffered from the
engine overheat as well.  Here is the usual scenerios.  Engine overheats and
fries.  New engine put in, tranny goes bad shortly thereafter.  Anyone else
have this experience?
