i recently had the tranny flushed and then i took it off road where i boiled the tranny over. i let it sit till it cooled and then drove home. it didn't shift or act funny. i've since parked it to rebuild the rear end and change gearing. is there anything i need to do? should i flush the tranny again? i know i'm on borrowed time with this thing and i really don't want it to shit the bed while i'm in BFE.
