Wonder if that is nature of 2010 8R series. Mine speeds up completely and then several minutes later slows all the way down and keeps doing regardless if engine is cool or hot. I wonder what tells it to do that and if it can be changed. Our 2012 8R series does not do that. It only speeds up on temp rise.
