Calling all evil guys. Evil, your advice was good on this topic, just wondering if you can think of any other reason for what happened? I think I am going to take a litre out of the oil pan and put in a litre of tranny fluid (or another good flushing fluid??) and run it for about 20 minutes then remove it all. Shame to do it on my 5 w 50 synthetic but it was pretty thick sometimes anyway. Thinking pluged somehow on one side. Other than my screwing up I cant think of anything else.
