I know that the obvious answer to how water got into my 98 V6 manual tranny is directly related to the depth of the streams I cross but I can't remember getting that deep. I have never been deep enough to get water inside or up to the door for that matter. The oil in my transfer case is fine. The oil in my rear diff is also fine, but I had moved the breather valve up long before this problem. Has anyone had water enter in their tranny through the front transmission seal? Or through the stick shifter hole? Or am I missing something obvious. Any suggestions will help because I believe a replacement is in order and I don't want this problem again.
