1999 310 Sundancer. Vdrive oil was just changed. Only got two quarts back in as the vacuum sucker couldn't get it all out. It looks like the transmission fluid is up about one inch on the stick cold. Now after even 5 minutes or so of running boat on plane, trans fluid blows out the vent. I'm thinking it may be over full, but could leaking coolers do this also? In the last week or so the port shifter has become very difficult , like binding into forward and reverse since the oil was changed. I have disconnected the shift cable and it definitely seems like the linkage inside the transmission. Anyone have anything like this happened to them? Also, when it sat overnite, I could hear a "hissing" when loosening/removing the transmission dipstick, I don't think the vent is blocked as it blows fluid out underpower.
