I just put a 3550 in my hunter and the Tremec manual said no speed shifting until it gets broken in. They reccomend at least 500 miles of shifting up and down thru the gears and no speed shifting untill after 1000 miles. The only tranny fluid they roccomend is the GM syncromesch.

Is yours broken in yet???

I have read that not breaking in a tremec is bad news.
