So I got a 01 GT with the t-45. When taking off in first gear normal driving I hear a sound that's hard to describe. It's almost like the sound of fluid moving around or if you were to very faintly lug the engine a hair. Kinda jsut sounds like everything is turning. The tranny shifts like brand new with no issues at all and still on factory fluid at 54k ( need to change it). I know I am being picky but is this normal?
