Hi I'm pete own a 1999 p38.2.5 auto love the car but she when it gets hot it get really sluggish to the point why I can have my foot flat to the floor and it will take a good 2-3 mins to move In reverse but when it's cold it's fine I guessing it need a gearbox service, but it also has a slight chatting noise when cold in reverse and drive only but more noticeable (louader) when hot I have removed the inspection cover underneath and saw the previous own had welded the flex plate my my concer is the start ring as wear marks on it from the bell housing could this be lose bolts and allowing movement and letting t/c slip any ideas would be greatly appreciated thanks
