New to the forum here and was wondering if anyone can advise why my tranny is slipping at wot from 2-3 gear. In first it shutters at WOT (1-2) at cool temps but when warmed up it will slip if I get on it, only from 2-3. If I drive normal it will go in every gear smoothly; Except on a hot day when I'm sitting in traffic then it will start jumping in every gear until I shut it off for a while. Also my transmission fluid is burnt(Brown in color) and its only been 15000 miles since I changed it. I've already added 2 bottles of Lucas during the 15k miles(to help with slippage) and its already burnt. Any advice would be greatly appreciated. Oh yeah and when I bought the car it had 140k miles. It now has 155k
