06 Mountaineer Premier, 4.6L V8, ****ty auto trans
 

Is it possible to convert the automatic trans to a manual trans from a mustang, lghtning, f series or anything of the sort because the tranny I have now sucks and the dealership i bought it from basically says too bad about the tranny even though the warranty is still good. So is it possible to swap the auto for a manual trans thats built to hold more torque?
