I have a f-350 diesel (97) it has a bigger turbo K&N intake and a programmer i just bought the truck and i realized it shifts very stiff like shakes the truck stiff is this good or bad?... ( i know this is a a f-150 forum but i figured you are all knowledgeable enough)

 

mine used to shift hard when i replaced the tranny like it would even make th truck move but it settled down after a while
