so today i was driving home and i noticed at dead stops something was rattling. making weird ugly noise. so i listened for a while and thought it was my engine. but i drove a bit and noticed it was only when i was taking off in first and then shifting to second. then twice it wouldnt let me shift at all! had to turn the truck off and then put it in gear. i already have a clutch but would like to know what the heck is going? i just got home but im going to take a look at it myself tonight.
