MY snecros in my 91 accord are going pretty bad and i dont really know why there going so bad like if im at a high RPM in second gear like 4,500 or 5 and i put it in third it makes a bad noise like my snecros.(sorry dont know how to spell that word) anyway i have the clutch in all the way and it still makes the grinding noise and i dont no what the problem is and i dont no how to prevent it. The motors stock everythings stock on the car it has like 201,400 miles on it. But also the same thing happen in my 92 civic but it was fifth gear snecros that went bad first.but i dont know how they get bad. Can i get some help thanks.
