It just happend today when you shift from 1 to 2 it will grinde not all of the time but most of it!! And it really sucks,if you pull up to a stop light and try to put it into 2nd it will do it,some times if you double clutch it wont or really push hard on the clutch pedal. I just put a clutch in it about 1200 miles ago and have not had any problems even put a new slave cylinder on too. It all still seems to be the same as it always has been.. I also put a quart of lucas in the tranny and new gear oil in it too...Thanks for any help it is a 98 4x4 with the 5 speed
