This just happened very suddenly while accelating uphill in 2nd gear. Very loud gear grinding noise but was not shifting and tranny stayed in gear. Sound continued after shifting into 3dr gear. Got car into garage sounded like it was coming from valve side of engine. Ran rpm's up to 1500 or so and then soud went completely away! Idled at 1200 rpm's for 15 minutes, no problem. Drove up driveway and it happened again, put in clutch reved engine and sound went away. This is a mystery to me.
Thanks
