i just installed my motor with a new clutch, pressure plate and flywheel. its a new motor but my original tranny. my old motor never did this only the new setup i have.

as soon as i start the car the tranny is making a realy loud grinding noise. it only stops when i engage the clutch to the floor. if i put the car in gear n leave the clutch pedal to the floor it still goes away. it only comes back when i let go of the clutch, in neutral or any gear?

wat is the problem? bad input shaft bearing? or a bad throwout bearing? please help me out, and is driving around with this noise bad for my motor? i have 360 miles on it and dont want to mess anything up. thanks

sounds like the throw out bearing is touching the pressure plate fingers......did you bleed the clutch master cylinder after the new clutch was installed.....?

maybe the throw out bearing is no good.....?

no i didnt bleed the clutch...could that fix it? i read other threads on a similar problem and everyone said its the input shaft bearing.

flush the trans fluid twice.
noise will eventually go away.
it happen to me like a yr ago.(tranny still good)

it does sound like the input shaft although check your motor mounts and tranny mounts and make sure everything is good there I would say its probly not your fluid if the noise goes away then chances are you just wore whatever gears were grinding down just enough so that they don't grind anymore
check your clutch pedal adjustment it might be out of adjustment

It's 100% your throw-out bearing. I promise you that's what it is.

i did install a new clutch n when i step on the pedal it moves alot like its loose n then it grabs...it has a little play like if i were to tap it wit my had it would go down and then up. maybe ill try flushing it.

how loud is this grinding noise?...sometimes when clutch is not engage and your car is in nutral the gears in the tranny still move. and might just be the parts moving. unless it's hella noticably loud then i'd take another look at it.

na its realy loud lol. but once u step on the clutch its gone.

well mine did this also. i changed the clutch, throw-out bearing, and flywheel. noise was still there. flushed trans, still noisey. changed trans, no more noise. i dont know what caused it but i know what it wasnt...
