Vibration

[_dOp_skyLINe]

i have a weird vibration from the car, when i am in neutral and rev to about i hear a hard vibration and when i check under the hood its vibration with some sort of knocking coming from the tranny, then once i press the clutch in neutral the vibration completly stops or when i rev when i am in gear with the clutch in nothing happens either, only when i rev in neutral vibrate. When i drive normal there is no vibration, the vibration comes when i release the clutch fast, , then i have to engage the clutch and release slow and no more vibrations

sorry for my bad english i hope all can understand, thank you to all.

might be bad motor mounts. Its hard to distinguish a vibration when not heard in person.

It sounds like your throw out bearing might be broken. Sadly, the only way I know how to check that is to drop the tranny.

motor mounts are new, i think is the throw out bearing to but i will drop the tranny.

Usually the throw out bearing will make noise when the clutch is depressed, not when it is released. When you depress the clutch with the car in neutral all the internal gears stop turning and when you release the clutch everything inside starts spinning, so that tells me you have something wrong inside the transmission. A lot of the time it is the input shaft bearings, but not always. It could actually be one of the following:

1st, 2nd, 3rd, 4th or 5th gear needle bearings.
Old blocker rings are known to 'rattle' at idle, specially 5th and reverse.
Input shaft tapered roller bearings.
Bad rev gear synchro blocker wave spring.
Loose shaft nut.
Loose or broken clutch disk hub.

Sounds like you might have to go inside the tranny.
Good luck
