I recently replaced tranny & clutch. After all the work was done I noticed some vibration in low RPM area but when reving up to 3K then the vibration is terrible. At first I thought that the tranny is bad but vibration stays also when clutch is pressed.
Can anybody hel me?

thnx.

It could be that the rubber bushings on the transmissions mounts are bad, those sometimes can cause vibrations if they are bad.

 

I checed them. 2 of them on sides were ok but the middle one was bad & I made some modification to it. I pud a rubber hose around the metal part of the bushing and pressed it in. Mabye it's to tight now?

Did you pull the flywheel when you did the clutch? Are you sure the clutch was installed properly? Driveshaft? Does it happen when the car is standing still?

 

Flywheel stayed on while i did the clutch & driveshaft is aligned. And yes it vibrates all the time Driving, standing,clutch on & off.

I'm confused.

 

I installed a new clutch a couple years ago and had the same problem. I found out the new clutch was out of balance, WHAT LUCK! My parts dealer replaced the clutch , but I had to reinstall it. Hope this helps

 

If it vibrates when standing still then it has nothing to do with the driveshaft. It has to be in the clutch plate itself. If it didn't vibrate b4 and now it does, then it has to be something you changed. I don't believe it's the tranny, I'd check the disc and PP.
