okay so i am looking for a solution. here is the problem, when i rev my car in general, (neutral/gear/standstill/driving) up passed 5.5k RPM's i get some low tone sound (like something is going to come off in the engine or tranny) and extreme vibration up the shifter. this only happens at high rpm and is normal anywhere below that. here are some things i have already considered: broken motor mounts?, broken tranny mounts?, out of balance flywheel? (i dont need to have the clutch engaged for this problem), driveshaft/u-joints? (vibration happens even when car is not moving), diff?, or broken/loose bearing in the tranny? (but tranny seems to be working fine with no grinds and is smooth).

I would like to ask if anyone has experienced this before and what is the problem and how you fixed it. Any useful information is appreciated. i am not a expert and am looking for expert answers because i keep getting shot around by shops that it could be this/that and charging me an arm and a leg to find the problem. thanks

 

if you can take off the trans and try it.. if its still vibrating well you know were to look

 

you can also try slowly jacking up the motor to see if one of the mounts is broken. i had a broken mount and my **** was shaking pretty bad.

 

cool ill start and have a look at the mounts before anything else

 

Problem solved. Loose fan

 

I had that exact same thing happen to me.^Shame I wasn't on here earlier, I could have been helpful. Oh well.

 

He did have two years to figure it out.
