^^^uh ohh. could be oil consumption, get that checked out asap and make sure your oil is at the proper level. otherwise BOOM. you might need to do some work. about the same price as a clutch possibly just to fix it.

 

I have the JWT clutch/flywheel combo i bought it for $775 shipped here

i had my transmission shop install the parts for $300 so $250 is a good deal

you will notice more flywheel chatter when you are stopped and going up hill, you just have to get used to the noise
