Just recently put in the act 6 puck clutch. Drove it all day yesterday with no problems. Go out today to drive it and shift into 3rd, get about 3 grand into it, then a loud n harsh clunk noise comes from under my car. So i pull over see if anything is leaking, and there isnt. So drive again and it keeps clunking and shaking.....anyone know what this could be?!?!?

 

Please first check your tires are torqued. Wolfsfang had someone do his clutch and they left the tire loose.

 

Also check all your motor/transmission mounts
