Shaking when releasing clutch

At a complete stop I release the clutch and the whole trcuk shakes. It Doesnt happen all the time. just only to 1st gear no other gears are affected. its starting to piss me off. The truck has a brand new clutch in it and the flywheel was resurfaced. Any help will be helpful

All the bolts holding tranny in tight?Did u replace the throw-out bearing as well?DID U REPLACE THE TRANNY MOUNT?cHECK FOR BROKEN MOTOR MOUNT.BJ

Correct pinion angle? What about your carrier bearing, is it any good?

its a bad clutch, i had the same problem years ago, and i was delivering pizzas at the time, it got annoying fast

i am gonna bring it to a shop this week and see what it is , it didnt do it today weird shit.....

did you replace the pilot bearing??

mine does it too, only if my truck hasn't warmed up before i drive it
