I have a 1995 c2500 2wd extended cab with a 6.5TD and a NV4500 trans. I replaced the dual mass flywheel and transmission about 6,000 miles ago due to hard shifting when the pilot bushing let go.
When I replaced the flywheel I up graded the Transmission to a 2000 nv4500 w/ dampner and a 2000 bell housing and throwout bearing.
Now the problem. When I push in the clutch pedal I get a heavy vibration in the pedal along with a loud roar. I replaced the new throwout bearing and found it to be all wobblly. Not nice and tight like it had started life 3000 miles earlyer. When I replaced the factoy throwout bearing I retorqued the flywheel and also found no wear on the bronze pilot bushing. I am about to replace another throwout bearing because the pedal vibration is getting bad.
Any one have any good ideals what the problem is?
Thanking you in advance.
