Please help!! grinding from toploader

[priobe]

Hello All,

I am experiencing a grinding noise from my tranny when I engage it in gear. Everything was fine before I removed the trans to get to the back of the block to fix my pressure releif valve on my 427 FE.

Here is the problem:

When I start the motor and idle everything is fine. When I press the clutch I hear a grinding noise in netural. As soon as I release the clutch the noise goes away. If I try to turn off the motor and put it in gear then start the motor with the clutch pressed in, the noise is there even louder. I have tried releasing the clutch while making the noise and the car moves without the grinding noise. The noise is intermittent.

Here is my setup:

Centerforce flywheel
Brass pilot bearing
Centerforce clutch
Centerforce pressure Plate
Lakewood Bellhousing
Top Loader Trans
Tilton Hydraulic Release Bearing

I verified through the fork hole in the side of the bell housing that the release bearing moves about 3/4 to 1 in. travel. I have also bled the system several times.

Can someone shed some light before I pull the tranny.

Please help
