(Clutch or Tranny problem) Shake & Rattle 79'z28 w/SuperT10 ! (Video)

Hi guys we have a problem we are trying to isolate for a couple of days, we have this 79' Z28 with a BW SuperT10 tranny,all rebuilt,new clutch kit pressure plate and disc. coupled to a 355.

This is really annoying,when we clutch from 1st to 2nd on load , the car shakes like a madman !

We swapped the pressure plate for another one, same problem ! If you are careful while clutching you can avoid the shaking,its on certain spot that this happens ...

We were told the clutch disc needs to get used to it because its brand new , new fork,new bearing and mount as well.

I dont think the disc will cause that of a chatter ! It's too much !!! the whole front end shakes ! (specially if you are clutch going uphill) and i can hear a metallic sound near the bellhousing area.

It's too much,we got the flywheel on dial and its correct,its not bent or something ...

Today we decided to record this video because it's getting real bad.
Any ideas ? Thanks !

You sure you don't have teeth missing from the ring gear or the spiders? Is the flywheel and pressure plate tight?

Sounds like a problem I was just having myself. Things I found that could cause this problem. Did you change the flywheel? May be out of balance. Check the two pins on the back of the motor that alien the bell housing. If they are not out enough the transmission can twist and be really hard on the pilot bearing.

I'm having a smiliar problem, but still havn't figured it out. But here's some things to check:

Check your tranny and engine mounts. Make sure their bolts are tight and the rubber isn't cracked or really soft from oil.

Also check driveshaft u-joints.

Make sure slave cylinder is tightly bolted on.

A leaking rear crank seal can also cause the problem, but hopefully that's not it.

Check transmission to bellhousing bolts and bellhousing bolts to engine block too.

Tranny mount is brand new,i will double check engine mounts.
U joints are old ones,i will swap them.
Transmission bolts are tight,i took it off last week to check swap pressure plate and see if that was the problem,it was not the pressure plate.


i have some small oil leak ..coming from the spot circled in which i think its strange !
what you think ? thanks !

Clutch chatter is from either flywheel or the clutch disc. Clutch discs need to break in but shouldn't chatter like that new. I'd say you have to pull it apart and have a look at the friction surfaces. What kind of clutch are you using?

I've had broken motor mounts allow the motor to torque up and the fan hit the shroud. Sounds similar but no real shaking to that. If it's happeng it,
it could be twisting things. Do you see any wear marks around the inside of the bellhousing or on the ring gear teeth?

The oil leak is very strange, I've never seen the pivot ball hole extend clear into the oil passage, all my vehicles with auto trans' just have the hole open, are there any cracks around it?
