We got the car running again this afternoon after installing a 4 link rear suspension,The trans has a leak(have'nt found it yet) and was down on fluid after setting.There was a very loud clanking/knocking sound which sounded like it was coming from the dampner pulley, Once I added some tranny fluid the noise stopped. What would cause this? Thanks,D Last edited by bigD; 06/28/10 09:24 AM.

John,I did think of that,but the engine only has a few hundred miles on it.Seems strange it would stop when the tranny has fluid in it, but then again I've seen cranks(chevys) move forward and aft by depressing a stiff clutch with a bad thrust. Could you enlighten me a little more as to what is going on with the 727 that would make the sound(s) I described( ie converter moving in and out of the pump housing ect.)

It's worth checking the crank end play and the converter bolts. The INTERNET, the MISinformation superhighway
