I have a very big rattle in torque converter and need advise on what problem could be and how to fix it please. Cheers Charlie
-
The screws that hold the flex plate to the converter are probably loose.

How big of a job is it to fix ??

Not hard. Take the cover off at the bottom of the bell housing and turn your engine over by hand until the screw heads appear. Check to see if they're tight and turn each screw until it is. If they're tight but the flex disc is loose, it may be that the screws are too long and they're bottoming out in their respective bores. Replace the screws with slightly shorter ones or add a washer. A loose or broken flex disc will make a lot of noise.
I've also had one where the actual disc was cracked but in that case the noise was really only there at idle and it would go away at road speed. If that's the case, you will have to remove the trans to replace the flex disc.

Hey Doc,
Please confirm, 'remove the trans to replace the flex disc'. Is the flex disc not the rubber disc joining the trans to the prop shaft? Or is there another flex disc?

Very good I'll go and check cheers

This is the metal flex plate or disc between the flywheel and the torque converter.

TKS Doc,

Hi,
to clarify this discussion see following picture. I hope it is right and clear.
(drive plate = flex plate)

As a note, this is the later style torque converter, steel. The earlier ones have the same six bolt connections, but have a finned surface and are aluminum.

Charlie,
Please come back with your results, unfinished threads are very irritating.
