torque converter

Is there such a thing as an out of balance torque converter??

I would of thought if bolted and spaced it corectly cannot be out of balance ??

As it's mostly fluid and the casing etc is balanced during manufacture, it sounds unlikely.

Unless there is balance weights on the outside of it that have come off.
Can be dangerous if it is out of balance. Could take the box or the crank.

That's what I thought been told to turn it on the flex plate I havevhad a rattle for two years now changed my flex plate becuse that was knackerd but its Noisy when cold . Changed oil twice now over the years including filter but it still seems to rattle when cold . No Sign of contamination still there when warm but no where near as bad clueless no slippage slight flaring when cold other than that all is well?

Very unlikely to be the torque convertor IMO.

Grit Valve · Apr 5, 2013

Well I'm clueless don't feel any untoward vibration strange.

Are you sure it's from the box or bell housing area?

Data its defently with the box no Noise what's so ever in nutral from engine it rattles just before each change more 1 2 and 3 less silence on lock up but as I say when warm say after say 10 miles it settles

When the V12 Jag engine came out, they ended up restricting the rev limit to way below the designed capability of the engine - the reason given was the specified torque converter for the (Borg Warner 35?) transmission was only balanced up to 7K rpm. So it seems torque converters do get balanced.

Loose bolts in torque converter?

Could it be a failing oil pump? Arnt they just behind the TC?

Well, the torque convertor is still rotating in neutral and if the rattle occurs on shifts I'd say either the insides of the torque convertor are falling apart or there is a problem in the box. Where's your trusty stethoscope?

Wammers defently tight if failing oil pump would that not caus slippage ?

Low oil pressure = no drive. You got enough oil in it and in the transfer box.

How can listen if it only does it whist driving I haven't got a rolling road

Oils fine no leaks always checked .

Could there be play inside the TQ ?

Centre console off, box cover off, no problem

It has previously been reported that low oil in the transfer box produces a rattle.

Have you checked the oil in the transfer box?
