2000 S80 Transmission filter post mortem

Hello,

I recently bought a 2000 S80 T6 (188k Kms) and I've just replaced the trans filter.

Thought I'd look inside the old filter - wishing perhaps I hadn't.

Does anyone know what the black flaky stuff would be? It's not metallic, but there's quite a lot of it and it's up to about 2-3mm in size. The transmission shifts fine when cold but starts misbehaving a bit when warmed up (flared shifts 2-3 and then a hard shift unless I back off the gas).

Ultimately I knew I'd be up for a transmission rebuild, but hoped it would last a bit longer...

Cheers,

Chris

sounds like a possible clutch on the way out and looks like clutch material.

Thanks for the reply...

<thinking out loud> Hmm, has anyone rebuilt one of these Volvo gearboxes (4T65E-GT)??

There are plenty of people who've rebuilt the more common GM 4T65E auto boxes on other various car forums, and the parts are readily available and they can be uprated to handle a modest power increase and fix the bugs.

Shame there's no LSD from what I can see that will fit in the transmission.</thinking out loud>

Cheers,

Chris

There are no differences in rebuilding the GM and Volvo versions. Geartronic is only a decoupling shifter (lever pulls over into the upshift/downshift gate where shift cable to trans isn't moving) with lever motion sensors and software in trans control module.
I do agree that that is clutch lining pieces.
Your 2000 T6 may have the external LSD. If the RH driveshaft has a cylindrical housing on it that is the viscous coupling that dampens L to R speed differences.
