Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Hi all, it appears my diff has worn out. I believe due to the wrong wheels & tyres fitted between front & rear causing a 19mm tyre diameter difference. They were on the car when I bought it at 45,000 kms early this year but don't know how long on car. Is there anyone in AUS known for rebuilding Porsche Tiptronic Gearboxes & Torque Converters & Diffs? Is the diff the same as used in the manual transmission? The tiptronic in the 996 Turbo is built by MB for Porsche I believe. Maybe might be cheaper buying a complete secondhand gearbox from overseas. Problem is no warranty & don't always believe auto dismantlers claim on very low kms. Sitting on a shelf for years with low kms (claimed) probably would not be good especially for seals etc. Have spent a lot of time online with few results especially regarding overhauls. Any info would be great.

POST 2Original post

As it is an MB box there should be transmission specialists that have worked on them before. Would probably be easier, cheaper and safer to get them rebuild?
