8F35 automatic: weak planetary gear set, leaks at the driveshafts

expensive

The planetary gear sets in this gearbox are weak and their service life is short: with vigorous driving the planetary set can fail after as little as 100,000 km.

Show the rest

Oil leaks along the driveshafts and through the electrical connector are common. The gearbox sometimes thumps when coming out of Park, and can even jam. The remaining complaints concern control unit glitches, which were addressed with software updates.

above 100,000 km

What to check

  • Come out of Park several times: there must be no thump and the lever must not jam
  • Accelerate briskly: the shift must not slip and there must be no thump between gears
  • Look where the driveshafts come out and at the gearbox connector: oil traces mean a leak

Information, not an expert opinion

We write the descriptions, and we put the source next to them. A person reviews them before they go out. They are still information, not a technical expert opinion.

  • A fault on the list does not mean the car you are looking at has it.
  • A fault missing from the list does not mean the model is fault-free. Write-ups are made model by model. Not all of them are done.
  • You decide whether to buy. This is no substitute for an inspection. That needs a workshop and a history check.
