Symptoms
Judder, flare or harsh shifts, an unknown service history, or a weeping valve body sleeve.
The fix, step by step
- The filter is built into the plastic pan, so you replace the pan.
- Drain, drop the pan, and replace the valve body sleeve (a common leak point) while it's open.
- Refill with ZF-spec fluid and follow the factory fill-and-level procedure with the fluid at the specified temperature.
- Workshop data quotes 9.5 litres for a dry fill; a pan change takes far less, so some owners repeat it to refresh more of the fluid.
Tools & part numbers
