Just to advise that I took my 2006 Yaris diesel to the local dealer at 85,000 miles with a slipping clutch to find out how expensive it would be to repair (none of the clutch specialist would touch it because of mmt autobox) Extremely pleasantly surprised to be told they would replace the clutch and actuator for free because Toyota had just issued a recall due to some problem with the existing ecu which presumably causes the clutch to fail early. the ecu was upgraded at the same time.
