00 1.8 Notchy gear change when hot - longsuffering
We have started noticing very imprecise and notchy gear changes (throughout the ratios) on longer drives once the car is really hot - generally when exiting a motorway and changing down it can feel as though the selector mechanism is disengaged. Once the car cools even a little we get a usable but still notchy change.

The car was due a new clutch (or so we thought) and the garage warned us we'd probably need a new flywheel too. Both were fitted and made a 10% improvement but the basic problem remains.

Gearbox oil? I'm getting them to check it but it should have been changed when they did the clutch, right?? They charged me for the oil anyway!

Any other ideas or similar problems?

Thanks

Gearbox oil would have been my first suggestion, is the box extra noisy when the problem occurs?

As you don't have to change the gearbox oil when the clutch is changed, they may have skimped on that or used the wrong oil? New oil might help, has it done a high mixed driving mileage, if so it might be the synchro rings worn. Does double de clutching ( my, i'm getting old) help reduce the Notchy gear change when changing down?

When it's next hot try pressing the clutch pedal down and wait about 60 seconds then try and put it in 1st gear, keeping it pressed down wait another 30 seconds.....what happens.

No extra noise noticeable.
It's low mileage for its age - 65k in 9 years - quite a bit of that short journeys.
I'll have to google double de-clutching!

Thanks for your ideas
