Also having an issue with the gearbox, was very intermittent but getting more regular. When I start car in the morning, select reverse or drive, when I pull away it seems to need to rev very highly to get car to move. Almost like clutch slipping. However if I select park/neutral then go back to the selected gear everything is fine. Car has 60k, 66 plate. Have recently had gearbox oil and filters changed (5k ago). Any ideas ? Thanks in advance

Just a bump on this in case anyone has any ideas

That's normal. From cold, the vehicle will hold onto the lower gears for longer. This is purposely to raise the temperature in a shorter amount of time. Kev

If it didn’t do it before the oil change then it could be worth checking if the fluid level is correct, it’s easy to under fill it. Did it get the correct ZF fluid or a cheap alternative?
