Hi, When I am changing gear or sometimes when I am in gear if I press the throttle too hard all I get is lots of revs. I need to be gentle on the throttle in order for the gears to engage. 3rd gear is also a little stiff, are these problems connected i.e. is my gearbox or something related on it's way out? Thanks

 

Whats the mileage. Have you been changing the gearbox oil as per spec. Some people do not realise that the gearbox oil has to be changed. Most manufacturers fit gearbox oil for "life".

 

Hi change the gearbox filter and gasket which is less than £20 on flee bay and change your transmissions fluid atf+4 I had this on a old 98 3.3 and its been sweet since make sure you put atf+4 as ordinary atf is not correct for the voyager regards Paul

 

Think the OP was looking for help with a manual box, not auto.

 

If its a manual gearbox then is probably 99% clutch slip.
Either worn friction plate or damaged pressure plate.
