Change Gearbox Oil on 1.8 ZX18xer

[Paper1]

Hi, I have a 57 plate, 1.8 petrol Vectra with 1st and 2nd gears whining badly.
So I thought I would change the gearbox oil and add molyslip.

I looked at the two How Too's but they relate to the Diesal version and the area where the fill plug is (in the How Too) does not look anything like
mine.

Can anyone shed some light on this please to enable me to change the oil
?
Thanks

There are no dedicated oil holes for adding or removing oil on the F17 gearbox, who's idea was that!!!! To remove the oil need to remove the gearbox end plate and let it drain out there. You may need to buy a new gasket for it though. To add new oil im sure someone mentioned you can remove the reverse selector switch and add it in there.

Thanks for the prompt reply, I think it best I find a local gearbox specialist
and let them have a look. Cheers
