Vectra Cdti transmission oil??

**mossy2432** · 21st May 2011, 15:38

I'm doing a oil change on my gearbox and I'm just wondering how much oil should drain out as I've drained out 5L out of mine is this right as it states in the manual 2.2L should go back in... 1.9cdti 6speed box

Any help with this matter would be appreciated thanks all :-)

the recomendation on this site mate is to put 2.2 back in,,i put 2.5 back into mine,,,but i used cheap grade gearbox oil and to be honest i should have got quality stuff as when my gearbox is cold,,,the gear change notchy between 1st and second,,,but once warm its very smooth,,i also drained around 4.5 to 5 litres from mine

well 1st to 2nd on mine rubs a bit,,and also 2nd to 3rd a small bit when cold... but when warm its fine,,i used a semi synth gearbox oil,,,it was a cheap brand,,i guess with quality brands u get smoother changes,,, i tend to try and slip my car into gear anyways when i drive rather than push it,if u know what i mean..
