Can someone with EPC just check that part no 9120541 is gearbox oil for an F20 please.

Also the gearbox filler plug is th ebulky looking plug thing on top of the transmission almost directly under the ABS unit? Just want to double check.

Ed here despite screen name.

Right job done, just one thing I'm not too sure on. Haynes say to refill the gearbox with 1.8 litres, while Halfords guide suggests 1.9l for my car. Anywya I've put 1.8L in considering some of the original oil may still be left in the box.

How much do you F20 boys put in your box?

Right I've put in 1.9L of gearbox oil, and checked the level. However, Haynes manual says to check the gearbox level while the car is level, but how am I meant to check the oil level without lifting the front of the car and therefore causing it to not be level.


With the front of the car lifted more oil flows to where the level check plug is, therefore giving an over reading. It gushes out of the check plug like this.

Short of getting the car on 4 axle stands, or hydraulic lift, how should I take a correct reading?

Apparently Vauxhall will not sell to the public the oil needed to fill my gearbox, however they sold it to me.

Now I'm wondering whether they sold me the right stuff?

Can someone with EPC just check this part number for me please: 9120541

Oh yeah it has improved. TBH there was never a problem with the original oil, just after 100,000 miles I thought it could do with a change. I have noticed cold gear changes are less knotchy now, and hopefully the reluctantness to go into second and third gear on the 1/4 mile strip should be erraditcated.
