gearbox oil

[62car]

hi - I'm new to the forum so bear with me! I have a zetec 1.2 to teach my kids to drive in. There's a slight whine and rumble from the gearbox. Goes away when you push the clutch in so probably gearbox bearing and not thrust bearing. I'd like to check the gearbox oil level and perhas put some molyslip in to quiten it down. As this is a 'sealed for life' unit, how do i do this? Many thanks.

I would guess your release bearing is making the noise.

There is no dipstick on the gearboxes so you cant really check the level.

What you can do tho is take out the fill plug and put gearbox oil in till it starts to overflow back out. Its a bit messy.

The plug should be at the front of the gearbox about half way up. Easiest to see from underneath
