Hole in Gearbox?

Hi,

I am new to this forum so forgive me if this has already been covered.

I have owned my MK1 Cabrio for nearly 4 months now and I have had nothing but trouble with my gearbox. The week after I bought it the fifth gear nakered up, so I had to spend ?250 on re-conditioning it. Found out there was no oil in it!

Even though the box has been re-conditioned there still seems to be a whining noise in 5th gear.

I believe this is due to lack of oil again, but I seem to be having a problem with filling the gearbox up with 2 litres of oil. I seem to fill it to about 1 litre and oil starts to pour from this hole at the bottom of the gearbox (pic below), Does anyone know what this hole is for? I have had to plug this in to allow me to put the 2 litres in, but i'm not sure this is suppose to be plugged?

For info my gearbox has FD21012 stamped on it.

Any ideas?

Regards

Mike.

How do you know how much oil is already in it?

TT

I have dropped the oil several times and attempted to fill with the specified 2 litres, but seems to pour from this hole after about 1 litre of oil has been put in?

Mine has a bolt there. And i think its somthing to do with reverse gear.

Hope it helps

Thanks for that info i'll have to investigate further……….

there should be no holes in the gearbox that arent pluged by something  8O

I spoke to VW today and they said there should be a M8 x 28mm bolt that goes in there to secure the reverse gear spindle.

I have just been out and tried an M8 bolt in there, but there doesnt seem to be any thread to screw into??

I suppose my reverse gear works fine so I might just plug it in?

thanks for your replys,

Mike.
