Have got so fed up with VW garages I have changed my vento auto fluid by syphoning out and replacing about 3 litres of atf. I didn\'t change the filter.How important is an auto gearbox filter ?

They have filters? More to the point, you siphoned it?
Is there not a drain plug on the transmission for your car?
Why am I responding to this instead of moving it to "Technical"?

Is there a drain plug on any transmissions. I think very few cars have them. Most of them you have to whip the sump off. (Sorry to hyjack the thread.)

It varies. Some have drain plugs, some don't ('filled for life').
I think your Vento has the JATCO 'box. Make sure you've used the right fluid. It holds 8+ litres so you've not changed much of it.
Personally I would take it to an auto-trans specialist and let them do the change if you're not sure what you're doing. Get a but of muck in one of those (or put the wrong fluid in) and you're looking at c.£4k for a new 'box.

On most auto boxes, even if you can drain the box, you usually can't drain the torque converter, and that holds a significant proportion of the total fluid content of the unit.

Two ways round that. You either do repeated drain-fill-drive-drain-fill-drive, three or four times. That changes most of it. It you can get ATF at bulk trade prices its not much of a problem. This is what I do.
Alternatively, disconnect cooler pipe and run engine at tick-over whilst refilling 'box. Do it until clean fluid comes out of cooler pipe. Switch off engine and top up.
