Gearbox dipstick? Any thoughts?

[green A8]

I was having a chat to an old friend of mine who owns an engineering company, one of the few old school engineers left in the country. For a hobby he restores Spitfire fighters to airworthy condition, so you could say that he's pretty good at fixing things. He hasn't crashed a Spitfire yet, though he did his best to remove some roof tiles from my house last summer, with a very low level flypast You can't beat the sound of a Merlin at full chat!

We started chatting about cars, and somewhere in the conversation I mentioned the dreaded Audi 'sealed for life' automatic gearbox, I suggested that a lot of the issues with this transmission could be avoided if the cars owners could check the state and level of the transmission fluid, and top up the oil levels 'as required' through a simple old fashioned dipstick/filler tube. As all automatic gearbox's I've ever encountered used to have in the 'good old days'.

The end result of all this nattering is next time he's in my neck of the woods, he'll be borrowing a spare gearbox and having a go at 'fabricating something' It may not be the worlds most advanced mod ever, but I can't see why it couldn't work?

opinions and suggestions would be welcomed.
