Automatic Gearboxes & White Smoke

If you go to  my ‘White Smoke’ post you will see the problem I have had. I think I am close to resolving it - an engineer friend is going to give me a hand to replace the vacuum modulator valve. I’ve got some good photographs from an American web site thanks to Martin Young but would really like to have an exploded drawing of the gearbox before we start. It’s a 1990 Roadster Automatic. Can anyone help please? If you’ve got something that you are prepared to lend to me, I would be more than happy to pay all postal costs and make a donation to a charity as a ‘thank you’.

Having given this a bit of thought - it would obviously be better if you contacted me before sending anything as I might end up with 20 lots of postages to pay and donations to make!!

The engine section contains stuff about the auto gearbox

Thanks again Geoff !
