Automatic gearbox top up (Unable to find a dipstick like most other auto boxes) We Need to top up the box !!!!!
We have a light come on the Dashboard normally E or D but now when hot E &D go out and in between orange lamp comes on with what looks like a Cog with a ! mark and ideas.
Never worked on one, but Autodata CD tells me that there is a drain plug on the bottom of the gearbox. Follow the join in the casing around to the side from this - nearside if I read the illustration right, and on the opposite side of the join (ie to the rear), and you should find another similar-sized plug at 90 degrees to the drain plug - this is the filler plug. I've emailed you a picture. Where no dipstick is provided the usual technique is to fill to the level of the drain plug, although I make no promises for a BMW!
If you feel like completely draining and refilling the transmission, which is an item on the major service schedule anyway, it takes 3 litres of Dexron II ATF.
This reminded me of something that one of the butchers in my local Tesco told me recently: his weighing scales went wrong a couple of weeks ago and the cure was.....a new hard drive!
By "mainstream" I was really meaning cars of an age that they would be more likely to be owner-maintained. This really will be a problem in the future.
