SMG issue in London

[abbottti]

I have a 2002 M3. The gearbox light on the dashboard came on today just a mile after leaving home. It jumped into 2nd gear with a jolt and then on slowing down it wouldn't go into 1st without first going into neutral and back into 1st again. The car seemed fine yesterday when it was last driven. A very sudden error. Can anyone suggest a good independent garage to contact in London for them to take a look (I live in SW London) ? I found these guys on the web http://www.technosport.co.uk/mpower.html but I would prefer a recommendation.
