My father had an old Renault (circa 1970's) that had an electronic=20 solenoid that manipulated a robotic arm to change gear. Renault called it=20 an automatic - it had a push button control panel on the dashboard. All the= =20 gears could be selected manually or the auto button pushed and it would=20 change the gears by itself. The car had no clutch pedal. I assume another solenoid arm depressed the clutch plate when required. -- cdb, colin@btech-online.co.uk on 7/08/2012 =20 Web presence: www.btech-online.co.uk =20 =20 Hosted by: www.justhost.com.au =20 =20 This email is to be considered private if addressed to a named individual= =20 or Personnel Department, and public if addressed to a blog, forum or news= =20 article. =20 =20 =20 --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
