I have a Dec 2000 A160 automatic. If it were a manual I would decribe the problem as a slipping clutch.Upon pulling away from a stanstill the engine revs but doesn't want to engage gear. If you rev it too hard an "F" appears on the dashboard display instead of the "D" and I loose all power. It can only be rectified by switching off the ignition and restarting, which isn't always possible in the middle of a junction.If you pull away slowly it will eventually engage gear at about 4000 revs and once first is engaged off it goes fine. Any ideas please?
your car is on limp home mode. it is a feature of your car to ensure safe driving and preventing further damage if the FTC has detected a fault. it is possible to shift on 2nd and R just to drive you way home or to the nearest garage. switching off/ on the ignition could temporarily fix it. first thing to do with this problem is to check the ATF level. IF level is okay, have your car scanned by HHT diagnostic tool to be certain whats causing the problem. it could be the shift valve, regulating valve or worse the electrohydraulic control unit.
