I had the throttle do this, and nearly kill me when it did it with a city bus cutting in front of me!? I removed and cleaned the throttle body (write up in the V8 wiki) and also cleaned and lubed the throttle assembly at the rear of the engine.? It really took about an hour, but I was really cautious so it took more like 2.? I'd suggest you do that before you think transmission replacement since it will cost you all of 1 can of PB Blaster and an hour or so.? All was fine after that.

Try that :)

Good luck!

I'll give you some more thoughts...    The V8 automatic transmission is problematic.  There is a seal inside  that, when it starts to fail, (I may not get this exactly right, but  I think the general idea is correct) lets engine oil seep into the  transmission. This causes a mechanical failure in the transmission  that means it must be rebuilt (difficult) or replaced (expensive).    Some owners periodically (yearly, every 30K miles) flush the fluid  from the transmission -- out with the bad, in with the good. But this  must be done *before* problems arise.  It may not hurt to have someone  flush your transmission fluid. No guarantees it will fix the problem,  but for $100, you may get lucky.    However, there are also mechanical bits like the shift linkage itself  that may cause the problem.  An Audi specialist, not necessarily a  dealer, may have a better clue than your local all-makes-and-models  repair shop. And given there's a sport-economy-normal switch, there  are also electrical doodads (switches, sensors, wiring) that can  fail.    Your best bet would be to find an Audi specialist and let them diagnose  the problem.  If it does need a new transmission, you'll have to decide  if you want to spend the money to fix it (and an old Audi will probably  have more expensive bits to repair (steering rack, brakes, heater cores,  no-longer-available sensors, ignition switch to name a few)) or to cut  your loses and sell it.    Another option, if the t

ransmission is bad, is to convert it to a manual  transmission (5-speed).  It won't be any cheaper, it may be more expensive,  but you won't have a transmission problem until the clutch needs to be  replaced in 100K+ miles.    Single mom needing a reliable car for work?  You may be better off  with a Honda Accord or Toyota Camry.    --   Kent McLean  '91 200 TQA #3, grey  '99 A4 Avant, V6 Tiptronic  '91 200 TQA #2 blue, up in smoke 2  '91 200 TQA #1 black, recycled  '94 100 S Avant, "Moody", sold  '89 200 TQ, "Bad Puppy", up in smoke  _______________________________________________  Audifans V8 mailing list  Send posts to: mailto:V8 at audifans.com  Manage your list connection: http://www.audifans.com/mailman/listinfo/v8    You can help keep the audifans site running by shopping at http://audifans.com/shop/
