Car
2004 Audi a6 Quattro 3.0 v6
23,900 original miles

Ok so we picked this car up from my step dads parents who bought it new in 2004 and It actually sat from 09 untill we picked it up last month.

So the car is great clean like new. Except it sometimes bangs/jumps into gear when shifted from park to drive or reverse and if it does that then web we pull off it started revving like neutral all gear lights on and you have to pull over to reset it then drives perfectly ok. Shifts very smooth even if in sport and mashing te gas . I was thinking it could e fluid? I changed the oil and it was very old and almost like water . From sitting maybe ? The trans could be the same ? I'm just not familiar with automatic transmissions at all. But I'm up for any job. Any help would be great thanks !

Also I have searched and although some similar issues out there I just couldn't find te exact same especially with low miles .

Also car doe not shake or anything this car truly feels brand new. So I don't think a motor mount or anything although I could be wrong ..

 

scan with vag com, the lighting up of the gears is the tranny, change the fluid, see what happens.

 

My guess is since it sat from 09-2012 the only reasonable thing to suspect is the Tcm has gone bad. Was the car garaged or parked outside? Check under the passenger carpet. Make sure the Tcm isn't wet. And scan the car for codes. Buy a vagcom from eBay $10. Best investment you'll ever make for the car.

Hopefully the seals in the tranny haven't gone bad from just sitting.
