I have a 1996 Audi Avant 2.6 Automatic A6. Recently I had the radiator changed and noticed Oil under the car. When I checked it out I see it drips where the Gearbox Fluid hose goes into the top of the radiator for cooling. My concern is how do I replace the Transmission Oil once I have this repaired? I don't see any Dip Stick or refill cap. Your help will be appreciated.

Ron, do you mean the 2.8 L engine? There is no dipstick on these auto trannys, supposed to be "life-time" fill from the factory. I don't know how, but I'm sure it can / has to be filled after the bottom pan was removed.
