I just bought a 98 A4 2.8 FWD with the tiptronic trans. The transmission has a slight pan leak. WHen I replace the gasket I was wondering what kind of fluid you would recommend. Also I know the fill is through the bottom. What is the best way to add fluid?. I'm also replacing the water pump/timing belt. What coolant do you recommend?

 

I would opt for the OEM coolant. There is a pump that you use to get the fluid up into the pan. Are you using a Bently manual? There are specific temperatures you are suppose to use when filling the pan.
