Planning on dropping the tranny pan. How many qt will I need to replaced. and Planning on ordering the Amsoil synethic oil, but is there different grade of oil I should order? my car has 160k miles, auto.

Thx,

If your only dropping the pan you can probably get away with 6 qts. There's a lot more fluid up in the tranny, a flush would be a good idea being you've gone as far as dropping the pan.

Here's some good reading material.
