5 with new filter
When changing the filter and fluids of a car, it is important to know the fluid capacity. A 2000 Isuzu Trooper uses 9.1 quarts of transmission fluid.
13.8 quarts, or just do 14 and you'll be fine.
5 with filter change
If this is the 3.9 Turbo Diesel it probably would take the same as a 1991 which is 8.4 quarts
4 quarts I had a 2000 eclipse GT
4 quarts
6 quarts
4.5
my manual says for a 3.2l v6 with a new filter it takes 5 quarts
it takes 4 quarts of oil to fill a 2000 Mitsubishi eclipse
8.7 quarts to be exact or 10 quarts to be safe
