I spent over 4k when I built my 46re in my dodge,sometimes I tow a little heavy. it has about 20k on the tranny with a deep pan and 2 coolers Total 16 quarts and I have done multiple drain and fills at least 4. I am going to put an inline filter on it with a 3/4-16 thread I already bought an xg8a filter but I keep reading about the Baldwin b2-hpg. I am open to other suggestions ,the first filter will only be on for about 1k miles
