Brass or Dacron transmission filter

I prefer a good filtering Dacron also for 98% of what I build. A few yrs. ago as a test I used a Dacron filter in a race trans I built that had a manual VB and it showed no evidence at all of fluid starvation. It wasn't a super fast car though (11.0's) so with something faster I suppose it's a possibility.

Even if you use an external filter along with a brass internal filter and magnet there's always the chance of some aluminum or brass shavings from a planetary or thrust washer dropping down into the pan and getting sucked through the brass filter. When that happens the first thing that happens is scoring in the valve body and can also eat away at seals.
