low budget bracket racing blues

What convertor is in the car? I had a TCI years back (when they were decent...) and one day it just started whining... Like a gear drive sound, but only in gear. It was the stator bearing in the convertor. Sent it back and they replaced it for free. It did not make a peep in nuetral or park. And no problem with coasting in nuetral... Been doing it for years and years. I use ATF+4 or synthetic. I'd rather have lower temps than thicker.
