Guess this transmission part
 

Hello all
i dropped the transmission pan on my 90 727 auto.
Pan was free from significant metal shavings, etc. Fluid seemed ok, but dirty.
i did find this piece in the pan, however.
curved, non metalluc piece approximately 1/2 x 7/8 long, slightly curved.https://cimg0.ibsrv.net/gimg/www.die...66c0dfa9af.jpg
