Trans fluid in dana 20

Green-Machine · Nov 28, 2020

Hi everbody, I had my transmission rebuilt, and dana 20 resealed. For some reason I have trans fluid in the dana 20. (The drive train has zero miles, Only started to move it around)

What seal could have been installed incorrectly and could I have damaged it when I install the transfer case?

The double lip seal must be installed correctly or the trans pressure will blow out and into transfer case.

Also I forgot to completely attach the cooling lines when I started so it puked out some fluid. It didn’t run long before I tighten them and added fluid. Is there any possibility of pressure building up and blowing that seal?

Figured it out, Ding dong that resealed my transfer case decided it would be better not to install the seal.

It doesn’t take much pressure to blow that seal.
