I saw some guys on a thread saying to leave the seal.

But I know nothing about this trans. I bought a pan with a drain-plug for my car which also has a drain plug in the torque converter. Really easy now to change it all.

I'd say you are good if there was no build-up of friction material in the pan or loads of metal. -BA
