There is a gasket, not sealant. I have managed to reuse the gasket in the past without any leaks. It's just a thin paper gasket.I didn't use any special torque. Tight enough that they aren't loose, loose enough that you don't break a bolt or pull the threads out of the transmission. Or if in doubt just use a small 1/4" ratchet and crank em tight as you can.
