Depends on the type of connection I beleive. Two flat surfaces need a gasket to account for thermal expansion/contraction. However, on at least the 97+ Trans Sports, all the connections are made with joints that's aren't "flat". One side has a flange that is slightly conical (think like a funnal) that fits into the other side. It seals without the need of a gasket as it can expand and contract without loosing connection.
