This 6ml tube of gasket maker from Permatex is what we use to mate the output flange/decoupler to the transaxle. There is no factory paper gasket in this location. If your transaxle is leaking gear oil between these two mating surfaces, this is the stuff you need to reseal it. Please note that we include a tube of this in our decoupler installation kit, so if you are ordering that kit, you will receive one of these tubes automatically.
From Permatex:
• Red flange sealant eliminates preformed, precut, paper, rubber and cork gaskets
