Gasket Replacement

I am giong to replace my solenoid #2 and #1 inside the tranny, but I just wondering if I am using a gasket that I will be getting it from the dealer do I need RTV gasket maker to put on with the gasket that already made? or can I just put the gasket in it without RTV gasket maker? I did once with the oil pan with the gasket already made and I added some RTV gasket maker into the gasket and put it in then after a few days the screw are loosen and the gasket seem to expand, so I want to make sure if I need RTV with the gasket on.. thanks!

The modern transmissions use the sealant without a gasket.

Your transmission does not use a gasket as Brian said.
When you're at the dealer ask for a tube of the Transmission FIPG. This will be orange-reddish. The black FIPG is for engines.
