Is there any thing important I have to do or schould know before it is to late?
Are there any gaskets I need to replace?

 

The only gasket I replaced was the pan gasket because I changed my filter while I was at it. Some recommend changing an O-ring, I think it's where the converter neck plugs into, but I didn't because I didn't find out about it until after my converter was already changed.

 

Take a look at some of the other TC install threads that have been posted

I didn't replace any gaskets or seals when I did mine. I checked everything out and it looked ok. So I moved on.


good luck!
