4L65E SWAP to TH400

I'm looking at making the swap here in the real near future and was trying to get some information on the swap before hand.

What are some of the problems, concerns, issues when making this conversion?

What have you noticed about your setup afterwards?

Anything else relevant to this swap that you think is of importance?

There are a bunch of threads if you do a search for TH400 and also a bunch of info in the FAQ. I'm in the middle of doing a TH400 swap into my GTO as well. If you originally had an automatic you will have to change your tune to a manual car tune.
