Shift Kit for 2001 GT

[GREY01]

Hello Everyone!

This is one great message board! Lots of good information here with obviously lots of knowledgeable, interested people behind it. Hope I can keep from seeming too dumb.

I'm a new member with a new car. Just recently bought a mineral grey 2001 Mustang GT automatic. I couldn't pass up the 0% interest and invoice price. Besides, I'll be needing an automatic Mustang pretty soon when I get so old I can't drive my daily driver 1991 Mustang 5.0 LX coupe 5-speed anymore.

I don't like the feel of the GT's stock automatic shift, so I bought a Transgo shift kit from Summitt for it. I thought I would try and put it in myself. Anyone have any advice, lessons learned, etc. from installing these kits? Also, would there be anything wrong with replacing the transmission fluid with Type F fluid? Thanks in advance for any help. I'm sure I'll need more as I add some performance bolt-ons to the car.
