I did Dot 5 in my 78 T/A. My mechanic reeommend it. He owns an all GM repair facility, Plus like said here, when you bleed the system, all the detailed painted parts don't get ruined. It works great. However, I replaced my lines and had everything rebuilt, only flushed out part was the prop valve.
The fluid in the back when I did it was nasty. Dot 5 is the way to go. I was just thinking, it's been 17 years already, time for a flush and refill.
