What fluid for my 3550???

[1SLO306]

I going to change the fluid in my 3550 and just want to know what the best is. I have searched and there is very little about what to use. I know they prefer the GM syncromesh, but what is the other fluid i can use?? I just dont want to pay $10-12/qt.

Penzoil makes Syncromesh, and it meets GM's specs. I got mine at Autozone for about $6 a quart.
