Many people on here are comfortable with type F

got a new tranny from crt, manual valve body and such. what tranny fluid would work best? thanx jeff
I see from just a quick check of CRT's site that CRT RECOMMENDS ATF+3 with their 727/904 manual valve equipped trannys or PENNSOIL DEXTRON II or III , but again, being it's a new tranny, and that usually means warranty coverage, I'd contact John/CRT to see their actual intended fluid for your application...

So is the conclusion here that a manual valve body 727 would use a different fluid than auto valve body (atf+3 in the manual versus type F in the auto)?
Thanks.

atf+3 WAS a good choice about a decade ago when it was still being made 
You are correct, a quick search shows Chrysler stopped making it in 2005....ATF+4 is the recommended replacement for vehicles requiring ATF+3
But again this thread should not have existed, the OP should have contacted Cope directly for the required ATF required for his application, so as not to void any warranty

I'm not a tranny pro, but as I understand it, common wisdom is that ATF+4 and most other newer formulations are formulated to offer less friction, and more slip because most people don't want to feel the shift in their new car AT's. They do, however resist heat a little better than the older fluids, and one would think they may last longer without breaking down. Type F is an older formulation that has been around a long time, and generally offers more friction; i.e.: less slip at the clutches during a shift. Many racers and performance minded guys like the Type F because of this.
We're talking about very small amounts of difference, however. Most would never know the difference.
FWIW: I run Type F in my manual valve-body 727, and it works just fine.
