Mixing Type F and Dex? (TH350)

OK, I have a TH350 w/shift kit in my old Ford Coupe....

Don't know much about it as the previous owner just stated it was "Pro-Built" in the Craigslist ad

Checked the fluid and it was a little low on the stick, but I'm not sure what fluid was used

Most manufacturers that build performance street/strip trannies usually suggest Type F and that's pretty much what I used back in the day on fresh builds, but I'd usually do a dry fill with either Type F or Dex2/3 (never mixed)

Odds are they probably used Type F in this tranny, so I topped it up with a quart of Type F, but in case they used Dex instead, would I have any problems with mixing the two?

No problems with mixing in your case.
