3rd gear transmission slip

3rd gear transmission slip
I've got a 1970 442 with a 455 and TH400. For years I've had a slight stutter/slip when shifting from 2nd gear to 3rd gear if running full throttle (no big deal because it's not often that I'm full throttle going into 3rd).
In any case, I just changed the radiator over the weekend. Now the first time on the throttle somewhat heavy after the radiator was installed, it didn't want to shift into 3rd unless I let off the gas. Then it seemed to slip more than normal in 3rd. ...but under normal light driving you would never notice it.
So the question is, could this be something related to the transmission cooler in the new radiator? Or is it just a coincidence that this problem is showing up at the same time? When I hooked up the tranny cooling lines I did have a small leak at first, which could have introduced some air, but I would think the air should have worked itself out by now.
Any thoughts or input on how to fix this or what could be causing this are appreciated.
