Calling all AX-15 experts

Here's my question/dilema.

I had my AX-15 rebuilt when I was doing my engine swap. I have just never really been happy with the shifting.

Basically the symptoms are that when I'm shifting with 3500 rpm or more, I can feel and hear the synchronizers engaging gear to gear. They're not grinding, but I can feel it through the shifter and can even hear it with my loud exhaust.

If I double clutch or shift under lower revs, this does not happen and it shifts smoothly.

When I took it back to the tranny shop where I had it rebuilt the guy told me that since I'm running full synthetic (Royal purple synchromax) I will have noisier shifts and that it's shifting normally.

So my question is: Am I just paranoid? How noisy is noisy with synthetic? I've typically been of the mind that even with light oils you shouldn't be hearing the syncrhos.

Any thoughts?

It sounds normal. I typically don't shift higher than 3200 RPM's just to be nice to the tranny.

I don't rev it that high to shift unless I'm in four low. And it sounds about right. Synthetic is noisey it seems. I put royal purple in after my rebuild and it makes the tranny whine a little. All in all it seems about normal. Nothing wrong with bein paranoid though. I think we all are sometimes, especially with driveline components.
