Quick question about the canned 87 tow

[BigSur]

Quick question for you guys. I've been running my canned 87 tow tune a lot lately.....I've really been liking the characteristics of the tune over anything else I've run.

I've started to notice that my 1st to 2nd upshift is very "firm" if I let it ease into gear....vs. if I'm accelerating moderately and/or towing...the shift is easier at higher RPMs. My question is.....is that a problem?...or could it cause any abnormal wear and tear on my tranny/engine? Overall, the periodic firm shift doesn't bother me....I just want to be sure I'm not hurting anything.

Thanks in advance.
