Not holding 2nd gear?

Well after the build, been driving truck for a couple hundred miles, shifts fine in all gears. So I decided it was time to train tow haul. Probably 12-14 lite passes (1/4 throttle and up). Can't tell if its hanging 2-3 shift or if its just not holding the power in sec. Not making that much power btw. When it hits 3rd it feels good. All other gears feel good as well. Was going to reset TAPS again. Any thoughts?

Also want to add, when I tore it down both Trim solenoids were completely packed full of crap. I cleaned thoroughly and reassembled. Thought about replacing them both, just don't want to throw money away if thats not the problem. I would think if it were the solenoids it would affect all gears

Yes, tow haul only. Now that you mention it, I did go back to an 01 tcm tune that I used to run. But it never had issues before.
