Torqueflite taking too long to shift into 2nd gear

It is the valve body that was in the trans when I bought it, don't know brand or low band apply or how much pressure the builder increased it to. I suspect the 1st gear ratio is stock as I've never done a gear change other than have the big block planetaries installed when it was overhauled.
There is no flare up at either shift point.
I launch with both hands on the wheel and put hand on shifter as soon as the front end comes down. When I launched with hand on the shifter I would sometimes pull back on the shifter without realizing it at the launch, so I now leave with 2 hands on the wheel.
I don't watch the rpm on the tach for the 1st shift, I watch the track and see shift light in peripheral vision.
I agree I don't think there is anything wrong with the tranny was just wondering if something simple like band or pressure adjustment would make the shift faster. If not I may have to get a tach with 2 shift lights, which I was hoping to avoid since. I'm a cheapskate plus I just bought a new tach 2 years ago to replace the one that came with the car and is at least 20 years old.

You could always try to adjust the front band, but without knowing the ratio of the lever, cant say what to adjust it to. But if shifts are crisp and firm, and don’t have flare up or real violent shifts from band overlap, and like you said no sign of anything in the pan, probably just need to find the sweet spot where to shift the car 1-2 to reach your desired RPM.
