Default TH350 Automatic Transmission

Hello folks

My 1976 TH350 Auto shifts smooth and clean except for second gear which is a bit sharp. Car is an original 23K mile survivor. I was wondering if its just a matter of adjusting the modulator or if a sharp 1st to 2nd gear shift, even at moderate speeds is normal.

Rear diff and trans fluid and filter all were changed and looked good with no issues or metal in them.

The previous owner may have put a shift kit into it.

Probably a modulator problem.
