Is it only having issues with the 1-2 shift or is the 2-3 late too?

There isnt really a lot that can go wrong in a TH350 to cause issues with 2nd. IF it shifts gorrectly into 3rd I would say you can pretty much rule out a vacuum modulator issue.

Some things it could be are 1-2 accumulator leaking, 1-2 shift valve sticking, intermediate sprag not functioning properly, or possibly a governor issue but I kinda doubt that.
