Default 4L60E No high gear. Help!

First and second gear are solid and shift fine. Shifts into third feels like neutral. Letting off gas shifts back into second.

Your 3-4 clutch pack has gone out. Time for a rebuild! Common 4L60E problem that happens when you start making any kind of power on a stock 4L60E, particularly with an H/C setup from what I've heard.

Yep, been in that situation. Time for some clutch packs. Do yourself a favor and spend the money on a built tranny instead of going back stock.
