If I keep it in 2nd gear, it's fine, but when it shifts to high gear, it vibrates so bad it feels like the engine is missing

Sounds like torque converter shutter, it goes into lockup in both 3rd and 4th gears. A good scanner with live data can show you what is happening on the waveform pattern, or a good transmission shop can do the tests to find out for sure. Something that worked for me was Lubeguard's Shutter Stop, 1 tube is all it takes. Most parts stores carry it.
