You're correct in your assumption about the Powerglide being easy. I've done 727's, and the Glide takes about half the time.

I broke a 1.76 planetary and it did still lurch when you put it in gear, so a good chance you broke the input. Are you using a stock input shaft? I would upgrade to at least a 300M if so, though a Vasco is best.

If the planetary is good, make sure you check the end play on the gears in it while you're there. I seem to recall there should be .02-.03" between the gear and the planetary housing.
