Found this...
"Fairly common problem with T56's. You either sheared the teeth off the cluster gear and main shaft for 5th and 6th, or you have a broken shift fork/shift pads".
Since you didn't loose reverse, it sounds like the mainshaft. Time for a teardown and rebuild.

Trans come out of a wrecked car? That may explain internal stress related damage that is now coming to the surface.

You drove it a few miles and then it started working in all gears? Very strange!

Did you fill it with Dextron lll fluid? It's a manual trans that uses ATF. Sounds weird but it's true. If you didn't use that fluid it can and will cause shifting issues.
