Sounds like 2nd gear has failed.  Might be seals, might be hard-part failure.

If the gear selector is in 2nd, from a dead stop it will shift from 1st to 2nd as it should, but the RPM drops a bit as if the TCC was engaged.  It will then stay in second until I stop.  When I almost come to a stop, the engine RPM drops a bit as if the TCC was engaged.  When I come to a full stop, it goes back to 1st gear as it should.

I changed the Throttle position sensor a couple of days ago and that didn't fix it either.
