1999 Sebring transmission question

If no check engine light or hard codes, watch the input and output speed sensors with the scanner. If they both show RPM.s when the car is moving it probably has an overdrive hub that is broken in the front of the transmission. They had some bad welds on them back then. I have rebuilt thousands of them. Could also be the underdrive/overdrive snap ring is broken too. Hell I think that transmission paid from my first house. It's an easy fix, but pulling it out without a lift would not be a fun day at all.
