Sebring 2001 Automatic Transmission Problems

[SebringLA]

Car drives okay on cold however after transmission warms up it stops shifting at all.

OBD Codes are:
P0700 - Powertrain Transmission Control System (Mil Request)
P0731 - Powertrain Gear 1 Incorrect Ratio
P0730 - Powertrain Gear 2 Incorrect Ratio
P0740 - Torque Converter Clutch Circuit

Ordered Input Output speed sensors, will replace them first, what about torque converter clutch circuit how do i test that?

Unfortunately I don't have much experience with automatics, so I would be dropping the gearbox and rebuilding. But thats probably not what you want to hear. Hope you find a solution.

Changed speed sensors, filter as you can see its original chrysler, fluid was brown.
Magnet had some metal that was soft to touch and very few tiny pieces of metal size of sand that i feel.
Also output speed sensor had same stuff as magnet on it because it has magnet inside.

Check engine was gone but now after driving on 55mph and some city for about 30 miles i got check engine code back however car does drive fine at this point.
