W204 Auto Transmission

[malguy]

Good day guys,
Need some advise here, I have a C200 W204.048 with 722.696 trans at my shop now with transmission slip & lock to third gear. I diagnose with star and come up with fault code 0730 & 0733, I also found that the adaptor for electro plate is leaking atf. I replaced both with new filter & fluid.
Now it only shift to second gear & come fault code 1731, anyone here seen this before ? I have also check the TCU, all dry & clean inside.
Any help would be much appreciated. I am tearing apart the trans now to see if there is any mechanical failure.
Thanks.

Best regards,

Thanks for input, after open this gearbox, we found input shaft, disc support & freewheel bearing are badly worn, friction plate have burn mark. But fluid lever are normal, maybe low on fluid for sometimes before owner send car to me.
Any suggestion what have cause this ?
Thanks.

Regards,

посмотри параметры вращения скорости датчиков, турбины и промежуточного вала: промежуточный вал показывает скорость с 2 передачи и далее, а так сгорел или нет контакта на датчик скорости промежуточного вала
