Fiat Freemont 2.0 Multijet AWD 62ET Transmission: Persistent Emergency Mode Despite Repairs

Hello, I have a problem with the transmission in the Fiat Freemont 2.0 Multijet with AWD drive, the transmission is 62ET. The car caught the emergency mode the day after a long route. The multiecuscan program showed errors:
P1790 - Fault Immediately after shift
P0735 - Check gear ratio V gear
P0792 - Excessive change in output speed
P0732 - Check gear ratio II

An attempt was made to regenerate the chest. When dismantling the box, worn OD / UD friction discs were found. The ordered repair kit for the box (set of friction plates, set of O-rings, set of seals outside the set of repair of solenoids). After assembling the crate, mounting in the car, pouring oil (ATF 4+), the errors were cleared. After starting the car and trying on the lift, the car threw back the same mistakes. As I have a second box for this, I have replaced the solenoid valve assembly, but it did nothing.

I would like to ask more experienced colleagues for some advice where I could still look for problems, because this was my first adventure with the automatic transmission and I just lack ideas.

Below are screenshots from the multi-task scan and a photo of damaged discs with spacers:



Thank you in advance for any advice, best regards Damian.

Have you replaced the output speed sensor (error P0792)?

Yes, the sensors were swapped, nothing changed

Hello, And you dealt with this problem because I have the same and I don't know what to do anymore

I raise the topic

How are you guys? Have you figured out the issue with these errors? Because I have the same problem... Regards

Have you replaced/checked the gearbox block and solenoid valve? We also had other errors, including 0868, after replacement the problem disappeared.
