Unhappy WH Auto failing

My jeep went into limp mode and locked the auto yesterday and again today. It's throwing codes P2784, P0717, and U3FFF. I cleared the codes and it ran ok for a few ks, then the auto locked in one gear again shortly afterward. I'm hoping its just the turbo/speed sensor. Got it booked in for assesment monday.
Fingers crossed.

Limp mode not failing.
I will say its the speed sensor on the NAG1/722.6 (auto) conductor plate, not a hard job.

U3FFF is the Jeep swearing at you.

Does the conductor plate on the valve body need to be replaced entirely or can you replace the individual sensors ?

Thanks

Yes the whole plate. Just be carful when buying its not a Chinese copy, I would stick to genuine Merc. If the price is under $200au on line then I would be sceptical.

example : This looks like German but BAPMIC its made by Shanghai Tongzhi Auto Parts Co., Ltd.
