hello guys

i have 2017 MB CLS400 With 9G TRONIC TRANSMISSION 725.0 
and i get fault code P2810 "pressure reguletig valve 7 short to ground"
The vehicle does not travel forward or Reverse , only P/N


in the local workshop told me need to replace all macatronik block
i ask if anyone knows if it is possible to buy the valves or solenoids separately 

I know the dealer is replacing the Mechatronics Completely

advise me what to do?

thank you all

Physically you can change them individually...

I know i can change them.
But i dont find valves or solenoids for this gearbox.

According to the fault code you need to change the 7th valve.
That will need to drain transmission fluid and take out the value body...
Then put them all back and fill transmission fluid and learn or tune if needed.
In case any other valve has problem will need to do that process again.
So some workshop will advise to replace all valves.

Maybe you better also check if there many metal power in transmission fluid...

Provide you VIN then you can order on internet.

Measure first your solenoids. I have seen same problem and my case problem is transmission control unit. Measure solenoid resistance if ok, then measure Tcu internal resistance from solenoid pins, if one have different than others your control unit is bad.
