Hi Upfix, I'm getting code P2725 which leads to a solenoid issue, after replacing the Y3/8y6 B2 solenoid and swapping blue solenoids round I'm still getting the same issue? What can I do from here? Is a new conductor plate my only option now or is there something else I can try? I am getting the same symptoms as all the codes listed in your description. Thanks.
P2725 - Indicates an issue with Pressure Control Solenoid E. This means the TCM detects an issue with the pressure control solenoid circuit. First it's highly recommended to replace all solenoids on the TCM before re-installing back into the valve body. This ensures that the resistance levels on each circuit are within spec. The solenoid itself should be getting between 10-25 ohms. Replacing only Y3/8y6 might not resolve the issue. Also, ensuring the fluid and filter are serviced and the right amount is inside the TCM will help. The solenoids have all been replaced, fluids serviced, and wiring inspected for any shorts and still it's showing P2725 - it's most likely a defective valve body
While we do support that year make and model as it does have a 722.9 TCM, the U1138 points to a network failure with the auxiliary oil pump not the TCM. Check the CAN bus connections, the wiring and plugs for any issues, and lastly inspect the auxiliary oil pump itself for any faults.
@@upfixauto i replaced the tcm and now no code . But am facing an issue when i kickdown it stuck on 5500rpm and not shifting in any gear. If normal drive it shift perfectly and smoothly in any gear at 5000 rpm. Am facing this issue before and after the tcm replacement
@MaanzMotivation Yes, that is a strange one. After a TCM replacement, the transmission may need an adaptation or reset procedure to allow the TCM to relearn shifting patterns. This is particularly common in Mercedes-Benz transmissions. It can often be done via a diagnostic tool.
Excellent work guys. Thank you.
Thanks for watching!

In my case am getting code in w212 2012

Were can I send it in to?

If I accidentally broke a piece of the conductor plate and the ribbon broke as well, can you transfer all of my components to a new plate for rebuild?
