cant drive in snow. not always but very very often when tyres slip and esp brakes the wheels and also happen when esp off, even in dyno mode.
transmission stuck in gear 3 .
gives me one trouble code P2502 .
I dont think that transmission slips at all because it works really well when you floor it in dry road.
not that important but cant do burnout either.

for now i have changed rear abs wheel sensors and those magnetic rings.

and yes this is not first time when I ask about this. hope someone can help me or have same issue.

conductor plate next???

all basic things are checked.
-oil level
-no oil in tcu
-new wiring plug(?) thing that has 2 o rings.
-new oils
-new filter


thanks.

 

Did you scan it with a scanner that can do MB specific codes? You may get more details with a more detailed scan. And if I'm reading you correctly, you mean you changed out the transmission connector and also changed the transmission fluid and filter not just the motor oil. And yes, the conductor plate goes all the time.

 

yes changed transmission fluid and filter.
and yes i'm able to use xentry.

 

Given forum history: https://www.sonnax.com/valve_body_layouts - mercedes > 722.6

 

do you think overlap control valve kit would help?

 

Sonnax is a bit pricey, next step service or replace conductor plate & solenoids.

 

I will try that conductor plate next.
in Finland that sonnax overlap control sleeve kit coast 90€.
