Problem transmission 722.6 it is not solved after replacement

My car is a MB C-240 sport 202.026 1998 the transmission is a 722.6

The story is the following

The car did not make changes and was only in first gear, when changing from R to D or D to R it hit or kicked

1. The contact plate was changed and this frame error in the temperature sensor
2. the plate was changed again and now I mark codes in the solenoid A and C
3. All the selenoids were changed and it continues to indicate the same code
4. Now to test the transmission was changed for another and still without making changes

some help or advice to solve this that is breaking my head.

Did you check the TCU..?, it may go bad, or oil sneaks inside the TCU..!?!

I have not checked the TCU, how could I know if it is good or bad, in the transmission there are no leaks, in the TCU I need to check for leaks.

Sure, trans. hot oil can sneak to the TCU module, and damage it,,

have to pull out the passenger floor mat, and you will see it at the back of the alloy floorboard..
