Yesterday, I did a scan of my W202 C43 and came up with a problem area in the transmission. It gives a error code n° 135 with the info of the Siemens TCU module 021 545 87 32 located in the passenger footwell. I tried erasing the code with no success.

The transmission works fine. A year ago I changed the electronic conductor plate, changed the harness plug (no leak), flushed, changed filter and filled with appropriate ATF. I did erase the error codes at the time and every thing has been working perfectly since

Any ideas what's wrong?
