How did you clean the transmission control unit? Mine was "filled" with some sort of liquid -- no idea how it go there in the first place. I started by draining it out but that only gets so much out. I was hoping that I can pull the board out of the casing but I have not found a way to do that. In my case the part number of the TCU is 020 545 93 32. Thanks.

The problem is likely inside the transmission -- either mechanical or electrical.

CLEANING IT WAS CRAZY...THERE WAS A WHOLE LOAD OF ATF FLUID ALL OVER THE HARNESS OF THE TCU AND ON THE TCU ITSELF...CLEANED IT WITH MAF CLEANER AND A COMPRESSOR SPRAY GUN THAT LET OF MIXTURE OF AIR AND ALCOHOL...IM THINKING ITS THE TCU/ECU THAT MIGHT BE STILL DIRTY INSIDE OR SOMETHING OR MAYBE ITS BROKE...CANT REALLY TELL....

did you replace the transmission connector and do a transmission service?

dwnsouf7

I CHANGED THE AT "PLUG" THE ONE THAT CONNECTS THE HARNESS TO THE TRANSMISSION..PART NUMBER 203 540 01 53

hows your atf level? Open your TCU up and clean it off with brake cleaner and blow air on it. Make sure you clean out the connector that goes into the plug because fluid sits in there.

and please stop typing with caps lock on. it's annoying.

atf level is ok......wasnt able to fully pry i open but was able to briefly open it to spray some maf cleaner solution inside of it and getting sum residue of fluid....re-cleaned the connectors and cables a little ..lets see if that makes any diffrence cause there is no after market for these tcu...only used/ or dealer available..
