Yes Hello, while driving backwards my car has stopped, then switched back and forth, the arrow does not blink, in reverse it rolls forward now. The mechanical circuit works. When I read out codes 3-1-3 and 2-2-3 I have disassembled once and cleaned the problem still exists. has someone often had this problem and a solution ready? And where do I get a schematic for the automatic transmission from with pin support ung. Thank you in advance
