V6 TDI "GHA" Transmission - No Speed Signal

Hi, I have a V6 TDI transmission with the part number GHA, manufactured in 2004. This transmission doesn't have a speed sensor (G22). The car I want to install this transmission into is an A4 from 2001 with a 130 hp TDI engine. How can I make sure that my instrument cluster receives a speed signal? I know that in newer cars, the speed signal comes from the ABS sensor. But how can I extract this signal from the sensor, or if the signal is already present, how can I activate it within the instrument cluster so that it recognizes and uses the signal? ????

Problem solved.
