Hey,
I was driving and after 210km the car loss the power. I stopped and restart the car. PRND started flashing. I connected autocom and it showed me TCU error. We removed the tcu and got it repaired. After install there were no flashing PRND but the car doesent have any power, it moves slowly and little bit faster reverese way. Autocom doesent show any gearbox errors. Any ideas?

How to know wich gearbox will fit? (I have FSG)
