Hello there. I am in need of help. I am looking for a part for the gearbox of my A4 Tiptronic and am new to Audi and do not know where to find it. Serial of my Audi's gearbox is 01J series GYJ. I can provide the VIN as well. Any help you can provide is greatly appreciated. The part is inside the gear box and it is a long shaft with a pinion at the end that matches up to what is called here a "crown"?? Please help :-(
