[celestron]

Hello guys, I am new here and would like to get some help and info. I have AUDI A6, Automatic, Diesel, Tiptronic and on Reg. 03 (2003) All i know the gearbox code is FWL and engine code is AVF. I require a used gearbox for this car but have not managed to locate one and just when i was about to giveup i came across PistonHeads so thought someone may be able to suggest where would i be able to buy the gearbox. so my request to everyone please tell me where i would find gearbox. any info leading to gearbox is much appreciated. Thanks
