Automatic transmission Audi 100 Type 44

Hello dear Audi community, I would like to ask for your help. So, I’m looking for an automatic transmission for the following Audi 100 type 44 2.3e MKB:NF GKB:REH. And I need a REH 3 gear transmission! I already know people who would overtake me! But would like to have a 2 what ok if something goes wrong or so that I can continue driving! Google, ebay and I’ve got forums through, but it can be that I’ve missed something. Technically it should be flawless, maybe under 100tkm! Priced depending on the condition! Would be top if you could help me……. Thanks, MfG Rennaudi
