Hello!

I bought my self an e34 530i straight six with a automatic transmission. I have started restoring but when I bought it, it only had reverse gear and last owner told me that he just lost all forward gears no rattling nothing no noise at all. What may be the problem and is it worth fixing because I dont want to manual swap it I wanna keep it original also its the electronic 4hp getrag trans.
Thank you!
