The transmission that is probably in it is a GM 4L30 auto. I had to rebuild the one in my old 328i. Hope this helps..

4L30-E Manufacturer General Motors
Class 4-speed longitudinal automatic transmission
The 4L30-E was an automatic transmission developed and produced by General Motors. It was developed for light-duty use in longitudinal engine rear-wheel drive vehicles, replacing the similar TH180/3L30. The 4L30-E was used in many European and Japanese vehicles, including the BMW 3- and 5 Series, Isuzu Rodeo and its derivatives, and Opel Omega/Cadillac Catera. It was replaced by the 5-speed 5L40-E/5L50. The 4L30-E was built at GM's transmission plant in Strasbourg, France.
