Hello I am brand new to the BMW world. I am a fair DIY mechanic and I would like to learn the basics about my 1994 318. I know that the engine is an m42 but I was wondering what tranny I have. Its an automatic. I would like to swap it for a 5 speed. I also have a spare m42 and plan to build it for boosting with a kit for Metric Mechanic so I would like one that will hold up to that. Also is MM the best place for buying parts. Any info would be appreciated.
