  • BMW toTH400, Powerglide,4L80e trans adapter

    Alien Engineering BMW to GM trans adapter. This is an adapter for installing a GM V8 automatic transmission behind a BMW inline 6. Includes a billet bellhousing adapter and a billet crank adapter to use a Quicktime SFI flexplate part number RM-949. Includes all the required fasteners to bolt the flexplate and trans to your engine. Will work with any GM V8 automatic trans such as, Powerglide, TH350, TH400, TH200r4, 700r4, 4L60e, 4L80e, 6L80e, 10L80e ect...


    Uses a stock M50 unthreaded starter motor and in order to allow for stock starter location the trans bellhousing does require clearancing. I typically have these in stock but if not it will take around a month to get them machined. Please email to inquire about lead time.


    Works with the following engines

    M50, M52, M54, S50, S52, S54, M42, M20
