Dave Kan's E28 Transmission Swap My E28 Transmission Conversion. As told by Dave Kan (10-18-99) If you have comments or suggestions, email me at dkan@america. It all started a few months back when my good friend Steve Jones called me up in the middle of the night (I had been sleeping) to tell me that he had purchased a transmission for me. Transmission swap thread omnibus | BMW CCA Forum Apr 01, 2009The small 6 E28 is a little different. You need everything above, but you can only swap from another small 6 E28 for the flywheel/clutch/release bearing, transmission support bracket, the shift support and linkage, and the driveshaft. You cannot use a big 6 trans. This will not prepare you for a later big 6 or S38 conversion.
