I'm trying to convert my 79 264GL tranny from a 3-speed BW55 to the AW70/71. I found the donor car (86 760GLE w/B28F) but have come across a problem. The AW70/71 out of the donor has no place for the speedo cable. It must have an electrical sensor in the differential for the speedo. I would like to know if anyone has ever made this type of tranny work for the mechanical speedo? Another question I have is I know that the 4-CYL AW70/71 tranny's have a different bell housing than the 6-CYL AW70/71. Is it possible to swap bell housings on this type of tranny? I could get the bell housing from the donor car and just try to get a tranny from a 4-CYL. Any and all info would be great. Thanks to all in advance.
Sincerely,
