    The GS6-53 gearbox used on manual equipped 545, 550, 645 and 650 models will fit the N62 engine. The GS6-53 used on the S65 M3 as well as the ones in the 335i and similar I6 engines will not fit so make sure it's from an N62. You would likely need to custom fabricate a transmission mount (although 5 or 6 series parts *may* work) and shifter carrier as well as shift linkage. You would also need some custom work in the center console as the E65 did not come with a manual in any markets that I am aware of. Not sure where you'd put the shifter since those have a column mounted shifter selector. Driveshaft will likely need to be custom unless 5/6 series parts happen to fit. It will need to be re-coded a little bit as well and that may not be an entirely straightforward task since the E65 never came with a manual. Most likely you'd use E60 or E63/E64 coding, but I am not sure it will play nicely with all the E65 modules when coded like that
