E53 5speed To 6speed Swap.
My car is a killer in rpm on the highways at 80mph and 4grand rpm and was thinking to swap the 5 speed I have to a 2004 x4 6 speed trans and would like to know if it’s a direct swap for this or I have to swap out the transfer case and drivershaft.
Tired looking at the realoem parts list but the 2004 X5 6 speed is not listed just for my 2002 X5 show the parts listing but at the diagram looks the same for both years. Thanks Jp |
Lots more to swap that just the mechanical parts (transmission, transfer case etc.) - there's all the transmission control electronics too, along with the transfer case controller etc. Massive task - including a huge amount of re-programming.
While such a swap might be possible, it might be easier to just sell it and find a 6-speed car.... :rolleyes: |

From fading memory, someone/someones have done it...try Search.
Back at the High RPM Ranch, would the cost of the 6 spd trans and accompanying costs of the possible swap really be cost effective, other than for lowering highway rpm a ~ thou and maybe your piece of mind? I get the highway high rpm: I have had an '01 E53 5 Speed since new, and quite familiar with the high rpm at highway speeds... Not sure the 'cost'/aggravation/process is worth the effort, but everyone has their own bag. GL on your search and project... mD |
Another option to lower the RPMs at highway speed is to put the differentials from the m62 e53. Some members here have done this and I think it lowers the rpms at 70mph by 500 or so. That would be much easier to do and to locate the parts. Cheaper as well.

I was thinking of this as well and thanks for the info! |

So yeah, much easier. But the transfer case issue is the same... unless you can get the NV125/LWX500 transfer case to fit the 6-speed trans, you are looking at a full xDrive retro-fit. :yikes: |

I’ve actually grown quite fond of this formula! Especially with a 7000 rpm redline. |
