Did you put the center mid section trannymounts in? The mount on one side is actually clamped to the exhaust and i have the original piece but it is kind of rotten/ twisted because not much structural integrity left. Do you have PN for this?
I actually didn't put in the exhaust mounts that bolt to the tranny, I went with a custom solution instead. That's a good point, I should add those parts to the swap list.
Thanks

I wouldn't be concerned about heat transfer, those ears on the transmission are sufficiently far from the transmission internals that you shouldn't notice any ill-effects.
I actually used only the normal U-shaped exhaust hangers, but filled the cavities with 80A urethane. The exhaust is now firmly held in position and I have not noticed any increase in NVH at all. I'll try to snap a picture the next time the car is in the air, I was in a hurry when I installed them.

I can't say that I'm an expert here, but I imagine that as long as the mount is ~3"+ from the exhaust, you'll probably be fine. Why not make it out of steel like the stock ones?

Have aluminum and easier to work with. I need new tooling for my Mill and i keep spending my money on 6 speed swaps and painting the csi stuff.......
Well at least you've got your priorities sorted

Tony,
this 6speed manual mod description is for a M70 V12 5.0L. There would be more involved for a M73 manual convertion (you could not remove a M73 EGS 9.22 and just use the M73 DMEs and EML IIIs - they are exchanging data via the CAN bus and if this data is not exchanged the DMEs for example pull back some parameters like ignition...)
On M73 you have to simulate the shift lock solenoid on my mod.
cheers

Why did you order the lever from a z3, not from a e31?
I ordered the Z3 shift lever(s) as an experiment for an OEM short shifter. The lever from the 2.8L Z3 had about the same throw as a stock 8, while the MZ3 was about a 25% reduction. It bolts right in and is cheaper than stock by a good margin I prefer it to the aftermarket (UUC, etc) after having owned both types
I'm using the MZ3 lever and would highly recommend it.
MZ3 Shifter Part Number: 25-11-7-527-254, dealer list $69.98

Thanks to the members here...and to Bryson. I now own a 1991 BMW 850 six speed.
I completed my 6 Speed swap. This entire job can be done by one person with a little planning!
The instructions and advice were good enough for a newbie to follow. The factory fresh transmission was from Bret Anderson. The parts were mainly from Charlie Spear at Gault. (other sourcing for certain parts)
Drive shaft balancing by Marty of Long island Drive Shaft.
With a 3.15 LSD, semi-custom suspension and Wokke chips the car is a blast.
The instruction and support came from anyone posting here. Thank you.
Congratulations N! Time to go have some fun

What a interesting post! I have allways wondered how to solve electric on automatic based car but looks like it is quite simple.
How hard it is to find manual V12 trany? Any new units still awaible?

Hi Bryson, can you tell me what was the most difficult part of the swap?
Definitely collecting the parts

I swear, my cars are like a girlfriend.
Sometimes its a rough ride, sometimes its smooth motorin'.
Sometimes she doesnt like how i treat her and sometimes i dont like how she behaves.
BUT at the end of the day, she loves it when I am inside her.
Great thread!
Has anyone rebuilt one of these six speeds?
Current - all are 6mt:
1991 850i
2004 Audi S4
2000 Audi A6 2.7T
I'm not sure why this didn't pop up when I used the forum's search function...
This a wealth of onformation & I want to say THANK YOU!
I've been looking for a definitive guide on how to convert an M70 over to manual, I've just found it. Fantastic information!
I've bought an 850csi engine and 6 speed, it will be going in an E32 750i
