From memory i would say the auto is about 30mm shorter. I uesd the manual one, but you are keeping your own diff you only need the front half. if you look on BMW REAL OEM,COM you will find all info on parts and part numbers.

[GnomeChild]

So is there any difference in output flange sizes between Automatic and Manual transmissions (where the guibo mounts)?
I ask because I am trying to frankenstein a driveshaft for my M3 LSD swap and want to source a second front-half driveshaft to harvest for the flange swap on my M3 shaft instead of cutting up my original manual driveshaft.

The OP said that only the back-half of the Manual driveshaft is different and comparing pictures on ECS tuning, that seems correct but I just want to be 100% sure before I make a commitment to buying parts
I am watching a few front-half driveshafts right now but I just wanted to know if either shafts will work for my purposes (just in case maybe they are mislabeled or send the wrong part)? I’m also assuming no difference between e90/e92 shafts

Just did this.... very helpful

hello again dave

you are correct, the difference between the two shafts is 30mm.
i am keeping the auto diff yes, and since the gearbox coupling fits the automatic shaft, i did not need to cut and weld it.

i just extended/ pulled it from one end to another and it works.

now the only hustle is i cant seem to find a straight forward reverse wiring diagram online without bringing up reverse cameras and all.
i am using a manual DDE for now (to avoid the fan running non stop since i am not able to code at this point), i have the plug and wiring but still need to figure out were to plug it on the DDE.

apart from that, the thread has been very helpful indeed...thanx alot

Run a wire from your reverse light switch to ground, run a wire from the other terminal on the switch to pin 19 on your FRM unit. if the car is coded correctly the reverse light and parking sensors will work. The only trouble with just pulling the shaft on the spline is it hasn't got as much strength because the contact area between the two is less than it should be.

The guibo is the same on my 335d the drive shaft is shorter on the auto, as for the M3 i wouldn't know.I converted a E46 M3 in 2008 but that was easy, just standard M3 parts and 2 wires and recoded the clocks.

u are very helpful and i appreciate that.
i have not done any coding yet but i strongly believe it will be straight forward as i have installed a manual lockset . i still need to buy software and cables off ebay for the coding.
i will try connecting and setting up the reverse switch today and advice.

as with the shaft. what you say does make sense but i still have to verify

The shaft will fit but don't go launching it off the line, if the shaft comes apart it will wreck the floor pan of the car..

[stuta]

yes dave, there will be no launching the car until all is sorted and perfect.
am doing it one step a time till next year...kinda like a project

and by the way, are u able to source me a second hand gear selector from from scrap yards for a e90 330d that side. have checked on ebay with no luck...most are in Lithuania and it takes a while to arrive if one buys from that side.

[RS DAVE]

To be honest those parts aren't that expensive from bmw, and they will feel like better as all the bushings will have no wear.

[stuta]

I think u hv a point thr sir dave.
Thts wht I'm gona do

just a quick question dave, u have been a very big help and i owe my car driving to u.
the thing is, on the frm module pin 19. there is a blue wire. do i cut it and connect the end from the frm module to the one wire from the reverse switch or do i simply spline and bridge it on without completely cutting it?

i hope my question makes sense.

thank u again dave

PIN 19 is were it goes so just remove the wire that's there and give it a go. the one that is there may go to the auto trans shifter? you could try a test on the wire to see if it does go to the shifter,

Dave how has it ran since doing this yourself? I did this to an FD RX-7 ten years ago and it was... an undertaking but not horrible.

I'm wanting to do this as I keep putting more bulk in the engine and I can feel slipping and burning clutch... for an auto. This ain't a good thing. That being said I'm just curious if you ran into anything over an extended period of time that caused any alarms for you.

Thank you Nick for doing this expansive write up and giving us all advice as we've needed.

Sorry for the slow reply, my dad died so have tyied up for a few weeks. nothing has gone wrong since the day i did the conversion, i used all standard 330d m sport parts, everything seems up to the job,the car has a 360 bhp remap and all is well. if you go on facebook, find BMW ADVANCED CODING, if you scroll down you will find my car reg 516 MOB there is a short video of us driving it just after the coding.

Sorry to hear about your loss. After driving an auto E46 for nearly seven years, I jumped at the chance to replace it with a six speed E92. Best mod ever!

Thank you for the reply man and I am saddened to hear of your loss. Take whatever time you need, don't worry about anything over here.

Anything you need to know just ask.

Hello, I am doing this to a N55 , and I am running into some issues.

1. in the left of the clutch there is a white 4pin plug coming from the main harness, is it related to the clutch stwitch?
2.do I need to buy 61116911072 (plug) if I have the plug from the switch and 2-3inches of wires(cut from the donor car)?

3. The Automatic gearbox harness is only 1 big circled plug , is that the one I need to get the ground pin from?(for coding)


There are many other unknowns but these are the next steps I should figure it out before my flywheel (I am going with DMF)and QUAIFE diff arrives.

Thanks in advance.

Catalin

Did u manage or do you still need assistance?
I converted a e90 330d from auto to manual and the car starts and drives fine.

Only issue is i can't bet around the coding.

Dave, its been a while

I bought INPA off ebay with th k+dcan cable....
My ncs expert profile has no expert mode and i cant code my car meaning the fan runs non stop....any shooters.

That's because the dde isn't seeing a signal from the auto box, so it thinks the box is overheating. there is a thin trigger wire that runs along side the 2 thick fan wires, brake into it with 2 core wire and put a small switch on the dash. when you need A/C you will need to switch the fan on, as of yet know one has sussed a way round it. even when you code it, it will still do that.
