Answer 1

E90 335i ZF GS6-53DZ 6速マニュアルに換装可能。

●必要なパーツ
①Clutch switch module (should come with master cylinder, doublecheck) OEM part number: 61319231129 (#20 in diagram)
②MTF-LT-2 or MTF-LT-3 (depends on what label on transmission says, if not check Bentley it will tell you, but from what I've heard LT-2 is the way to go unless stated on transmission otherwise)
③BMW SAC(Self Adjusting Clutch) or equivalent OEM part number: 21207567623 (#1 in diagram)
④BMW Manual Gearbox Shiftier Assembly with bracket OEM part number: (all parts in diagram) (for this one I suggest finding a shifter from a loaner car it will a lot easier since this assembly does not come in one piece, search ebay, etc for assembly) 6. BMW OEM Dual Mass Flywheel or equivalent flywheel OEM part number: 21207542984 (#1 in diagram)
⑤Pedalbox Assembly (Brake and Clutch pedal box with Slave Cylinder attached (if no slave cylinder is attached then obtain it separate) OEM part number: 35006762926 (#1 in diagram)
⑥Engine wiring harness for manual transmission module (if you don't plan on doing the wiring to the clutch switch module and the reverse light, 3 wires pretty straight forward might require proprietary connector or retrofitting) OEM part number: 12517556381 (#1 in diagram (S205A=No (Auto option = No)))
⑦Clutch Master Cylinder (Input Cylinder Clutch(if it doesn't come with pedal box)) OEM part number: 21526773670 (#1 in diagram)
⑧Clutch Slave Cylinder (Output Cylinder Clutch ) OEM part number: 21526785964 (#15 in diagram)
⑨Clutch lines (ones going from the Master to the Slave and from Master to Break fluid reservoir) OEM part number: (#14, 10, 7 in diagram)
⑩Manual gearbox Accelerator Pedal with accelerator module OEM part number: 35426860000 (#1 in Diagram)
⑪Drive Shaft (The automatic one is 1453mm, manual is 1470mm for models up to 03/07) OEM part number: 26107614384 (#1 in diagram)
⑫Manual Gearbox Diff (3.08 ratio (only needed if you have the auto diff from 08 and up as they are smaller and require the diffs to be changed, unlike the ones from before 08 which sport the 3.46 ratio on the diff, so completely up to you if you want to change it out for the longer ratios aka less burn out potential, but better gas mileage)) OEM part number: 33107571187 (#1 in diagram)
⑬Super DOT 4 Pentosin Brake Fluid or Equivalent (Will need to add a little extra for clutch master and slave)

●換装手順
I'm still at the moment gathering all the parts required for this, I will also be linking different DIY's and guides I found online relating to this and I will reference many of them for wiring and such as well. I will update this thread as I obtain the parts and do the prerequisite work. I will also edit the parts list with OEM Part numbers for sourcing, as well as add more tools and such later one. I will also add the wiring diagram.

1. Place car on a lift or use jacks and stands to lift the car by its 4 jacking points (Plastic slots)
2. Remove Plastic Splashguard covers underneath car (8mm)
3. Remove Exhaust completely
4. Remove the 2x brackets that hold the Plastic Splashguard (one is 10mm and other is 13mm)
5. Remove Heat shield for access to transmission tunnel (8mm and 10mm) (Flush the transmission at this point if you haven’t already)
6. Remove the Driveshaft from the transmission (3x 18mm bolts attaching driveshaft to flex-disc, and 2x 13mm bolts holding center bearing to chassis)
a. Before pulling be sure to setup some zip ties or something to hold the driveline up when it is pulled out
7. Unplug and remove O2 sensors (as you remove place a zip tie or label to note connections to each sensor)
8. Remove O2 sensor bracket from bellhousing (2x E10 fasteners) once removed affix it to the side via a zip tie or equivalent
9. In the engine compartment remove the cabin air filters and IAT sensors on cowl, they will simply unclip.
10. Remove the Drip pan (2x 8mm fasteners on the side and 2x rubber clips that simply pull out) Lift up and towards the front of the vehicle to remove
11. Remove upper most bolt on the bellhousing (1x E14) (use a flex head socket to reach tight spots next to firewall)
12. Remove upper most bolt on the starter (1x E12) (Bolt going into transmission) (use flex head socket again) (at this point you can go ahead and remove the automatic transmission harness and replace with manual or remove the automatic connectors from the ECU Box and wire in the brake light switch and the clutch switch module, also remove the cooler lines attached to the heat exchanger on the radiator (this is a closed loop supply, so you can remove the line without problems with leaking out coolant)
13. Go back to underneath the vehicle, support the transmission brace with a jack or stand if you have a lift
14. Remove fastener attaching brace to chassis (4x 13mm)
15. Once removed, slowly and carefully drop the transmission down, you should only have to drop an inch or two.
16. With transmission still held up by stand or jack stick a piece of wood (2x4 or a piece that will fit just right) in-between the oil pan and the sway bar. There should be a little bit of pressure on the wood then push it in. *Watch out for the piece of wood falling out if you are pulling down on the tranny*
17. Grab a long extension ( may need to connect a bunch of small extension to achieve required length) and 13mm swivel socket.
18. Remove torque Convert bolts (There should be a hole near the bellhousing to remove the torque convert bolts (make sure to crank the motor in order to reach all the bolts))
19. Once torque converter has been unbolted proceed with removing automatic transmission from engine by removing the remaining bellhousing bolts
20. Slowly remove transmission from car.
21. While removing trans, have a friend or another person or you, whichever go ahead and remove the driveshaft rear end from the diff (50mm axel nut wrench)
22. Once removed, replace driveshaft insert nut, if you plan on doing that seal if not go ahead and remove old driveshaft and rebuild second half with manual driveshaft piece, or go ahead and replace the whole shaft with the manual one if you went that route.
23. Fill transmission with fluid if you haven't already done so.
24. Route hose for clutch line through firewall, cut nipple to break reservoir (be sure to drain a little fluid out of the reservoir, so you don't spill break fluid when cutting the nipple for the clutch line off as it's location is near the bottom of the reservoir.
25. Removal automatic flywheel from engine.
26. Install manual single or dual mass flywheel to engine with pilot bearing (Be sure to use Red thread locker on these bolts!!)
27. So when I took off the flywheel I was introduced to the pilot shaft, which is actually a seperate piece that sits behind the flywheel to attached to the pilot bearing inside the input shaft of the transmission. After some research it turns out the N55 does not have this and has the pilot bearing within the flywheel like you would normally see it. Pics to flywheel with pilot "stub" http://imgur.com/a/66wtC
28. Install clutch and pressure plate using alignment tool be sure to use some red loctite when bolting in the flywheel bolts, no need for that to vibrate back out of it's place haha.
29. Be sure to remove all the automatic connectors from the trans and lift from the top of the car out the automatic tranmission loom. You will need two connectors on the automatic harness plugged in as well as the ground for the loom, because when you go to program the car the DSC module relays on that ground to function. You will need to just tuck in part of the harness in the ECU box like I did. Just cut off the plastic retainer for the cable and wrap it around. reference for 2 connectors and ground needed to be plugge din from auto loom http://imgur.com/a/oMnaz
