E46 M3 SMG to Manual Conversion DIY (On Jackstands)
HTML-код
- Опубликовано: 23 авг 2020
- In this video I show you an overview of the process it takes to convert your E46 M3 from SMG to a 6 speed manual. I didn't try to make this video to show you every single minute detail but I hope it serves as more of a guide to refer to. If you have any questions regarding the swap, please feel free to drop a comment below and I'll try my best to answer it for you. Below are some links I think you'll find helpful because they definitely made this job possible for me.
Here's a part 2 video I made to supplement this one: • E46 M3 SMG to Manual S...

LITTLE UPDATE: My friend Jeppe had been tracking down why his cruise control hasn’t been working and it’s because at around 28 minutes into the video I explain how you need to wire into pin 20 on the connector that is the second one from the left but it is in fact the connector that is the second one from the right. Although messing this up won’t compromise the driveability of the car, it will make it so your CC doesn’t work. So if cruise control is important to you, be sure to fix this mistake I made in the video! Thank you and thanks to Jeppe for figuring it out!
Thanks for the update. I bought a conversion with non functioning CC. Will check the pin. Any other common reasons on swaps you’re aware of?
@@kraken509 check the clutch switch! if it’s black and not brown, then that would cause a non functioning CC
@@jinendow mine is black! Good call.
Cant thank you enough for this! I am starting the swap tomorrow and you helped answer a lot of questions that I had!
that’s awesome to hear, that’s exactly why I made this video! good luck with the swap and if you have any questions during the process, let me know
nice job! i was getting nervous about the wiring part. But after watching this for the 4th time, i feel like i can do this.
wiring is super simple, you got this!!
I can feel your joy 2 years on! 😂 Nice work.
Props to you for a great job man. You got my respect for this DYI job. Bless
VEGo 88 thank you! I appreciate it
Jin Endow yea man i have an 06’ and i’m trying to work up the faith to take the same approach.
VEGo 88 just give yourself enough time and the the job should be pretty simple!
Jin Endow thanks
Nice Video end Job ,man Great swap
Nice job 👍
Great video
Demonic presence thank you !
about to do this after fighting with my smg for a month…. i knew i should have jumped right in!!!! third time dropping the trans now.
hell yeah good luck!
did you find out why the smg wasn’t starting the car though ?
I've got a 1999 328i that had a 5l40e five speed auto. I installed a six speed manual from an 05 z4. I'm getting an S indicator where the gear indicator is. I've wired the dme and the ews still won't turn...
Good job on the video, decent coverage of the steps.
Regarding the trany, since you had it all out, did you replace any of the compression springs? Did you install the locking pin and thrust pin? also noticed no ID switch, any issues with that? Im just trying to get all the parts I need in my basket as we speak... will be doing all the seals (inner and outer) as well since its out.
I did not replace any of the springs unless that is covered under Lang's Bellhousing machine service. And the ID switch isn't really necessary if you get the proper coding done afterwards. Good luck!
Best thing you can do to ANY car IMO. Doesn't matter if it's an E46 or a freakin econo box like a Neon. Three pedals or nothing is my motto. Makes it so much more fun to drive, and obviously you have a lot more control over the vehicle. The SMG sucks ass compared to the later DCT trans' anyways so regardless it's the better move. The DCT is WORLDS BETTER if your into auto trans.' SMG's are always so 'clunky' shift really rough, especially at lower RPM. Makes anyone look like a noob when you're driving. S54's are so awesome that having that crappy SMG bolted to it is really a buzzkill. I'm a VW/ Audi and BMW tech that's been turning wrenches on these and pretty much anything with an engine for a little more than 25 years. The amount of SMG failures I've seen alone also makes this swap mandatory IMO. Like a completely different car with the manual. Good video. Thanks for sharing man. 👍
I 100% agree! been a few years since I made this video and haven’t regretted a thing
@@jinendow definitely man! I've swapped to manual trannies on a good amount of all kinds of stuff over the years, and I've never had a customer or a friend that I've done the job for that's been disappointed whatsoever.
I did the swap, but fuse number 3 under the hood is blowing. Its a 20amp fuse and i used a multimeter and saw that the brake light switch is connected to this fuse. Did you have any fuse blowing?
Hey Jin. where you able to source clutch switch #613 or you just stuck with #354? I actually ordered 1 supposedly the #613 but received #354. I want to know if you are still using #354 and what are the issues you have using the #354? I also plan on using ECUWORX for coding part of it. Thanks a lot for your time.
Where did you get the female pins from, to add to the DME and EWS connectors
Great video. Quick question, why did you choose to modify the bell housing with the RTD Shifter? Can’t you install that shifter with the RTD and avoid bell housing modification?
thank you, yes you can use this shifter and not modify the bellhousing. I just read a lot of differing opinions on the forums and saw that some guys didn’t really like the shifter feel when the bellhousing wasn’t modified. I just thought I should play it safe
Hey do you have the part number for those wire that you purchase
Most underated youtube channel. How much did the entire thing cost.
cool osmani thank you!! I appreciate it, and the parts in total came out to about right under $2000
Jin Endow wow thats pretty good. Now i just need to find a cheap m3 with a smg lol
@@jinendow under $2000, what exactly do I need then? I’m currently in the middle of loading up the carts with parts to do so... but I’m in the talks with someone that’s trying to sell me his 6 speed tranny the driveshaft a clutch/flywheel and the pedal assembly for 2k
@@axelgomez9022 click the forum link in the description and I’m pretty sure there’s an extensive list of what you need there
@@jinendow thank you so much!!! Didn’t even think to check the description for some reason but thank you!!!
I’ve watched this for 5 hours now
are you doing the swap?
Hey, I was lookin at an M3 at the time but plans fell off, and I’m doing the same again. Have you heart about the swap with the self centering shifters? Manual bell housing and stuff are so darn expensive now
Great vid, I might have missed it but how did you mount the bracket for the shifter under the tans tunnel? Ive seen some weld it, some used rivets, how did you do yours? Not sure what its called. Thanks.
I actually did not install the bracket! since the rtd did not require it I opted not to install it for time sake. down the line if I opt for a stock style shifter, I will have to install one
Awesome walkthrough man, I'm also doing a SMG to manual swap on jack stands and I got 2 questions.
1. I have an EWS delete so my EWS module isn't plugged in. Will that cause issues with the one pin that goes into the EWS plug?
2.I also have a Buildjournal tune, I know on they offer re-tuning and they have an option for "I am now SMG". Is that all thats needed to clear the smg cog? or is more tuning needed?
Thanks
if you already have EWS coded out of your car I don’t see that being an issue
you will need more than a retune from BJ
Was that a bottom end noise?.... lol.. kidding.. Nice work!
Hoping you can answer this but I'm doing to soon but to a 330ci
Is this the same as the Non M SMG?
Nice video man! Had a quick question since it’s a manual now did u disconnect the smg tcm completely or is it still hooked up with no cel? Reason I’m asking I just purchased an m3 and has a manual swap in it but has a cel and checked codes and all are smg related but the car runs fine.
baboosted I have the smg tcm still connected with no cel. I’m not sure if your car got fully coded. my car had a cel before ecuworx coded it remotely.
Jin Endow oh ok thanks man
Hi my name is Carlos, I own a SMG e46 m3 with a SMG problem are you in the Los Angeles area?
Hi,
Great video mate! Wich pin have you bought for the DME and EWS? 0.25mm², 0.5mm² or 1.00mm²
this is the part # I used: 61130006663.
@@jinendow thank you very much! I will start next week. I hope the car runs after the conversion😂
@@cenkyurtseven2078 if you get the wiring right I'm sure you'll be fine!
Thanks for the video. How did you get the transmission out at that height (your car looks like it isn’t this high, 50skid posted a video where he says it needs to be at least 24 inches clearance from the floor to the lowest point of the car)
it’s been a while but I believe i lowered it on a trans jack and then placed the trans on a piece of cardboard while it was still under the car. then slid it out from there
Thanks for the video, great Job , I have an 05 that has a bad smg, it was starting for a while but now won’t start at all, I thinking about doing the swap to I’m a little nervous about. How lod did it take you to do it all ?
Eddie Hernandez I took my sweet time and it took about a week. if you have all the necessary parts you could for sure complete this in a couple days
a few days*
Thanks, I'm going to start gathering the parts need it and get more familiar with the process, hopefully my car will start soon
Eddie Hernandez good luck man! I studied and studied the realoem diagrams to figure out where exactly each part went
What's the name of that black cable with the pins in 23:19?? Where can I find it?? The ones that you solder to.
are you referring to the clutch switch?
What seats are those?
Did you notice any power decrease after the swap prior to getting coded? Just finished up my swap and had a local euro shop code it , no more dash cog but still getting a CEL for smg. Car also feels about 200hp until 4k rpm
before I got it coded I could definitely tell the power was off. the revs in between gears would drop aggressively and it felt as if it was in some limp mode. after I got the car coded by ecuworx it felt the same as before the swap though (as in perfect)
@@jinendow I’ll hit up ecuworx ASAP thanks !
Where you at, I would pay you to do it for me. Great job. Is that the same as CAE shifter?
thanks, it’s an rtd shifter. similar, but not quite a CAE
Where are you located? I would love to pick your brain on this swap after a year.
Every time I’ve removed the intake manifold off a S54 it loves to act funny for a bit ( cold start wise )
I’ll double check all my connections and yet it will still give odd starting conditions
Do you have a list of all the parts needed?
there’s a list on the forum DIY
Did you do this in az? How much would you charge?
Jeremiah HEREDIA no I did this in socal, and I’m not sure how much I’d charge
Hey nice diy! Did your cruise control work after the conversion?
just updated the comment section for CC
@@jinendow thanks for the update, I appreciate! your video is one of the best I have seen, I have spend hours researching how to do this conversion.
@@sheldonnadarajah no problem, good luck!
Oh god I hope mine starts
as long as you wired everything correctly, it should!
@@jinendow It did!
@@TheSandman121212 lets goooo!!!
Hi! Someone may have asked already, but where did you get those wires with the pins seen at 22:58? If you remember part numbers that would be great. Cheers ✌
I don’t remember the part number for this sorry!!
@@jinendow i also can't find wires like that anywhere lol
How much did it cost you because I’m looking to swap my e46 m3
if I recall correctly the parts were ~$2k
Why did you have to machine the bell housing? Pls n thx
there are certain detents and springs that need to be installed into the bellhousing that the manual requires where the SMG does not. If you use the self-centering shifter like I did you *technically* do not need to machine the bell housing but I still *highly* recommend doing it. If you read the forum link I put in the description they describe why better than I just did.
Did you use the factory welded in shifter studs when mounting the RTD?
yes
@@jinendow thanks. Literally was installing when asking you. I was kinda bummed I couldn’t use the thicker bolts but at least the stock studs were in right place! Were you able to get rubber boot on? Did you install it before bolting down the shifter?
@@kraken509 I believe I installed it before bolting it down
Did you pull the transmission off with a friend? I'm wondering if I will be able to pull it off on stands by myself.
I think I had my dad help me pull it off but if you have a transmission jack you should be able to do it yourself
@@jinendow Thanks!
Dear friend: how did you know the car won’t start because of the smg, instead of the starter for example. Thank you
tested possible causes and ruled them out (starter for example). the smg codes were also a pretty big giveaway
Nice work! How'd the coding go?
thanks! I got the coding done remotely by ecuworx and the process was real pain free
how many miles are on your car?
at the time 155k, I think it’s at 162k now
Can you swap it for me?
Mind if I grab your Instagram? Would love to ask you questions regarding not tampering with the gearbox itself! Thanks
Did you put oil back in the gearbox
yes
@@jinendow
Hoe much did it cost start to finish ?? Iv got a smg M3 in my collection .. always hated the smg even when they were new ..
My pin 8 isn’t empty on the ews, what do I do?
are you sure you’re looking at pin 8? I would double check if I were you. they’re labeled too
@@jinendow yeah it’s connected with a purple and white wire
@@jinendow is there a way I can actually be able to call/FaceTime or send a video of it anywhere? My wire guy wants to show you
@@axelgomez9022 yeah shoot me a message on instagram
@@jinendow what's up Jin I'm the guy doing the wiring for axel, the EWS module connector which is black and has 16 pins. It has pin 8 used by a purple mixed with white wire. And what's your Instagram by the way?
I didn’t hear you say you filled up the transmission with any fluid though
I probably just left that part out. so if you’re doing this, don’t forget to fill up
I don’t know why but I was thinking /typing out load for some reason. You did a nice 👍 job
@@fwhiteification haha no worries, thank you man
Starts car with new transmission with wheels on the ground
who machined your bellhousing
Grab America by the Flaps linked in description
There is no comparison between a manual and sequential transmission if you’re gonna buy an M3 and you don’t buy a six speed then you might as well not buy an M3 because you’re just wasting your money!
On the proud owner of a 2002 E 46M3 naturally aspirated pro charged M3 convertible that is a six speed manual. That is the ultimate driving machine not an automatic or a sequential.
If you’re going to knock smg you might as well knock the convertible too because of the extra weight.
dam those silly looking long shifters look so w*nk sorry
