Is it possible to swap a manual transmission for an automatic transmission with step-tronic on a 2008 M3?

Nothings impossible with enough $$$, tho, u might wanna consider getting a new car after selling yours...ive seen a guy did the same, but costed close to 10000

[secondgear]

not worth it.. just trade it

wow! Unless it was a super high-end car, he got hosed.

Its possible, but these cars arent something you can go grab for $500, and have a donor car. Cheaper to sell, cut your losses, and grab another.

you want to ditch your manual tranny, for an automatic?


WHY!??!

and are we talking mazda3? or bmw M3?

[n00bMeiSter]

Dent: I like the steptronic option a little better, allows me to be more concerned with other things but still have manual fun. Plus my gf and family don't drive stick. So if they need to move or drive my car they'd be sol. My father hasn't touched stick since he sold his 70's firebird trans am when I was born (and I'm not entirely sure he had a manual firebird lol), so I don't trust him with my clutch lol.

I would be up for the trade . I have on 05 Auto.

Get a a shop willing to do the work and let me know the price ...

swapping a manual to an auto is as hard as swapping from auto to manual

this isn't the olden days anymore son... you got to swap all sorts of parts like computer modules, wiring, etc

what's definitely going to happen is your car's warranty is voided and your resale value GONE

the time and money wasted to doing something ridiculous like this is going to cost way more than an upside down trade to an equivalent automatic car

Not true . I spoke to my mechanic about this. Auto to manual is easier than manual to auto.

Wiring ? Maybe. ECU from the auto will work on a manual ... do your homework. The checkengine light will stay on becuase it wont be able to detect the autotransmission. Other than that , the car will function the same.

Time and Money? I have been quoted 8hrs just for labour ($80/hr x 8hrs =$640). If OP wants to swap transmissions with me , the 640 is all I have to pay (minus whatever I charge him for my Auto.... afterall, auto is worth more).

Warranty ? Not a problem for me.... but will be for the OP.

Well I knew that much.

Why would the resale value be gone? auto's retain value better than manuals. or is it because the transmission doesn't match what the vin lookup says?

I cant imagine it costing the same, the cars I'm looking at are ~$19,000.

You're going to have a hack job. That's going to screw resale.

[bman13]

Just trade it in...

this

and for a complete swap, it'll be the transmission itself, new gauge cluster (unless you want the PRND lights on the dash), wiring harness, possible different mounts, differnet center console, clutch pedal, etc etc etc.
just trade it in.

"your mechanic" doesn't work at mazda does he? let me know if he does because what I do know is, you're making it sound simpler than it is... theres too much wiring differences involved because the 3 uses a canbus system... just saying whatever is originally there will work is all BS... there's many other computer modules that will freak out and the car will just be a total mess unless you rewire everything and replace all the different electronics and program them to work right

just paying someone to deal with the wiring/electronics isn't the real problem... the real problem is finding the right guy/place to do it! most people out there suck at the electrics and the cars end up being all mickey mouse... but when you do find the right guy to do it, it'll cost you thousands more over just the major mechanical parts

the most optimistic cost is probably $3000 and that alone is enough to justify an upside down trade for an auto mazda3 that WON'T be a hack job, and will have less than 1% chance of electrical gremlins over the unknown odds with doing a swap

why don't u two just switch CARS!

problem solved!

More people do transmission swaps than you would think , just do a google search. I'm not sure about a mazda, but people do these things on nissans/Vdubs/hondas all the time. Everything works fine for the people that want to go from auto to manual . But like I said earlier , to go from manual to auto is a different story.

^^^ Example of a Jetta going from auto to manual with NO PROBLEMS

[condor888000]

I know a guy who did a auto to man swap in his Protege. DISASTER. His speedo never worked again(4 years), neither did his reverse lights, and there was a shitload of other random stuff that just didn't work right.

Not worth the headaches IMO.

lol no thanks.

[chinsterr]

I was hoping a little project like this would keep me interested in my car , but meh, new car hopefully coming next year.

[notoriousb]

Some car's it is easy to do things....

The mazda 3 is the biggest headache in the world regarding wiring, and how everything is interconnected.

There are like 20 different (front) wiring harneses for the entire lineup of mazda 3's including some that are for cali emm cars, to federal emm cars, to manual, to auto, to 2.0 to 2.3, etc. This is not to mention the different options for the car -- like ones with xenon lights, to ones without, to ones with DRL's--- this is on top of the different years... as 05 changed from 06 to 07 changed...

Good luck finding the same car you have with the same wiring, just auto(instead of manual).

Computer would be different, guage will be different -- means you have to get them reprogrammed for your key.

I'm not even mentioning that its a different wiring harness inside the car lol.

Don't try it ... trust me ... I've dealt with wiring this car -- it's something you never wish on your worst enemy lool.

(the actual transmission in and out is the easiest part of the whole process !!! lol)

[Hives]

its do-able
speak with Dan, I had a conversation about this with him before
you'll need a good mechanic for sure. Go to a scrap yard and find a manual 3 and pluck all that you need from it. Not sure how much it will cost though, but im pretty sure its gonna break the bank.

[SKYMP3]

That's if you have time and money to spend, but all this on a Mazda 3? lol.......

Manual or automatic Mazda 3 are everywhere on the road. I don't see what will be a good cause for doing this swap, boost up your 3 to 300hp give me more respect.

[x_o_k_x]

its possible but there is ALOT more work to it then you could possibly imagine

[1flycdnM3]

like it has been mentioned before, the wiring on our 3's is absolutely ridiculous. I wouldn't wish a swap like this on my worst enemy, let alone the value lost because of doing this. I have seen people do this (and helped a little) on a honda before and even that was insane! The wiring wasn't too bad (maybe because i understand Honda's alot better), but the car still needs alot of work even a year AFTER the install.

For that price, rather learn how to drive manual (since it's not that difficult) and buy a turbo or mods or whatever. Waste of money to do a tranny swap, IMO.

I think you misunderstood me, I'm looking to go from manual to automatic, not automatic to manual
