OM60X 6-speed - Kozuka - 05-15-2009
I just saw something very interesting today the 6-speed manual off of the M111 (W203 C230k I believe only 2000-2003) has the same bellhousing as OM60X and M10X. Man I want one...

RE: OM60X 6-speed - 2.5-10 - 05-15-2009
holy hell! if you get one, and it fits... I am getting one for my 190D Turbo! good find!
RE: OM60X 6-speed - ForcedInduction - 05-15-2009
Even supercharged, that engine only has 185hp/170lb-ft. I wonder if it could hold up to a diesel's torque. If you find a part number you should see if it crosses over to any CDI uses in Europe.
RE: OM60X 6-speed - Kozuka - 05-16-2009
I'll see if I can look it up in EPC tomorrow, I've got the euro edition
If only it was a get rag then I would be sure that it could take the punishment even if just for a little while.
RE: OM60X 6-speed - HoleshotHolset - 05-16-2009
I'd be curious to see how one of those compares to a T56...which are pretty dang stout, IMHO.

RE: OM60X 6-speed - 2.5-10 - 05-16-2009
I'm sure the T-56 is stronger, but the point is, this trans is originally Mercedes, and it should bolt straight to the M10x and OM60x motors without modification
RE: OM60X 6-speed - Kozuka - 05-16-2009
I would say stock power of a OM601,2,3 this trans would probably take with no problems with a 602 flywheel and clutch kit but if you throw a myna pump into the mix and a bigger turbo your on your own. A risk I would be willing to take if I could find one for a reasonable price. Good things seem to happen when I go junkyard hunting though.
But the linkage seems funky or should I say non-exsistent is it some kind of hydro line? I know there are some electronics on it what they do exactly is going to take some reading.
Still looking for the part number on this one.

Understood - I was alluding to the fact that the T56 is pretty stout and wondering how this 6-speed Merc unit compares with hard specs. It would be a viable alternative for those with relatively mild builds and if they can be found for cheap $.

RE: OM60X 6-speed - CID Vicious - 06-09-2009
For a stock motor that gear box should be fine. You'll notice road racers rarely are blowing up their rears or trannies, while drag racers do it all of the time. Driveline shock. The flex discs help but that means they'll wear out faster and they're not that cheap.
The best bang for buck is the W and R series boxes from Toyota, lots of applications (Celica RWD, Celica Supra, NA Supra (Gen IV), Lexus RWD cars with 5spds. And the mount pattern is freakishly close to the 617a, with the starter location in the right place. I think there's a link in the Franken Five Speed thread, guy has a 617a in his 4Runner. Simple fabricated 1/2" steel adapter plate. W handles 350lb ft (this is the common box), R upwards of 420lb ft (Gen III Supra Turbo, and that torque rating is almost equal to a T56.) T56s are great but they're not cheap and every Chevy nut wants one. (I know because I am, and because I do ;-) ).
I don't know if the 60X has the same pattern or not, but if it does then it practically bolts to this box too. Unless you're getting the MB six speed for free, you'd be faster with five and using the rest of the cash you'd spend on turbo upgrades/Myna. If you get lucky, find one for cheap and it bolts in, hey...

RE: OM60X 6-speed - HoleshotHolset - 09-29-2010
According to www.car-part.com, there's two of these little 6-speed units out of a C230 in WI and MI for $725 and $800 respectively.
Not 'cheap', but less than having my 722.608 rebuilt...
My timing in digging up this thread is due to the fact that my 722.608 is still goofed up and I need to come up with a solution. Ideal scenario would be bolting up a T56 or 4L80-E.
RE: OM60X 6-speed - snyder.hunter - 10-01-2010
I heard today from one of the largest Mercedes parts suppliers in the USA that this engine is not well known for its reliability so to think about putting it behind something with more torque than it is used to sounds like it might be risky....

Is the engine unreliable or the transmission?
I've heard that these supercharged 4-bangers are unreliable, never heard about the 6-speed transmissions, though...
RE: OM60X 6-speed - willbhere4u - 10-04-2010
If the engine's suck that means there should be more transmissions available as the cars become worth less money! yea!
More supply less demand kind of situation!

I was told the transmissions were not known to be all that reliable, but call Potomac German Auto to confirm that. Don't take my word for it. Often time someone on the internet says some part actually is really awful or unreliable when in fact it actually isn't, or is used in a way that will cause premature failure. This then starts a huge rumor that the MB 6 speed trans is unreliable...We need solid proof of this or that. Anyone want to chime in on their thoughts of this transmission and its reliability?
Who knows, it good be very good. And yes, if the engines are unreliable then perhaps more cars will be junked... that's a thought.

Being in the biz, I can't say that we've seen a lot of catastrophic issues with the W203 C230Komp's, at least over here on the west coast. They're good little engines. Maybe east coast engines are different
but we have quite a few clients with them and they're solid.Granted they don't make a ton of power so trying to hold a turbo diesel reliably for a long while, I'm not certain about that.
Since I'm looking for my own 603A/606A swap, what have the proven 5spd/6spd manuals been so far?
RE: OM60X 6-speed - willbhere4u - 10-05-2010
I'd throw one in my 300sdl in a heart beat when I can find good a cheap one!
RE: OM60X 6-speed - willbhere4u - 11-22-2010
I am really thinking of doing this swap over the 5spd option!
An om602 flywheel and clutch seam like a good option even if my 1987 300sdl is a lot heaver and a bit more powerful did they make a turbo om602 with manual trans?
I noticed that the shifter linkage looks like it would be more positive feeling? It looks like a rear tail shift kinda deal no more goofy shift rods!
Has any one driven one of these 6 spd cars? how well do they shift?
RE: OM60X 6-speed - mk216v - 11-22-2010
A G-Wagen guy in Cyprus has built two early W460 G's with the 606A. He's using the Sprinter 2.9TD (same as G290TD) 5spd manual. FYI...

Very good find!
I've never seen a Mercedes on this side of the pond with a manual transmission...so these must be sort of rare.
Cheers,

RE: OM60X 6-speed - willbhere4u - 05-02-2011
I got one at a local junk yard out of a 2002 c230 2.4 kompressor for $800
they are rare but not as rare as a 5spd for a om617
They also offered the SLK with the 6 spd and if its off the 4 cylinder model it will bolt up to any om60x engine!
like my 1987 300sdl with om603
RE: OM60X 6-speed - mk216v - 05-04-2011
How strong are these manual trannies...ie for a slightly modified 606A?
RE: OM60X 6-speed - muuris - 05-11-2011
I've had 716.640 in my 450hp OM606 for some time now, no problems so far.

That's really encouraging to hear. 450hp OM606 is well over 800ft-lbs and I know you Finns don't take it easy on your transmissions.
I guess the transmission from a C230 Kompressor can really handle some decent power. There are quite a few of them on www.car-part.com right now...

RE: OM60X 6-speed - willbhere4u - 05-11-2011
It's all about how you drive it! I stuck the 1st and revers gears out of the side of my transmission case on a 240d 4spd with less than 60 hp!
loose shifter bushings caused 1,2 to engage at the same time when pulling out of a light it went bang and I only had 2,3,4 to get me home!
I've never actually seen a manual transmission break from power alone even in my racing days

Indeed. I think an OM606 with 450hp/800ft-lbs in a Merc chassis would be heavily limited by traction - so that helps a bit.

Good to hear!
To confirm, 716.640 is the 6spd from what year/model/engine?
C230 Komp?
SLK Komp?

Hi
Mine is from a 220 cdi 2001
