93 300d 2.5 Turbo OM602 6 speed swap - Page 3 - PeachParts Mercedes-Benz Forum

I found a 91 190e 16v in a junkyard. The complete drivetrain was already gone, but I did get the floor shifter with switches, and the complete petal and master cylinder assembly. They also left the transmission support plate with the 4 15mm head bolts.

So the question now is which transmission to buy. It looks like the 2002 and older use the 3 rod setup; while the 2003 and newer use the single shift rod that goes strait into the very back end of the transmission, and a concentric slave cylinder.

I see a 2002 slk230 trans for sale, and a 2003 c230 trans for sale. Which one is compatible with the new flywheel/ clutch kits for sale? Anyone know engine is om602. Is the 03 trans too big for the 201? I'll make a new photo diy during the conversion, and hopefully help others with the findings.

Seems like the 03 transmission would be easier as a coat hanger wire test fit for length and 90 degree bends. Then use a piece of pipe conduit and a conduit bender to match the coat hanger test fitted piece. Then it just hovers in the floor shifter. Attach leather boot, knob, and maybe some foam for sound dampening.

Anyone know of any concentric slave cylinder/clutch/flywheel bolt issues?

Any differences between the 311, 312, 313 sprinter flywheels? They look the same. Please chime in, my auto transmission is dying fast, and I hope to start this soon.

This is fantastic and I think I am going to make the leap on my '86 190D 2.5 soon. These 6-speed transmissions are on eBay for under $500 in some cases. I know this thread is several years old, but if anyone has any experiences to share, I would appreciate it.

A few questions:

I want to make sure I get the right flywheel. They seem to be impossible to find in the USA, so I want to make sure. Its ok to use the conventional replacement flywheel from a Sprinter, or do you need the Dual Mass version?

I know this is a stretch, but I can't find the measurements. How does a w124 driveshaft measure compared to a w201? Could that make up the extra few inches needed?

What was your final solution for the speedometer? I'm wondering if I could just snag the gauge out of a c230 auto given that my rear end is 3.07 and as far as I can tell, the c230 auto is 3.06. Good work!

Those manual trans behind the Cummins are enormous. I don't think one will be very usable for a car.

I thought I'd share my experience since during my research I never found any info on what would defiantly work, only what "should" work. So now I can speak to what WILL WORK.

Here are my parts:

-93 300d 2.5 Turbo
-02 C230 Kompressor 6 speed
-02 C230 Kompressor shift linkage
-02 C230 Kompressor shift linkage mount (needs customized)
-311 CDI Sprinter flywheel, clutch, and pressure plate
-03 SLK clutch and brake pedal assembly
-03 SLK master cylinder
-Wilwood remote fill master cylinder reservoir kit
-Custom made 36" braided clutch line (need the master cylinder nut from the SLK and the trans connector from the C230)
-stock driveshaft lengthened 2 7/8" (if I was to do it again i would only lengthen it 2 5/8")
-94 E420 Electronic Speedo
-Dakota Digital SGI-5
-Intellitronix S9020 GPS speed sender (I do not recommend this, it is slow to react and looses signal easily, I will be replacing with a universal driveshaft speed sender)

2nd attached pic is the c230 trans 3rd attached is auto vs manual trans

Flywheel, clutch and pressure plate where bolt on, same amount of teeth so 100% compatible with stock starter and tach sensor.

Thanks so much for compiling all this. Do you have a budget figure for all the parts?

Looks like I need a parts car....an Slk, CLK or Chrysler crossfire. ...and a new flywheel from the sprinter.

Was the sprinter fw needed because the slk fw was not up to the job? Wondering about the weight of the sprinter vs the SLK?

If it is then you may have to get it from europe or someplace because I don't think that a manual sprinter was ever sold in the US

t walgamuth · #38 12-14-2020, 05:13 PM

Ahah!

t walgamuth · #39 12-14-2020, 05:25 PM

I just looked at ebay and found a dozen trans. I am thinking the six manual from the crossfire will work too.....$5 to 700 probably depending on miles.

ccrelan · #40 12-14-2020, 05:31 PM

You need to find the 6 speed that came behind the M111 engine hatchback coupe. The crossfire trans is set up for a M112/M113 style engine.

crossfire is a hatchback coupe (did you mean C230 hatchback?) so to make it more clear:

the crossfire was only available with the M112 V6

ccrelan · #42 12-14-2020, 06:45 PM

Any crossfire trans will not work on a diesel OM606-5-3-2 engines. It must be from the C230 hatchback coupe with the supercharged 4 cyl M111.

t walgamuth · #43 12-14-2020, 07:15 PM

Thanks for that clarification! Will a C230 be a good source for everything then? So needed is the trans. fw, clutch and pedal assembly and perhaps some odds and ends? I am still wondering about the sprinter fw....is that a more rugged upgrade?
