Please feel free to send any info out. I should really emphasize that this is not something that is terribly easy. Putting the transmission in my car took a few hours including the shifter and changed the shift linkage length and changing the cooler lines. I have been working on the shifts for a couple of months. The main thing is that every car with every different engine and gear ratio will be different. I have talked to PCS about this and they turn people away all the time because they feel that the person would not be able succeed and they do not make enough money on the TCM to give the support needed.
I have talked to them about becoming a dealer for their product in my area, we are still working out the details for the 722.6 before I go further.
It works it just shifts a little to firm at low throttle input. I am waiting to switch to a map reading for shift pressures until I get this last solenoid timing problem fixed.
It also requires a electric speedo. or a adapter driver. I took one from a 400e.

I'm liking the sound of this TCM if you can indeed get the software sorted out. I reckon it could be pretty cool hooked up to a Twist Machine Shrifter which appears to be compatible with the PCS TCM.

I wonder how much massaging would be needed to fit a 722.6 in a W201 tunnel. Did you happen to compare the size of the 722.6 vs 722.3?

Have you got any pictures of the shifter install?

I am planning on installing a paddle shifter in the future. I did not take measurements. But it is definitely bigger around. It is just a tiny bit longer. My driveshaft just hooked right on.
The shifter I put in is the wrong one for my car. It is to tall and long. But I had it already and my car has lost a lot of the refinement that makes me care. I just trimmed the wood to fit. I have looked at shifters though and the ones from the c class and are identical in size to the original. The bolt pattern for installing is the same on all of them.

just wanted to show my oil filter relocation. making room for my new intake.

Can't wait for that 722.6 . . .

:-) neil

Neil, what car would you like it on?

Yes

We talked about putting this into my M120 107. That is definitely a way I want to go in the futer but I was unaware that the 722.6 trans could bolt up to a M117. So I could have my other 560SL with a 5 speed OD transmission winter Summer selectable. Cool. What application fits the M117.

I have not personally checked this but I talked to a guy who had used an transmisson off of a m119 on a 560 motor.
Any way I would double check before I got to carried away. The way I check is
check the case number for the 722.3 and cross reference. If the case is the same just get a 722.6 from the m119 motor. You can also get the bellhousing seperately for about 5-600 dollars.

722.6 on my C36-powered (aka, M104-AMG) W124 wagon.

Then I can go back to either my 3.07 LSD or 2.87, and still have 5th gear for good gas-mileage (currently running 2.65).

BTW: wasn't there a 6-speed manual for the SLK320 and C320 ?

Shouldn't that bolt-up to a M104 engine block as well . . .

:-) neil

No it won't. The only newer U.S. manual that may bolt up would be the one on the kompressor motor from the slk or c class. m111 motor.
The 320 motor is a m112 and has a different bell housing. Besides the PCS controller can be used with paddle shift in a full manual mode if that is what you are after.
For stick shifts the best way is to import from europe. And then you have a sloppy mercedes shifter.

I am projecting total cost on the 722.6 conversion to be in the 4000 price range. May be a little more. That is with a used transmission and shifter.
The install is pretty straight foreward. Just repl. the trans with the new one and repl. the shifter. Then the only modification required is the shift rod length. The install of the TCU is pretty straight foreward. It needs throttle position and map and wheel speed, power and ground. The mapping is the big work out. But I should be able to get this pretty close for most applications. I think that on similar cars this will work. I error on the side of firmer shifts.
For the other cars out there I would need to spend some time with one to get the shifts correct. The 500e guys we just need one to start with. Then we could use the data from that one for others.
But any diff gear changes would change all the info. and big horsepower changes also.
For your application I think we would be pretty close to the same tables I will be using.

The thing about the M111 manual transmissions is that, at least the one I saw recently on ebay, there isn't the same hole for the starter. Made me wonder how they do it, I don't know, but there weren't no hole.

I cannot remember what it looked like. It has been a long time since I worked on one. It should fit though. The bigger problem would be finding one, and then getting the pedal assembly and shifter, although the shifter may fit from a slk also.
Them m111 has the exact same belhousing as the m103-104.

There's the one I was talking about. I mean, you probably know more than I do. I'm sure I'm missing something. Let's expand this information, because I want someone to do it, so I know that I can do it in the future if I want to. 6 gears instead of 5 sounds cool to me. Unless somebody wants to donate me a 6-speed I'll test fit.

This transmission is from the later cars. 2006-2007. Either the aluminum m271 or m272v6.
It will not work.
You need something from the m111 from the late 90's to the early 2002-2003.
The r170 chassis is the only one I have ever seen with the stick shift on the m111. Maybe a 203 coupe.

Oh, I see my error then.
