When i swapped mine to 5.4l, 5 years ago, i kept C43 trans. & TCU for about 2 years, it was great without any issue,,

C43 & all 5.4l trans. are the same output, no any difference..!!

I'm interested in seeing the outcome of this thread
So what can we do to the 722.6 currently?
-Blue-top solenoids ~ maybe risky
-TCU ==> I remember reading in the W210 section regarding Eurocharged TCU tune.
- RENNtech transmission upgrade ~ $3600
So far the best transmission upgrades that I've seen are on (kaype )Fabian's car.
Here's the thread :

Don't you need ME2.8 for the blue tops?

Yes Indeed..

I stumbled upon this thread:

Some blokes believe that it'll work but with a severe downshifting jerk.

Solo wing

Zayed, you tried the blue-tops before, how bad was it?
is it unbearable to live with?
My 2002 E55 delivery date is : 17/08/2001 So I guess it has the Old ME

Yeah Faiz, i tried those blue tops, horrible damn big jerk especially 3-2>>2-1 downshift, absolutely can't live with them..!??!,

you have to see what's the part # of your ECU, may figure-out if it ME2.0 or 2.8,,

is your TCU, EGS51 or 52..?

So, after spending 3 or so hours going through wiring diagrams and reading descriptions of certain operations of the TCU (or ETC according to alldata), I still haven't been able to find the answer to my biggest question. Whether the KAM for the shift strategy is in the TCU or ECU. If it is in the TCU, then it looks like the relay idea should work and not harm anything. There is nothing linking the TCU grounds to security systems, windows, or even the ECU (ECU has it's own grounds). It also looks like there is only one or two grounds for the TCU. (I know some 2000+ YM Fords have 3-5 grounds for a TCU or ECU.) Our shop was pretty slow today, so I had a lot of spare time. If I find out the shifting strategy is stored in the TCU, I will double check everything I looked at today, and then test it out. If anyone here works at a benz store, or has their scan tool, try going into the TCU/trans and see if there is an option to reset KAM or strategies. If those options are only available under engine, then 10-1, the strategies are stored in the ECU and would probably be more of a pain to wire up than it's worth.
Another thing I noticed while looking at the wiring diagrams is that the pressure control solenoid has it's own dedicated wire ( May not be a shocker to any of you, but after being in nothing but dealerships over the past 8 years, I'm not use to seeing anything other than CAN networks in cars now.) The solenoid having it's own wire means the signal going to it can easily be manipulated with out having to use any programing or anything. (I use to manipulate computer inputs and outputs in all the cars in my signature along with my 2000 f-350 diesel and doing it for friends). That is something that would require even more research due to possible risks dealing with transmission internal failures (as if we don't have enough of those as it is! lol). I will certainly keep you guys posted as I figure out and eventually test more things.

Threads like this is why its so frustrating to be on this site. Overwhelming amount of misinformation.

Boost_or_die

Can you correct the misinformation? I think there's a good number of us in here interested in finding out if something like this is even feasible. I don't much on the technical end of MB. I know Ford pretty well (especially diesels) and a bit of Nissan's. For a select few of Fords, this would work. For most of the newer trucks though, you HAVE to actually use the scan tool to clear the KAM in the ECU or TCM. Disconnecting the battery for even an hour or two won't even clear the CEL on them.
The only stuff I have to go off of for our cars is the forums and alldata. All though, anyone in the dealer/manufacture world knows that alldata's procedures,times, and diagrams are correct to the manufacture books about 75% of the time (if that,lol)

did you ever try this? I was poking around with the laptop the other day and got thinking about you question. The adaption data is in the EGS as you can see which I'm pretty sure is TCU only but not 100%. that's why it's an interesting idea to try and see what happens. I'm wondering if there is just a way to edit the variant coding and lock the adaption values to a set correction.

Going pretty far down the rabbit hole but I know different variant codes have been written for manual swapped cars to have the TCU stop looking for a auto transmission so it seems maybe possible but your going to have to dig to find the right guy to do it for you.

Boost_or_die

I haven't had much of a chance to do much this past month. I was hoping benzslo would have some insight on the possibility of this. Is that screen pulled up for a c36 or c43 though? A couple years ago when I was trying to see if I could swap a manual into my c43, I couldn't find anyone who has done it. Only found a c36 or two.

Super B

Yeah this was pulled up on a 97 c36 with the 722.629.

A manual in a c43 now that would be an undertaking. There are a few threads about it but you better have DEEP pockets for a swap like that.
