Ah. Righto. Thanks. Do you know exactly what's different? You said we could do it by just switching to the blue solenoids, is there anyway you can confirm this.

If I don't have to spend oodles of money on a whole new valve body, I might actually be the guinea pig and try out this mod

Okay, I just confirmed again with my parts department.

ALL C43 transmissions have the #140 270 01/02/03/04/06 06 valve body assemblies including the 2000 C43 w/tip.

1) replace the brown top solenoids for the blue top solenoids #240 270 00 89 ($160.80 each)

2) replace shift assembly from #129 260 45/46 98 to #202 267 08 24 ($426.72)

3) replacing TCU EGS51 from # "021 545 84/86/87/88 32" to EGS52 #025 545 21 32" or "027 545 10/12 32" or "030 545 20/23 32 ($150.00)

4) Guage cluster with gear display

So that should be a final list of parts for the tip conversion, plus wiring from the gear selector to the cluster to show the gear display??

Can anyone confirm the need for the blue tops? This is an upgrade in W210, W203 and W211 cars, so why would tip not work in our cars without it?

If you or previous owner NOT replaced the valve body, it surely comes with "04 06", the MB replaced it to "06 06" or "00 06", the only different between

"04 06" & "06 06" & "00 06", (the linkage arm that holds to the bottom Electro. piece & the middle filter behind the speed sensor),, you can put the blue

solenoids only in your exsist valve body,, but in this case you well force a hard firm shifts specially in the 1-2, cause the switch in the +/- gives a different
signal to the valve body,, that’s why MB NOT sold that switch separately..........

ZAYED,,

Okay. The transmission was replaced in 2007, so for now, I'm going to assume I have the updated 06 06 or 00 06 valve body.
Once I'm back in NC after school is done I will hopefully take it to my shop who can drop the pan on the tranny and get my p/n from the valve body.

For now though:
I have ordered a 2000 E55 TCU and will soon be ordering the new shifter assembly.

Hopefully, I'm going to install just the assembly and see what happens. Then I will add the TCU, Blue-top solenoids and/or updated valve body as needed, and then hopefully we will all have a clear idea of EXACTLY what is needed to do this upgrade and a cost

From there it is smooth sailing on the way to being the only W202 with paddle shifters

I do not think it will work with just the shifter assembly as your TCU will not understand the signal it is receiving from the shifter. Keep in mind "P", "N", "R", and "D" are the only gears that are shifted mechanically, "4", "3", "2", and "1" are all electronic. If it did work you wouldn't be able to shift manually through the gears. Everything I had listed above will need to be swapped to have a legitimate swap to the NAG 1 shifter (and in turn paddle shifters)

That's very good, you definitely got the update one,, as i said before you don’t have to replaced the TCU, first thing put the blue solenoids without

replace the TCU and see, if it works without any issue, that means everything OK,, but if isn’t, then you have to reprogramming it, to match a new

signals,, don’t forget something important; since you well keep your 3.07 diff., it means you have to reprogram your exist TCU, but if you well put an E55

2.82 diff., you well have to switch the TCU to the newer one, with fully RESET.........

ZAYED,,

As there are conflicting views on replacing the TCU, I will do just the shifter install while I'm getting the E55 TCU reprogrammed. Then if that doesn't work, I will put in the TCU and try again. If that still doesn't work I will put in the Blue Tops (which I will probably ending up doing anyway at some point) and if that still doesn't work, I will consider springing for a different valve body.

Zayed: I don't understand how changing the solenoids affects the abilities of the transmission. I thought all the blue tops do is increase the pressure over the brown ones?

Everyone else: If anyone happens to know the part number of the harness that goes from the shifter assembly to the instrument cluster to show what gear you're in, I'm in need.

In generally: the TCU controlling the signal from the MAF & ECU, in the mean time; it reads the Exact ratio from the diff., by the speed sensors, its soo

important to know the TCU has directly related to the diff. ratio in your car,, sure, the blue solenoids gives more fluid pressure = more strong & fast

shifting, and also helps to prevent slippy between shifts, thats why MB replaced all browns to blues, after 2003,, there’r "2" #s:

"202 440 69 09 or 202 440 70 09", depend of MB production for these harness #s.........

ZAYED,,

Ah, Sorry,, i forget to tell a side note,: if your EGS # start with 020 or 021, that means it can’t be programmed, should to put the one from any models

with 2.82 diff. ratio,, "{this note only incase if you go with 2.82}"....

ZAYED,,

What about a 208 CLK 55? Does it take the same ****er as a 202? What differential is in it?

CLK55 uses 2.82 ratio, with different housing & End cover than the C43 one.......

ZAYED,,

I read the W202's that were converted to C55's had the floor pan modified to fit the CLK55 diff.

If the 55's are using the 2.82 diff wouldn't that decrease their off the line performance???

As i know; AMG swapped the gear & pinion only from CLK55 started with 220 #,,

its very good point,,: when i swapped my Engine to 55s, i kept the original diff. which is 3.07,, i raced my friend "3" times,(who has a true C55 with 2.82

diff., i felt his weak point from the 2.82 side,, i think maybe AMG put 2.82 for hit the limiter final speed to reach more than 290km,..!!, i personally like

3.07 or smaller like 3.27........

ZAYED,,

If I had to guess I'd say yes, it would. Probably because AMG knew these cars have traction issues, so to make the upgrade really worthwhile they gave it more top end instead of more spinability?

Yup, it is the same shift assembly. #202 267 0824

Looks like I'm going to be testing all this theory soon. I already have a valve body, shifter, and a CLK 55 trans module. Now I have a CLK 55 diff on the way. I'll be able to document the entire process. The only thing I don't have is an instrument cluster for gear indication.

Does the e55 gearbox go straight in to c43? together with the 5.5 engine. I know the 5.5 goes in but i want to put the e55 gearbox with tiptronic

Yes: the e55 trans will go right into the C43. No: you will not just magically have tiptronic. Tip is basically all electronic (except for the obvious shifter portion) as long as you have the updated valve body. Not sure when they started putting them in, but all 2000 models have them, and if you have a replaced or refurbished trans, chances are you have it.


As the rest of the tread states, you also need the updated TCU (EGS52) to run Tiptronic, and the shifter assembly from a 2000 C class or a clk. If you are getting the trans from an E55, unfortunately there's not much else on the car that you can use. The shifter assembly is a different size than ours, and while the TCU is EGS52, the W210 has a different size rear end than the C/CLKs, so you'd have to get that reprogrammed, and you may run into other problems somewhere.

Is the e55 quicker than clk55? So if i put engine and gearbox from e55 with TCU and shifter from the clk everything should work? Does the wiring need to be changed for the gearbox? And does the same drive shaft fit the e55 gearbox?

what about steering wheel on 2000 cars?
is it modified?
does it have shifter buttons on the backside of steering wheel?
if yes then a new s-w might be needed?

In theory, yes, that's all you need. If want to see what gear you're in, you can get the instr. cluster from the E55/clk55 and use it, and wire up the gear indicator light, but that might tempt you too much to get the Multifunction steering wheel so you can control the cluster, and then get the whole Command unit to finish it all off.
I think I mis-spoke earlier though. The CLK55 has the same rear end as the E55, a 2.82 I think. Our C43s use a 3.02. You need to find a car, with EGS52, that has a 3.02 from the factory. Or you can upgrade the diff to one from a Clk55 or E55, but that is a headache all in its own right. The other option is getting an EGS52 and then hoping to use STAR to change the diff size in the computer.
Also I don't believe the wiring to the trans is any different, and I'm not sure about the driveshaft.

Also keep in mind, if you go through with this upgrade to Tiptronic, you are being the guinea pig. Members on here have talked about this for a while, but no one has gone through with it yet.

Steering wheel's the same. No paddle shifters or anything. That was going to be my next step after doing the Tip

The cluster to show gears i have already got installed in my car complete with multi function steering so thats a start. How would the display show gears if no additional wiring is needed?

I thought someone has done it already what would be worst case scenario?

TriStarTech and I were most recently the two biggest people looking into this upgrade. I didn't get around to it this summer as other things came up, and I haven't heard from Tech for a while.
You will need extra wiring to show the gears on the cluster. Unfortunately I don't know exactly what's needed, but it shouldn't be too hard to wire up.
Worst case scenario would be you buy a bunch of stuff and it doesn't work. In which case you should be able to leave the e55 trans (assuming it fits the driveshaft fine) and put back in the orig. c43 TCU and shifter, and it should work just as it does now.

I really want to do this mod the only thing i am concerned with is the gearbox not fitting. I spoke to someone he said the shifter is coded and would need coding and also have to change ESP unit so really mixed reviews
